GIS, IMS and Other Mapping Resources

Geographic Information Systems (GIS) enable one to analyze spatial data in many different ways, although the learning curve for this software can be quite steep. Internet Mapping Services, while readily providing maps through an easy-to-use web interface, can be somewhat limited in terms of what's available and how the information can be used. How does one know what one needs?

First, look at some innovative uses of maps and curricular ideas to get started thinking about how to incorporate maps and mapping tools into your classes.

Next, check out a few map collections and specialized tools to see more of what can be done with maps and mapping.

Get your imagination going with "50 Things to do with Google Maps" or "50 MORE Things to do with Google Maps" (both from the blog Google Maps Mania).

If you're thinking, "I need of map of ...", then an Internet Mapping Service might fill your need just fine.

There are services for national and international mapping resources. Many federal, state and local government agencies provide mapping services which allow access to public data. Some NGOs and instructional sites also provide excellent resources. Most sites include a tutorial or "Getting Started" page that will show you most of the site's features in a very short period of time.

If you're thinking, "I just need to plot some locations ...", then you may be able to create a "mash-up" with Google Maps or Google Earth.

Here's a page of Google resources, including information on how to combine your own data with Google Maps or Google Earth.

Another possibility is MapServer, an open-source development environment for building spatially-enabled internet applications.

If you're thinking, "I have some data I need to analyze ...", then you are probably looking for a Geographic Information System.

There are a number of different GIS applications, such as ArcGIS, MapInfo, Idrisi, and others. All of these applications allow the importation or creation of geospatial data, the analysis of this data using various techniques (such as buffering or hillshade), and the layout of professional-quality maps. Learning how to use these applications will require many hours of instruction, however, so make sure that you really need these tools. For further information about GIS or using mapping resources in class, please contact course-support@hamilton.edu, or call 4877.
