WHAT IS GIS?
Geographic information describes the locations of features on the Earth’s surface. A geographic information system (GIS) is any system which displays geographic features with related tabular data to allow a user to organize, map and analyze data in a geographic or spatial way.

Typically, a GIS can analyze spatial data and visualize results in the form of maps, reports and charts
