What is a Geographic Information System?

A Geographic Information System (GIS) displays geographically-referenced information in the form of electronic map displays. 

• Map data appears in the form of various

  data layers

  (e.g. Buildings, Roads, Parcels), many of which can be queried for more detail. 
• Map

  layouts

  can be modified to suit your needs by panning and zooming to the appropriate extent, and turning layers on and off as you please.
• You may

  print your own map

  layout from the online map; you may also view and/or print various prepared maps.
