The map to the left is organized by Caltrans Districts.

The table below organizes geodetic control stations by Caltrans district, then by county. You can access a Google Earth kml, or download a zipped file of either a shapefile set or a kml file. Shapefiles are viewable in ArcGIS or AutoCAD; you need to have GE on your computer to view kml's. (The GE file might need to be downloaded and unzipped in order for our symbology to display properly.)

If you would like to create a spreadsheet containing attribute information, utilize this cheat sheet. Read key to CA control stations to understand how shapefiles are named and coded.

To understand how shapefiles are grouped within each county, see cheat_sheet_4_control_retrievals.txt
