    What is GIS?
    A collection of computer hardware, software, and geographic data for capturing, storing, updating, manipulating, analyzing, and displaying​ all forms of geographically referenced information; i.e., data identified according to their locations (latitude/longitude, state plane coordinates, etc.). GIS combines geography with system information. In simple terms, it is a map linked to a database.
