XMap Q&A—Why choose XMap as a component of your GIS infrastructure?

March 23, 2010 by xmap

Today’s GIS professionals face a bewildering array of choices when it comes to selecting an appropriate mapping solution—from powerful and expensive desktop or server based packages to Web mapping tools to open source or freeware alternatives. In addition, GIS decision makers must choose which supplementary add-on or plug-in functionality will be needed; how critical data will be deployed to an expanding mobile workforce; and, perhaps most importantly, where to find a suitable base map.

DeLorme’s XMap holds a unique position in the GIS landscape as an all-in-one solution designed to simplify the use of mapping technology for companies and organizations of every size. It includes all of the spatial data management tools that the majority of GIS users need for a fraction of the cost of traditional GIS software package. It is the only fully-functional GIS application that was developed by a map-making company; consequently, it includes an accurate, detailed, and customizable topographic base map as the foundation for all GIS projects.

So what advantages does XMap hold over other GIS software packages?

Value
DeLorme’s approach to GIS has always been to expand access to mapping technology to as wide an audience as possible by offering software at a budget-friendly cost. Starting at under $200 for the Professional edition, XMap has proven time and again that it is possible to quickly see a return on investment through increased productivity and improved workflow efficiency.

Usability
DeLorme developed XMap on the same platform as its award winning recreational software titles. As a result, the interface is easy to navigate, the GIS data management is remarkably intuitive, and the learning curve is relatively gentle. A GIS can become a drain on resources if a disproportionally high percentage of time is spent trying to learn how to use the software. XMap’s uncomplicated layout ensures that your GIS will be up and running in no time.

Straightforward Three-Tiered Approach
XMap is available in three levels, differentiated by the degree of GIS functionality that they offer. All three versions are preconfigured with all of the features required for their intended use with no need for additional plug-in or add-in components. XMap GIS Enterprise provides corporate GIS management tools; XMap GIS Editor is ideally suited as a standalone GIS application; and XMap Professional is a low-cost GIS viewer, or, when used with XMap Forms, a field GIS data collector.

Base Map Dataset Included
For over 35 years, DeLorme has produced software and hardcopy map products of the highest quality and, as part of this process, has assembled one of the most complete and accurate map datasets available anywhere. As a byproduct of this effort, XMap includes a high-level reference base map for the entire world as part of the standard installation and every XMap software bundle includes a copy of DeLorme’s unique vector-based topographic map for the U.S. This highly-detailed dataset is preconfigured and adheres to DeLorme’s strict cartographic standards.

Access to DeLorme’s Innovative Map Library
Subscribe to the Map Library for under $30 per year and you will have at your disposal one of the most extensive imagery and map data archives available anywhere. The Map Library collection includes U.S. color and black and white aerial imagery, USGS quad maps, Canadian topographic maps, satellite imagery, high-resolution city imagery, and NOAA navigational charts. Download as much as you need, when you need it, and it’s yours to keep.

Interoperability
XMap supports a wide variety of third party GIS and CAD data files in both raster and vector format, allowing it to seamlessly integrate with your existing GIS infrastructure. The Enterprise edition even offers the option to access data layers directly from an ArcSDE database, eliminating the need for manual file export.

Free Support
If you ever have a need to call a member of the XMap support team, you can be sure that you will receive the help you need. The technical support group works closely with the software development department and they are intimately familiar with the workings of the software. Best of all, you will never pay a penny for technical support.

For the ultimate in flexibility, the XMap Enterprise License Agreement (ELA) allows an IT manager to efficiently manage the installation of XMap throughout a company or organization.

Integrated GPS functionality
For over 20 years, DeLorme has not only offered support for GPS technology through its various software titles, it has been a pioneering force in the development of inexpensive GPS receivers.

XMap interfaces with GPS in two ways:

  • Real-time positional tracking and navigation
    Connect any compatible GPS receiver and click the GPS button on the toolbar to display your current location on the map. Used in conjunction with XMap’s route planning functionality, this transforms XMap into a powerful in-vehicle, voice-controlled navigation tool.
  • Data collection and transfer
    Waypoints and tracks can be exchanged with virtually any handheld GPS receiver, although for true GIS data collection functionality DeLorme’s Earthmate® PN-40 GPS is the clear choice. Utilizing XMap Forms capability, this remarkable device serves as a field-based extension of your GIS providing access to raster and vector layers and offering full attribute data collection.

Efficient Data Distribution
The Enterprise edition of XMap has been developed to enable the distribution of pertinent data to a wide audience using a simple synchronization procedure. When combined with XMap Forms, this synchronization becomes a two-way transfer process allowing data collected or edited in the field to be automatically integrated into a corporate GIS layer.

XMap Forms
Enabled using the Enterprise edition of the software suite, XMap Forms offers a user-friendly means to collect or edit GIS data, including attributes on a GPS-equipped laptop computer or on the Earthmate PN-40 GPS receiver. XMap Forms simplifies data collection and ensures data accuracy and consistency using drop-down lists, check boxes, and simple text entry. This unique component of the XMap suite provides true mobile GIS functionality using inexpensive off-the-shelf technology.

Embedded Documents
This notable addition to XMap’s spatial data management toolkit offers the means to attach an external file in virtually any format to an object in a GIS layer. Anyone with access to this layer can click the object on the map to upload, open, and even edit the file or document. The modified version is then automatically saved in the database.

Peripheral Functionality
While the primary focus of XMap is GIS data management, the software suite integrates an unparalleled collection of additional mapping tools that have been developed throughout DeLorme’s 30 years of innovation in the field of spatial technology. All versions of XMap include:

  • Image Registration
    Transform any image file, such as a scanned map or aerial photograph, into a geographically referenced map layer

XMap at Work—Using XMap to Help in Wildfire Management

March 23, 2010 by xmap

In the field of wildfire management, GIS and GPS technology are becoming important tools, not only for the management of ground operations and the creation of incident status maps but also for real-time monitoring of critical data and position when the firefighting effort takes to the air. By combining easy-to-use GIS functionality with GPS navigation, XMap offers a truly unique and incredibly valuable tool for this application.

The following excerpts are taken from an article written for Wildfire Magazine by Mark Zaller and Dan Ward, both Air Attack pilots, on the critical role played by XMap in tackling wildfires from the air. The article describes how they have implemented a unique application for XMap that provides an airborne GIS platform used in tandem with infrared (IR) photo and video capture. This combined technology allows the team to monitor the terrain, record the flight course, make on-the-spot decisions based on GIS-based information, and capture a visual record of the mission.

“DeLorme XMap is the only software that does it all, because GIS files (ESRI .shp) are directly imported without translation. Every morning GIS teams upload their data on to ftp.nfic.gov and downloading these maps is as free and easy as surfing any web page. Loading the GIS on the plane’s systems is another one of those drag-and-drop maneuvers. Start DeLorme XMap GIS while on the ground, drag-and-drop today’s files on the computer map.”

“The system always runs automatically showing IR, moving topographic maps and fire GIS. For those who do want to touch the map, a mouse click will zoom in to the name of everything all the way down to individual buildings, or out to see the big picture.”

“Sending maps and IR photos to the Incident Command Team on the ground is a bi-product of this technology. We in the air want IR and GIS for tactical reasons and for safety. Because the equipment is easy to use, the IR and moving map with current fire overlays has become like another window in the airplane.”

“Seeing crews through smoke while circling above, identifying fire lines before arriving, zooming into the name of every bump, creek, and road, and instantly finding hand-cut lines or drop points, is all worth its weight in gold.”

“The moving topographic maps in XMap can be oriented in direction of flight and show agency boundaries along with detailed maps, and of course our fire perimeter as mapped by the GIS technicians. Improved safety and situational awareness is elevated to a new level for the Air Tactical Group Supervisor (ATGS) and pilot. Aerial firefighters say IR and GIS is a 30% overall improvement in tactical effectiveness, and possibly the best new thing since using the airplane for Air Attack.”

“Capturing video is also incredibly useful for airborne operations and when used in tandem with XMap, whole fires have been translated to a map within about 30 minutes of the first Air Attack aircraft landing; long before an infrared helicopter arrives or the GIS team has assembled.”

“Watching the video is almost like sitting in the back seat of the aircraft with GPS track previously recorded by DeLorme in one window and the video at the same time in another window or a second display. The moving-map GPS window shows precise location at every instant, and the rolling video is like looking out the window as you virtually fly along. Now without getting airsick anyone can easily draw fire lines until they get it exactly right by simply rolling the video.  This system can do the work of a whole team of intelligence field observers in just a few minutes from the safety of a cool office.”

Tab Tip—Using XMap’s Embedded Document Function to Manage Files Geographically

March 23, 2010 by xmap

XMap’s embedded document function, which has been an integral component of the software for several years, was introduced as a means to associate files with individual objects in a GIS layer and to store a version of each file in the XMap database. The primary intent of this function was to provide an efficient way to attach supplementary information or data about an object (for example, a photograph or a schematic diagram) that could not easily be assigned to the available attribute fields and to ensure that anyone with access to the layer would also have access to the associated files.

The original embedded document tool was designed to allow the associated files to be opened and, if necessary, locally saved; however, there was no document editing function that would offer the end user the ability to modify or update the file. If a field worker was required to fill out a report at the jobsite and the blank report was attached to the appropriate object in the GIS layer, the technician would have to save a local version and send it by e-mail to the project manager.

New Embedded Document Functionality
The embedded document feature has been significantly enhanced in XMap 7:

  • Embedded documents can be opened, edited, and saved back into the database.
  • Documents can be uploaded from the attribute table or by right-clicking at the location of an object on the map.
  • When employing XMap’s data synchronization function, newly uploaded or edited documents are automatically incorporated into the master layer.
  • When using XMap Forms, image files uploaded as embedded documents are displayed in the form itself.
  • Documents can be uploaded using any version of XMap 7, although either the Editor or Enterprise version is needed to create the required document field.
  • An initial value can be assigned to a document field so that a default file, such as a blank report, is automatically added when each new object is created in the layer.

Embedded Document Considerations
There are several key issues that should be considered when setting up embedded documents:

  • To upload a file or document, the layer must have an attribute field with Document assigned as the data type. This usually entails manually generating the field after the layer is created or imported.
  • Virtually any file can be uploaded using the embedded document function. XMap does not open the file so there is no internal compatibility or formatting issues. Instead, the action of opening the file triggers the appropriate application as assigned within the Windows® operating system. For instance, if bitmaps are normally opened with Microsoft® Paint, clicking an embedded bitmap will launch that application as well.
  • Embedding a document creates a new version of the file that is distinct from the original that was uploaded. If the original is edited, these changes will not be reflected in the embedded version.
  • Access to the file or document is through the local or central XMap database within which the GIS layer is stored. Unlike a URL which works by recording the path to the original file, embedding the document allows it to be opened at a remote location.
  • If multiple files are associated with a single object in a layer, a separate document field will be needed for each file. For instance, if there are four photographs associated with a GIS object, four document fields will be required.
  • OpenSpace GIS layers with embedded documents will be significantly larger, which is an important consideration when synchronizing or manually sharing OpenSpace transfer files.

Setting up a Layer to Allow Document Embedding
Before uploading a file, the layer needs to be configured to allow documents to be embedded through the creation of a document field. This is done using the following steps:

  1. In the GIS tab, click the Attributes button and select Design View.
  2. Click the Options button and click Add Simple Field.
  3. Type a name for the field, which will appear as a column heading in the attribute table.
  4. From the Data Type drop-down list, select Document.
  5. Click OK.

Note that a document field cannot be created using a formula so the Add Formula Field option does not offer Document in the data type list. If Add Constrained Field is selected, Document is available as an option in the data type list, but the only constraint that can be applied is to assign a specific document as an initial value. This means that all new objects will include a copy of the same embedded document. This does not, however, assign the document to existing objects in the layer.

Uploading Documents
There are two methods for embedding a document within an object in a layer:
From the Attributes Tab
In the Attributes, Datasheet View, scroll to the document column and locate the required object in the attribute list. If no document is present, the cell displays the word <null>. When the cursor is positioned over this cell, an arrow automatically appears and, after clicking the arrow, a drop-down list is displayed. Initially, the only option is Upload, which opens the Upload File dialog box from where the required file can be selected. After uploading the file, the file name will appear in the cell.
From the Map
After positioning the cursor over the appropriate point, line, or polygon on the map, right-click and select Documents. If no existing document is present, the only option will be Upload, which opens the Upload File dialog box as described above.
Opening, Editing, and Saving Embedded Documents
If a document or file has been uploaded and associated with an object in a GIS layer, there are several additional choices in the Documents drop-down list on the map or in the attributes table. The list now includes View, Save As, Upload, and Delete. Additionally, if the file is in an editable format such as text, Edit is also available. The Edit option allows the file to be modified and the changes saved into the database.

The ability to edit an attached file is the most powerful feature of the embedded document tool. Any version of XMap 7 can be used to access files that are directly tied to their appropriate geographic location and additional information or notes can be added to the files right at the jobsite.

Distributing GIS Layers with Embedded Documents
XMap’s data synchronization function is a perfect complement to the embedded documents tool. Data synchronization provides a quick and efficient tool for distributing updated GIS layers throughout a company or organization. Because embedded documents reside in the OpenSpace database, these files are also synchronized—ensuring that the most up-to-date documents are available to those who need them most.

If a synchronized layer contains a document field, the recipient of the layer has the option to upload a file or edit an existing embedded document. As part of the subsequent synchronization process, the uploaded or updated file is automatically added to the central GIS database and is available to all XMap users in the company.

When an OpenSpace transfer file is created by exporting a GIS layer from XMap, any embedded documents that are associated with that layer are incorporated in the file and can be accessed when the file is imported by another XMap user. This process can be used to efficiently distribute geographically referenced files in situations where synchronization is not being used.

Using Embedded Documents with XMap Forms
XMap Forms, another new feature of XMap 7, provides a user-friendly mechanism for collecting or editing GIS layers and their accompanying attributes. If a form that includes a document field is created, the form provides buttons for uploading, deleting, and, if appropriate, editing the file. If an image is embedded, a thumbnail of the image itself is displayed in the form. Clicking this thumbnail opens an enlarged version of the image.

Document fields are compatible with forms created for use in XMap, but they cannot be used in a form created for the Earthmate PN-40, DeLorme’s handheld GPS receiver and data collector.

Embedded Documents at Work
In virtually all GIS applications, the embedded documents functionality in XMap offers a valuable supplement to the attribute management capability of the software and provides the means to manage files in the context of their geographic location. This allows convenient site-specific access to the documents that are associated with that particular location. Examples of embedded documents at work in specific industries include:

Oil and Gas
Attach pipeline maintenance reports to each pipeline segment. As each pipeline is inspected, the field technician can complete and automatically submit the report to comply with the necessary regulations.

Real Estate
Attach multiple building photographs to each property in the GIS layer. Add a field to attach detailed property specifications or information about comparable properties.

Natural Resource Management
Upload photographs to provide a visual context to data sampling locations in habitat or environmental impact studies. Using XMap Forms, click the GPS button to automatically create a new point and assign each photograph to the correct location.

One-call Administration
Assign a copy of a one-call ticket to each proposed dig location in a GIS layer. Automatically distribute the ticket to field crews using XMap’s synchronization tool.

Wind Energy Development
Embed detailed meteorological data pertaining to proposed wind farm sites. Upload a spreadsheet with details of the properties within a designated area of impact.

Surveying and Engineering
Upload scanned or digital copies of engineering blueprints and plans. Use XMap as a project management tool allowing efficient access to the appropriate sheets at each site of the project.

Utility Mapping
Embed detailed wiring diagrams at each junction location or utility access point. In the event of an emergency, the necessary repair information can be accessed by simply right-clicking at the current location on the map.

Delivery and Dispatch Management
Attach a copy of the shipping details to all delivery locations. At each site, right click the map to display the delivery list.

The enhanced embedded documents functionality in XMap 7 extends the attribute management capability to include complementary information in external files or documents. By offering the option to edit the contents of these associated files and allow the uploading of files in virtually any format, the data collection capability of XMap is limitless

Tab Tip—Using Duplicated Layers to Manage GIS Label Placement

February 23, 2010 by xmap

When assigning labels to objects in a GIS layer—whether the layer contains points, lines, or polygons—XMap’s integrated cartographic engine optimizes the placement of the labels to ensure the clearest possible text display while maintaining the aesthetic qualities of the map. Polygon labels are automatically placed at the geometric center of the object being labeled; point labels are, by default, positioned above and to the right of the symbol; and line labels are placed as close as possible to the mid-point of the line. If necessary, XMap uses a text decluttering process to ensure that one label does not overlay another.

In most cases, this automated labeling process is sufficient to clearly denote the required information about the object; however, cartographic sticklers will suggest that a perfect map cannot be created without some sort of human input. By following a few simple and creative steps, it is possible to fine-tune or tweak the positioning of labels in XMap while providing the opportunity to determine the zoom level range within which labels appear.

The first step in this process is to create a duplicate copy of the layer in question. To do this, first select the layer in the Workspace, click Layers, click Create, and then click Copy Layer. It is a good idea to add “Labels” to the name of this second layer.

Next, adjust the symbolization of this new labels layer so that the objects on the map are transparent or invisible. The Symbolize dialog box can be accessed by right-clicking the layer in the Workspace or by clicking the Tools button above the Workspace table and selecting Symbolize. For each color or class displayed in the Symbolization window, change the Opacity setting to Transparent, then click OK. The objects formerly displayed on the map will disappear.

You can now use the Label function, accessed from the Tools menu, to add the required labels to this transparent layer. Although the objects are not visible, the labels will appear on the map.

Initially, these labels will appear in the same location as if the original layer had been labeled; however, because the objects to which they are assigned are invisible, their position can be moved without affecting the appearance of the map. To move these labels, select the new labels layer from the Active Layer dropdown list in the toolbar and click the Edit tool to the right. Each label can be individually selected and moved as needed.

With the labels for the original layer now contained within a second layer, it is possible to more precisely control the appearance and behavior of these labels. To customize the settings for this layer, click the Tools button and select Properties. Within this dialog box are options for determining whether the labels appear in the Primary and/or Secondary Maps, for setting the Zoom Level range at which the labels appear, and for adjusting the layering hierarchy to ensure that the labels are displayed on top of the objects in the original layer.

With a little creativity, it is possible to create a map that not only uses the latest in cartographic technology but also allows a certain amount of individual input.

XMap at Work—Using the PN-40 GPS for GIS Data Collection

February 23, 2010 by xmap

One of the most significant new functions of the XMap 7 suite is XMap Forms. This innovative mobile GIS tool provides the opportunity for field technicians to view, edit, and collect GIS data using a laptop computer or an Earthmate PN-40 GPS receiver. After returning from the field, edits, additions, or other modifications can be automatically merged into an XMap GIS layer.

On the PN-40, XMap Forms functionality offers the ability to:

  • Record the location of field assets
  • Collect attribute data using preformatted drop-down lists, check boxes, and simple text entry
  • Verify the positional accuracy of current data layers
  • Modify the attributes for existing point locations
  • Move a point to a new set of coordinates
  • Delete existing points
  • Save collected data in GPX format
  • Store multiple forms, each containing their own data collection parameters for a variety of field applications

There are several considerations that should be addressed before deploying XMap Forms on the PN-40 for your mobile GIS operations:

  • To build an XMap form, you must have access to a copy of XMap 7 GIS Enterprise to create the requisite XMap 7 Enterprise database. XMap 7 GIS Editor includes the necessary tools for creating and managing forms, but not for creating the appropriately formatted database.
  • The PN-40s on which XMap Forms will be used should be upgraded to the latest Pro firmware.
  • The devices must be equipped with an SD card.
  • A GIS layer on which the form is built should be imported or created in the XMap 7 Enterprise database. Any data collected using a form is automatically appended to this layer.
  • It is not necessary to assign all attribute fields associated with a layer to a form.
  • Multiple PN-40s can be employed to collect data that is later integrated into a single GIS layer.
  • The process of merging collected data does not require each PN-40 to be connected to the host computer running XMap. There are several manual file transfer options that allow field-collected data to be submitted from a remote location.
  • Using XMap Forms on the PN-40 requires no additional forms license or locally installed software and the device itself requires no hardware upgrade.

Creating, Transferring, and Collecting Data on the PN-40 Using a Form

Step 1—Configuring a GIS Layer

As noted above, an XMap form is associated with a GIS layer in an XMap Enterprise database and therefore the first step in creating a form is to ensure the layer in question contains the required attribute fields. A form can be created using an imported GIS layer or a using a layer that is designed and developed in XMap specifically for this purpose. In either case, it will be necessary to establish certain field constraints to enable accurate and efficient data entry on the PN-40. Applying constraints to a field establishes limits on the data or values that can be entered when collecting or editing field information.

For an imported layer, the Attribute Design View in the GIS tab allows existing fields to be edited and constraints to be applied. To achieve this, simply right-click the attribute name in the Design View and click Edit Field. Depending on the data type, constraints can be applied that limit the number of characters that can be entered; that define an upper and lower range for the numeric values; or that specify a finite list of text entries that are acceptable. If an imported layer is pre-populated with existing points and attributes, the Suggest Values button will automatically create the list of value constraints based on what is currently contained in that field. This list can be manually supplemented with additional values if it is assumed that certain field-collected points will be attributed with data that is not included in the current list.

When creating a new layer for the purpose of collecting data on the PN-40, each field will be created manually. XMap 7 offers three options for creating fields:

  • Simple Field
    Use this option if you want manual text or number entry on the device without any constraints. Simple Field also offers the option to create a Boolean field which is manifested as a simple check box on the PN-40
  • Formula Field
    Formula fields, which are derived from a formula applied to an existing field, are not compatible with the PN-40 and cannot be used in a PN-40 form.
  • Constraint Field
    As noted above, this allows limits to be applied to the values that are added to a form. When creating a constraint field in a new layer, the Suggest Values button is not available as there are no preexisting values—therefore, the list of expected values must be manually typed. It is a good idea to include “Other” as a value constraint and to add a following simple text field to the form to allow text entry in the event that field observations do not match the constraints.

A Constraint Field can be assigned an initial value which will automatically be inserted with each new record. This option is usually applied if the vast majority of field-collected records have the same value and it eliminates redundant steps in the data collection process.

When symbolizing a layer from which a PN-40 form is created, be sure to use the Earthmate PN-Series symbol set. This ensures that the points displayed on the device will look the same as they do in XMap. If a layer is classified, all classes including the Null class must be assigned an Earthmate PN-Series symbol.

Step 2—Using XMap’s Form Builder

After the requisite GIS layer has been created and formatted with the necessary constraints, it’s time to build your XMap form. The form builder window is accessed in one of three ways: from the XMap Forms button in XMap’s toolbar; by right-clicking the appropriate layer in the Workspace and choosing Forms; or by clicking the Tools menu above the Workspace table and selecting Forms. Whichever method is chosen, click the Create option.

In the Create New Form window, there are several required steps for creating a form for the PN-40:

  • Enter a name for the form in the Form Name field. This is automatically populated with the name of the corresponding layer, but it can be edited if needed.
  • Change the Form Type dropdown to PN-compatible Form. XMap-only forms will not work on the PN-40.
  • If the PN-40 is being used to collect as well as view data, set the Form Operations selection to Add Data. Note that this setting will also allow points to be edited or deleted on the device.
  • If necessary, type a description for the form.
  • Under Attributes, add the fields you wish to include in the form using the arrow buttons and if required, adjust the order in which they appear.
  • To ensure that the correct Earthmate PN-Series symbols are assigned when points are displayed on the device, make sure you transfer the classification field to the form. This will be listed as a non-editable field.
  • To manually lock specific fields, ensuring the data cannot be deleted or modified, check the box next to the appropriate fields.

When creating a form for the PN-40, you may notice certain fields from your layer are not available in the attributes list. The reason for this is because certain types of data that are supported by XMap, such as document, URL, and currency fields, are not compatible with the device.

After all of the form parameters are set, click the Create button.

Step 3—Transferring a Form to the PN-40

A GIS point layer containing a PN-compatible form can be sent directly to a connected PN-40 from the Workspace in XMap’s GIS tab or it can be saved in a user-specified location and distributed via e-mail or manually copied to one or more SD cards. Simply right-click the layer name or choose the Send to PN-Series Device from the Tools menu to display the Export Points dialog box.

If the source layer contains existing data, these points along with their corresponding attributes will be copied to each PN-40 device that either directly or indirectly receives the form. If no preexisting data is present, such as in cases where the form is being used exclusively for data collection, an empty layer will be sent.

If the points and the form are being saved locally, two folders will be created at the specified location: a forms folder and a GPX folder. It is important that the recipient of these files replicates these folders on their SD card before inserting it into their device.

Another method for distributing XMap Forms to multiple PN-40 users is to use XMap’s data synchronization feature. This process transfers the entire source layer to a local version of XMap from where the form and data can be directly transferred to the device using the process described above. For more information on synchronization, refer to the XMap 7 Administration Guide.

Step 4—Collecting or Editing Data on the PN-40

The process of transferring the form and data to the PN-40, as described above, creates the necessary files on the SD card within the PN-40. Before using the form, these files must be loaded into the internal memory of the device. This process is initiated from the Waypoints screen on the device by clicking the MENU button, selecting File, and selecting Open. After choosing the appropriate layer, a list of existing points will be displayed in the Waypoints list. If the layer is empty a blank waypoint screen is displayed.

Collecting Data – To create a new point, press the Mark (pushpin) button at the bottom of the PN-40. The preconfigured form will be automatically displayed allowing the user to enter the appropriate data pertaining to that point. Use the arrow buttons to scroll between the available fields. When the form is complete, there is no need to save the point as it is automatically stored in the internal memory of the device. Instead, simply press the QUIT button to return to the previous screen or press the Mark button to create a new point.

Editing Data – To edit the attributes for an existing point, use the up or down arrows on the PN-40 to highlight the point in the Waypoints list and press the ENTER button on the device. Alternatively, move the cursor on the PN-40 screen to hover over the required waypoint and press the ENTER button. Initially, the attributes will be displayed as a read-only list. To enable editing, press the MENU button and select Edit Waypoint. All the attribute fields are now editable.

Deleting Points – Be careful when deleting points that were transferred to the PN-40 because when the data is later merged back into the source layer in XMap, the original point in the GIS layer will be deleted as well. To delete a point, select it from the Waypoints list or from the map as described above and press the ENTER button. After verifying from the attributes list that the point in question is no longer needed, press the MENU button again and select Delete Waypoint.

Moving Points – To move an existing point, enable the editing function as previously described and select the coordinates in the Position field. Note that these coordinates are assigned by the PN-40 and may not necessarily reflect the coordinates in the original data in XMap. After pressing the ENTER button, use the left and right arrow buttons to highlight each individual number in the coordinates and press the up and down arrows to adjust the values as needed.

After the data collection or editing process is complete, press the MENU button when displaying the Waypoints Page, select File and then Save. This copies the collected points back to the GPX file on the SD card in preparation for transfer into the original GIS layer in XMap. Note the same form can be used over again so there is no need to transfer a new version to the PN-40 for each data collection event.

Step 5—Transferring Field-Collected Data into XMap

The GPX file that was created when the form and accompanying points were transferred to the PN-40 retains its association with the original GIS layer so the process of merging collected data into XMap automatically adds the new points to the layer. Furthermore, any attribute edits or point deletions are also applied to the original layer.

To merge collected data, right-click the layer name in the Workspace in XMap or choose the Import from PN-Series Device from the Tools menu to display the Import from PN Series Device dialog box. The import process automatically recognizes the data layers on a connected PN-40 and displays the associated GIS layer for each data layer. This dialog box also offers the option to browse to another location if the GPX files have been emailed or manually transferred from remote PN-40 users.

To update the source layer with the new data, click the Merge button.

Employing XMap Forms functionality on the PN-40 significantly increases the value of the device by transforming it from a field data viewer into a fully functional GIS data collector. No comparably priced GPS receiver offers this level of functionality and provides access to such a wide variety of data at the jobsite, wherever that may be.

Tab Tip – Tracking Offenders with XMap’s GPS Radar Function

January 26, 2010 by xmap

November’s DeLorme Professional Newsletter included a list of the major functional enhancements in the newly released XMap 7 suite. If you read the entire article, towards the bottom of the list under the subheading, Other XMap Enhancements, you may have noticed “Improved GPS Radar Search”—a reference to a lesser known but, nonetheless, powerful component of the XMap toolkit.

About XMap 7

A recurring theme in the various descriptions of XMap is that it represents the perfect integration of GPS and GIS technology. DeLorme mapping software has included GPS functionality since its earliest days, when DeLorme was one of the first companies to introduce a GPS receiver for consumer use. It is no surprise, therefore, that when XMap was developed, it inherited a powerful set of GPS tools for tracking, navigation, data collection, and, as seen in the GPS radar functionality, proximity searching.

The idea behind the GPS Radar is very simple: if your GPS receiver is able to discern your precise location and the map on which your position is being displayed includes points of interest or other significant data layers, it is very easy to generate a list of these points that are within a defined distance and to update this list as you move. Originally, this functionality was incorporated into DeLorme software titles to help the traveler find particular businesses and services such as restaurants, hotels, and gas stations. However, it soon became clear that there could be many other applications for this tool.

One such example emerged during a meeting between members of DeLorme’s XMap team and a representative from a state law enforcement agency. The officer, citing studies indicating that most criminal activity is carried out by individuals who have been previously convicted, suggested that if each patrol vehicle were equipped with a system that would alert the officer when they came close to the address of a known offender, many crimes could be prevented. This discussion and other similar meetings, led to the development of a GIS-optimized version of the GPS Radar search function.

GPS Radar is a subtab of the Find tab in XMap and the set-up process involves a few simple steps:

  1. Create or import the GIS layer containing the points that you want to search for. If you are working with a database or a spreadsheet of addresses, XMap’s GIS import function will automatically geocode or assign each record the correct point on the map.
  2. Make sure you have a GPS receiver connected to your computer. If a device is not detected by XMap, the search will originate at the current map center.
  3. Click the Find tab and click the GPS Radar button.
  4. From the Find drop-down list, select either All GIS Points, which will return results from all active GIS point layers, or Custom, which provides a text box within which the name of a specific layer can be typed.
  5. Before beginning the search process, click the Options button to customize the behavior of the search:
    • Select the distance within which the search will be conducted.
    • Set the time between updates to the search results.
    • If required, choose the wording of the verbal prompt that is played when a result is found.
  6. Click the Search button to initiate the GPS Radar search. The results will be displayed in list form with the closest at the top of the list. After the previously determined time interval, a new list of results will be generated. Directions to the closest or selected object will be indicated by a thin green line on the map.

GPS Radar can be employed for a wide variety of applications; however, much of the new functionality was developed to address the specific needs of the mobile law enforcement community.

Utilizing GPS and GIS Technology for Emergency Management

January 26, 2010 by xmap

In recent years, there has been a surge in interest in location-based technology among organizations and agencies that would previously have considered these tools to be beyond their means. The emergence of low-cost and Web-based mapping applications and the ubiquitous availability of worldwide satellite-enabled navigation have instilled a spatial mindset within a broad cross-section of the population. Software offerings such as DeLorme’s XMap and GPS receivers such as the rugged Earthmate PN-40 are bringing this technology firmly down to earth.

The utilization of geographic intelligence has been particularly evident in the field of emergency management and response, where GPS technology has long played a critical role and where GIS—Geographic Information System—is now coming to the forefront. Response agencies at the national, regional, and local levels are learning that the efficient management of data plays a critical role in all aspects of emergency management, from mitigation to recovery.

Unlike in many other situations where the benefits of a GIS are measured in terms of increased efficiency, higher productivity, and ultimately dollars and cents, the benefit of this technology for emergency managers is that it saves lives. No matter what the situation, whether it is a major natural disaster, such as an earthquake, hurricane, or flood, or a local search and rescue operation, GIS can and should play a key role.

GIS Defined
While many GIS specialists might offer a more complex definition of their chosen field, the basic tenet of a GIS is fairly straightforward. A GIS is a system for managing data in its locational context. Typically, a GIS is a computer-based system for gathering, storing, organizing, and distributing location-based information.

Why GIS?
A well-organized GIS provides an invaluable tool for collecting data from a variety of sources, organizing it into a usable format, and efficiently redeploying the data to those who need it most. In the field of emergency management, a GIS can reduce response time, eliminate redundancy, streamline the allocation of personnel and resources, and can provide crucial information for planning future operations. Additionally, the common file formats in which GIS data is usually stored offer an easy means to share maps and data with other responding agencies.

Integrating GIS and GPS
It is frequently assumed that GIS and GPS are inherently connected; however, the interoperability of these two technologies is often a difficult process necessitating the conversion of files to allow the exchange of data from one platform to the other. Few handheld GPS receivers offer the option of  viewing GIS layers or aerial imagery, a feature which serves to extend the reach of the GIS infrastructure to remote locations. Nor do they typically provide the means to collect field observations that can be easily integrated into a centrally managed GIS. It was with this in mind that DeLorme developed the Earthmate PN-40, a GPS receiver that offers a unique set of capabilities.

Foremost is its ability to display map data from a wide variety of sources, including aerial imagery, USGS maps, NOAA charts, GIS layers, and more. Additionally, this waterproof device can be used to collect data using the innovative XMap Forms capability. This powerful component of the XMap suite utilizes customized drop-down lists, check boxes and simple text entry to not only mark a critical point but to record a wealth of invaluable information about the location. Back at the command post, the field-collected data from multiple PN-40s is integrated directly into a GIS layer, allowing emergency managers to quickly discern the spatial characteristics of the data and to make better operational decisions.

GIS for Emergency Management
Often the development of a GIS is approached as a three-phase effort: data collection, data processing, and data sharing. For emergency managers, much of the data collection and processing can be performed as part of the preparation work. A broad range of relevant data can be imported or created to reflect what might typically be required in an emergency within the jurisdiction of the responding agency.

When an emergency strikes, the GIS infrastructure needs to be flexible enough to work in the field and to incorporate all of the additional data that will be collected as part of the emergency operation. In such a dynamic and challenging setting, the system must be easy to manage and the data must be accessible to those with limited knowledge of GIS. An overly complex GIS requiring a specialist to run it may become an unwelcome bottleneck when the need for data and maps becomes critical.

Typically, GIS software is designed for office use; however, DeLorme’s XMap, which has been developed on the platform of the company’s renowned navigational software and includes route planning and GPS interoperability as standard features, has helped redefine GIS. XMap is equally at home in the office, in the vehicle, in the field, or wherever emergency operations are managed.

GIS and GPS for Search and Rescue Operations
When a hiker fails to show up at a designated rendezvous spot or a child goes missing after wandering away from a campsite, the local emergency response agency quickly steps up to the plate, often assisted by other organizations and willing volunteers. From the outset, a high degree of organization is essential.

Many searchers will be unfamiliar with the area so there is the risk of escalating the crisis if those who are searching becoming lost themselves. Others, eager to assist, may take it upon themselves to initiate a search without any collaboration with the agency in command and without access to potentially critical directions.

A GIS will allow the emergency manager to identify and record any currently available information: Where was the subject last seen? In which direction was he heading? What are the terrain, land cover, and natural vegetation in the proposed search area? Where are the best access points? With all of this information at hand, a strategy can be developed and a plan initiated.

A useful component of the GIS for both assigning response teams and keeping track of areas covered is a grid superimposed on the search area. By way of preparation, a custom floating grid can be created in XMap and dragged to the target area. For those responders who do not have access to a GPS device, a map displaying this grid along with all of the other pertinent information can be printed. Users of DeLorme’s PN-40 GPS receiver can have the same map sent directly to the device so as they proceed on their designated search path, they can see where they are in relation to the grid.

Upon returning to the command center, the track recorded by each GPS device is imported into XMap and overlaid on the grid to determine which areas have not yet been covered in the search. The GIS tools in XMap allow each track to be buffered creating a wider swath on the map so that a more realistic perspective of the actual area searched can be ascertained. XMap’s spatial querying and symbolization capabilities are then used to create an updated map that is then redeployed to each PN-40.

Classification or color-coding of the tracks is used to map the area searched by each team. For example, the track files that were recorded and downloaded from the GPS receiver used by the canine unit could be represented by a unique color, allowing the emergency manager to see where this particular team should be assigned next.

The collection of point-specific data is also important in the search and rescue effort. Tagging a location where evidence has been found is a simple process using the PN-40. A button on the device is used to create a labeled waypoint to which detailed comments can be added. As with tracks, this point data is easily integrated into a GIS layer allowing all of the information to be centrally managed and, if necessary, updated and redeployed.

If a photographic record is also appropriate, XMap includes a tool for automatically assigning a series of downloaded digital photographs to the precise point on the map at which they were taken. This geo-referenced photo can be displayed as a thumbnail image on the map or as a hyperlink, which opens the full size photograph.

For emergency managers, the application of GIS does not end with the completion of the search operation. All of the data that has been collected during the rescue effort can be reviewed and analyzed to help plan and prepare for future events. It can also be used to create simulations for the purpose of training other responding agencies.

Conclusion
A GIS is a tool that manages information to enable better decision-making and nowhere is the decision-making process more important than in emergency management and response. Among the critical considerations when deciding to apply spatial technology for emergency management and response are the flexibility and suitability of the system for field applications, the accessibility of the technology for novice-GIS users, the interoperability with other applications and data sources, and the ability to efficiently share data with handheld GPS receivers.

XMap GIS software and accompanying Earthmate PN-40 GPS receiver from DeLorme meet all of these requirements and collectively provide a perfect mapping and GPS platform for all emergency operations.

DeLorme Responds to Haiti Disaster

January 26, 2010 by xmap

A few weeks ago, the XMap team met to discuss the content of January’s edition of the DeLorme Professional Newsletter. It was decided during the meeting that we would focus on the application of XMap and the Earthmate® PN-40 GPS receiver for emergency management. Little did we know at the time that within a few days the nation of Haiti would fall victim to one of the most devastating national disasters in living memory and that DeLorme mapping and GPS tools would be quickly called into service.

As the news of the severity of the earthquake filtered out, and agencies and organizations from around the world mobilized to help the citizens of this already impoverished country, calls started to come in to DeLorme requesting accurate and up-to-date map data as well as assistance deploying our software and GPS products. DeLorme data technicians quickly responded and developed a GPS-accurate, routable road and street map for Port-au-Prince and other affected areas for use in XMap and on the PN-40.

XMap Q & A – Will XMap or the PN-40 work outside the U.S.?

December 14, 2009 by xmap

There is no technical limitation that restricts the use of XMap or the Earthmate PN- 40 GPS receiver to use in the United States. Courtesy of the United States Department of Defense, a reliable GPS signal can be used to establish a precise positional fix virtually anywhere on the surface of the planet at any time. XMap and the PN-40 can therefore be used to monitor location, track movement, and accurately create waypoints or other draw objects no matter where in the world you are located.

In practical terms, however, the most significant impediment to using DeLorme mapping technology outside of the U.S. has, until recently, been the availability of map datasets. This barrier is slowly disintegrating and there are now several avenues for non-U.S. XMap users to view, import, or create base map data:

  • XMap World Base Map
    Skilled cartographers at DeLorme recently embarked on an ambitious project to create the first seamless, consistent, accurate, and up-to-date base map for the entire world. This effort culminated in the XMap World Base Map, a vector-based dataset incorporating an extensive GPS-navigable road network, geographic and hydrographic features, land cover information, elevation, and much more. For information on purchasing this dataset, call 1-800-293-2389, or e-mail prosales@delorme.com.
  • Locally Available GIS data
    GIS professionals within the U.S. have access to countless data libraries and archives from which thousands of data layers, both raster and vector, can be downloaded, usually at no charge. Such publicly accessible data repositories are becoming increasingly common throughout the rest of world as government agencies and educational institutions recognize the value in encouraging the application of spatial technology. In these archives, XMap users can usually find compatible data in the form of shapefiles, GeoTIFFs, or other common GIS formats.
  • Scanned and Registered Paper Maps
    Often considered a last resort if no preexisting datasets are available, the ImageReg function in XMap provides a straightforward means to convert a standard image file into a raster GIS layer. The obvious benefit of this approach is that any local map or aerial image that is either in a standard image file format or that can be scanned is compatible. The positional accuracy of the final dataset depends on the precision with which the anchor coordinate points are established and, obviously, on the accuracy of the original map itself.
  • Canadian Topographic Maps from the Map Library
    If your foray into foreign lands takes you no further than our neighbors to the north, XMap has you covered. The Map Library subscription now includes unlimited downloads of Canadian topographic maps derived from the 1:50,000 series. These high-quality maps are available from the U.S. border to beyond the Arctic Circle.
  • XMap’s Embedded Reference Data
    If you have ever clicked the pan button in XMap a few too many times or imported a coordinate dataset without first checking to see if the longitude values had the requisite minus sign or West designation, you may have found yourself, or at least your map view, in some remote corner of the world. You may also have noticed that the map is not blank, at least up to zoom level 6. Embedded in all versions of XMap is worldwide Reference Dataset that, while not detailed enough to allow you to plan a hike in the Himalayas, will, with the aid of an attached GPS, let you know if you are currently in Kathmandu or Khartoum.

XMap users within the U.S. have become accustomed to the integrated high-quality topographic and street level datasets that are the foundation upon which XMap projects are built. Not only does DeLorme design and develop the software, we also create and manage the map datasets themselves; a truly unique amalgamation of spatial technologies. With the release of the XMap World Base Map, this synthesis of maps and software is now available worldwide, supplemented by locally available GIS layers and other data. XMap and the Earthmate PN-40 are therefore truly global mapping tools.
