What is GIS?

According to GIS.com

    "A geographic information system (GIS) integrates hardware, software, and data for capturing, managing, analyzing, and displaying all forms of geographically referenced information."

Most people recognize the maps that this system produces, like this one of Clark County.


But, GISMO's mission is much more than just map making.
