City of Santa Rosa GIS Information

Welcome to the City of Santa Rosa Geographic Information System (GIS) About page.

The GIS Services Section provides coordination, support and maintenance of the City's GIS system and GIS services for all departments. The City GIS group also works closely with Sonoma County GIS to support county-wide 911 dispatch. The GIS system is accessible by all employees on the intranet and by citizens on the internet.

Here you will find interactive maps for the City and County that allow you to zoom in and out, control which GIS layers are displayed and get various kinds of information through map tips and reports. These maps can be downloaded to your PC and printed. Additionally, you can get information about other GIS services provided by the City of Santa Rosa.
