Welcome to the California Geographic Information Systems (GIS) web portal.  The California Mapping Coordinating Committee (CMCC) is in the process of developing a series of GIS-related web pages to provide information on State government GIS activities, access to statewide GIS data, and links to the larger California GIS community.  This website and the Spatial Information Library are works in progress.

Starting July 1, 2001 some of California's physical and cultural geospatial information, formerly distributed by the Teale Data Center, is being distributed to the public by the California Mapping Coordinating Committee through servers at the California Environmental Resources Evaluation System (CERES) in the Resources Agency and National Aeronautics and Space Administration (NASA) Ames Research Center.

Note: CMCC will be working to update and improve some of the spatial data in the library and provide access or links to more up-to-date data served by others over the next several years as need and funding permit.  Caution should be exercised when using some of the layers of data as they are somewhat outdated; particularly those datasets that change rapidly (i.e., schools, health facilities, etc.).  We strongly recommend that users refer to the metadata or information about GIS datasets for appropriate uses of the data, source information, scale information, and general quality.

CMCC would like to acknowledge the support of the Executive Sponsors in the Resources Agency, Department of Information Technology, California Environmental Protection Agency, Governor's Office of Planning and Research, and Health and Human Services Agency.

We would also like to gratefully acknowledge NASA's funding support for CaSIL under Cooperative Agreement Notice 97-MTPE-02.
