Geographic Information Systems

Doug Polzoni

This Section of the County Website represents the ongoing work of the Calaveras County GIS Committee to develop a more efficient and user friendly system for accessing and distributing County information. 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. This joint effort has been formalized in the form of a Memorandum of Understanding (MOU), signed by each of these four participants. The MOU outlines an agreement between the participants to share GIS data openly.

Virtually all of the information gathered and used by the county can benefit by being linked to spatial data. The GIS will further be used to distribute the county datasets to the general public within the constructs of the MOU.
