Example of Data Layers in GIS What is a GIS?
A geographic information system (GIS) is a computer-based tool that combines the visual appeal of conventional maps with database operations and statistical analysis. It is used for mapping and analyzing things that exist and happen on the surface of the Earth by classifying the information into “layers”, making it easy for users to distinguish each element separately. The speed and accuracy of a GIS provide an invaluable service to organizations, such as the City of Rockville, by explaining events, predicting outcomes and planning future strategies.
