Microsoft has added Internet Explorer, Version 8 to the files included in automated Windows updates.  This version has a new feature titled 'Compatibility View,' that is needed to view the interactive maps available on this page. Instructions for using this view are here.

At the request of the community college research community, a map has been added showing overlapping land areas for California Community College Districts and Counties.  While viewing the map, click the copyright for sources and additional notes

Additional data layers, such as roads and waterways, have been excluded to improve refresh rates. However, others maps on the left side of this page, do provide these details.

An updated interactive map of H1N1 (swine flu) infection rates is available.  The map is focused on California, but users can zoom in or out to view world-wide or local views.  This map is made possible by the Flu Tracker.

To help community college users explore the overlapping patterns of regional college enrollments, population and population growth and employment patters, three interactive maps are now avaiable. 

As you explore your college district, remember to use in the "i" (information) icon to view tabular data for the top-most map layer.  To view data for a specific layer, turn off (remove the check mark) for any layers above the layer of interest.  The information command will return data for the next map region checked. 

To tally multiple groups of table data, select 'Add to Results,' and the data details will be collected in the top of the table of contents, found on the left side of the map.

The Regions and Land Use interactive map includes the square miles for all college districts, two different district regional systems used by the California Community College Chancellor's Office, legislative districts, county boundaries, K-12 districts and urban areas.  With so many layers, this first version can take several seconds to load, but by keeping these layers together in a single map, users can easily assess the overlap of these regions with the community college districts. 

For the first time, a state wide set of California community college campus polygons are available for viewing and for download (see Documents page).  The campus area maps are draft status.  Review and comment from the community college research and GIS community is encouraged. 

The campus polygons were used to calculate geometric centroids for each campus, and these centroids replace previous campus point data that was based on an address look up that was not accurate for all campuses when viewed at street level.  Included in the revision is a correction to the Campus ID (CID) number for the College of San Mateo: CID=372 not 472 as previously reported.

Finally, this update includes two corrections to the college district boundary maps.  The district names of Ohlone and Gavilan were transposed.  These districts are now shown correctly, with Ohlone Community College District (CCD) being north of Gavilan CCD.
