GIS Basics

Why Use GIS?


GIS is a powerful tool for analyzing and mapping geographic data.   As mentioned above it is the combination of database operations (query, selection) and visualization tools that makes a GIS unique. 


Prior to GIS the development of GIS, it was extremely difficult to perfom queries that involved more than one or two layers of data.  The modern GIS makes it possible to quickly and easily query multiple layers of data and display the results in a thematic map or tabular report.  Whether you are a farmer and you want to find the best soil for growing corn, finding the best route for an emergency vehicle, or a realtor finding a house with three bedrooms, a GIS provides the tools to ask questions, explain events, visualize scenarios, planning strategies, to name a few.
