California County Information Services Directors Association awards Calaveras County GIS the 2019 Innovation Award for the development of the Emergency Public Evacuation Application. Congratulations Doug & Dan!


Who We Are

The GIS Project was started through the cooperative effort of The City of Angels Camp, The Calaveras County Water District, The Calaveras Council of Governments, and the County of Calaveras.  GIS is also used to distribute the county datasets to the general public.

What We Do

This Section of the County Website represents the ongoing work of the Calaveras County GIS Department to develop a more efficient and user friendly system for accessing and distributing County GIS information. We invite all to search and explore the Open Data Portal and engage with our data to create innovative solutions.
