What is GIS?

GIS stands for Geographical Information Systems. The official definition of GIS is an advanced computer system capable of collecting, storing, viewing, and analyzing geographically referenced or spatial information. 'Geographically Referenced' or 'Spatial' simply means that the information can be viewed on a map and analyzed based on location and proximity. Examples of mapped places can  include an address, a property parcel, a named place such as a park or neighborhood, a census block, a zip code, or a city. By taking information stored in spreadsheets & tabular databases and displaying & analyzing it on a map, a GIS becomes a powerful tool.
