GIS and GPS

• What is GIS and how does the City of Brentwood use it?

  A geographic information system (“GIS”) integrates computer hardware, software and data for capturing, managing, analyzing and displaying all forms of geographically referenced information. GIS helps us visualize, question, analyze, interpret and understand data to reveal relationships, patterns and trends. The City of Brentwood uses GIS to notify the public, track City-owned assets, map service areas and service days and more. GIS also allows staff to track asset maintenance and respond to requests for service more efficiently. Having a robust GIS also allows staff to print high-quality, accurate maps that help City leaders make informed decisions.

• What is GPS?

  GPS is an acronym for Global Positioning System, a worldwide radio navigation system formed from a constellation of 24 satellites and their ground stations. GPS interacts with these satellites as reference points to calculate positions, which become data that can be used by GIS.
