What is GIS?

A geographic information system (GIS) is made up of computer models or "maps" and the tools that are designed to analyze them. With a GIS, you can view and analyze a map by studying its different "layers". In the “old times” you could do this with transparencies, by stacking transparencies together (1 layer = 1 transparency). Today, each transparency is replaced by a digital layer and you can superimpose these layers as you wish, using GIS software. GIS thus allows you to study relationships between different layers and detect relationships between different variables. Although transparencies were great for their time, GIS can do so much more. For example, with the help of GIS, you can create dynamic maps that show change over time, you can calculate the shortest path in between points, and you can create predictive models. GIS has been used in many industries for decision-making and policy formulation. It has been prominent in the environmental and agricultural sector (how does climate change affect crops?), but has recently flourished in the business sector (where to open a new bakery?) and is rapidly expanding into new sectors such as conflict management (crisis mapping). Many organizations such as the World Bank, the World Resources Institute, and the US State Department use GIS for analysis and policy design.

GIS Software

RSG supports ArcGIS and Google Earth, two of the most popular GIS programs on the market. We can also assist you with spatial analysis using other programs such as STATA, ArcGIS and Google Earth. Please attend our workshops or contact RSG to schedule a one-on-one tutorial, which can be customized to your research needs. RSG trainers can also visit your class to lead an in-class introduction tutorial for students. To request fill out an in-class tutorial form.

In addition ArcGIS is available to all members of the campus community through our Virtual Computing Lab. More training materials can be found here.

 

Collegial Networking: GIS User Group

RSG organizes a group of AU faculty who have an interest in and/or experience using GIS and who want to share their knowledge. This group will occasionally meet to brainstorm events, identify needs, discuss their research projects and create resources to enhance GIS scholarship at AU. If you are interested in joining, please email rsg@american.edu.
