This issue could be debated at length and the response will likely vary depending on who is being asked. Before proceeding, it is worthwhile that we first come up with an explanation for the phrase Geographic Information System. By individually considering the three components of the term, we can create a clear and concise definition.
The word Geographic obviously
means that it relates to location; Information tells us that there is some sort of data related to that location; and, finally, System implies that we are dealing with more than just a map or even mapping software—but, rather, a multi-faceted process that allows us to consider the data in the context of its location. Therefore, a GIS is simply a system for analyzing information as it relates to location.
So can it be argued that a map generated using the Draw tools in XMap or any other DeLorme software is a GIS? Certainly the Draw tab provides a variety of tools placing points, lines, and polygons on the map and for customizing the symbolization of each object. What’s missing is the ability to assign data or attributes to these objects. The flag on the map might convey to the viewer that there is an item of interest at that location, but it will not paint the complete picture by offering access to the relevant data about that item.
In most cases, the step up from simple mapping to a fully-fledged GIS is fairly straightforward. If you have already taken the time to create a draw layer that shows the location of your data objects, you are halfway there. All you need to do is import the draw layer into the GIS tab in XMap, then either manually add as many different attribute fields as you need or, better yet, import and link existing data in such formats as Microsoft® Excel, Access, or even text, and then automatically assign each row of data to the appropriate point.
Before long, you will realize the benefit of having your data geographically assigned in this way. Through processes such as classification and querying, you will be able to discern patterns in your data that would otherwise have gone unnoticed. Furthermore, data stored in a GIS format can be easily shared through a common database connection, within which permission settings will allow varying levels of access. This helps ensure that everyone in your organization has the latest versions of your data.
