Open Data Portals

The County of Sonoma supports the Open Government Initiative and is undertaking its own strategic initiative to make GIS data accessible to citizens. ISD GIS is utilizing standards developed by the Open Geospatial Consortium (OGC) to support interoperable solutions that "geo-enable" the web.

ISD GIS is implementing a pilot program for Open Data using Socrata and Esri Open Data. The program is in the early stages of development so check back frequently for updates.

PRMD GIS Data Download

The County of Sonoma Permits and Resource Management Department (PRMD) maintains additional GIS datasets which are available to download from their site. You can also view the data interactively with the ActiveMap web mapping application.

PRMD GIS provides the ability to download geographical datasets. The PRMD GIS information should be used for planning and design purposes only. The geographical information should not be used for emergency services, engineering purposes, relied upon for survey control, or used as a legal document.
