Mapping FAQs

Q: What is GIS?

GIS is an information system that allows data to be analyzed spatially. GIS links graphic features (subdivision lot) with non-graphic data (a record in a database that stores owner information, sale date, assessed value, etc…). In a GIS, spatial relationships between map features can be analyzed such as which lots are within 300 feet of a selected lot. Also, spatial relationships can be created by overlaying multiple layers to answer questions like:

  • What fire and police jurisdiction is a location in?
  • Is the location in an area prone to flooding?
  • What land use and zoning is allowed at a location?
  • What day is the trash and garbage picked up at a location?  

Q: What GIS software does the City use?

We use ArcGIS by ESRI.
