GIS: A way to understand how data changes from place to place
If the things you study or teach change from place to place, you could find Geographic Information Systems (GIS) software useful.
Nearly everything changes across the landscape: people; their businesses, income, and health; ecology, and even chemistry.
GIS hooks a database to a mapping system so you can make maps of geographically changing information. This presentation introduces ArcGIS, a standard GIS package now available campuswide. With it, you can create maps to allow people to interpret and manipulate data. This includes showing how one data type connects to others (e.g., census data, crime, and neighborhoods). This software is used by businesses to determine where prospective customers might be. It is used by governments to link the streets and water departments so roads are paved after new water pipes are installed, not before. And it is used by academics for all kinds of scholarly investigations.
