Release Name: cahn-1996

Notes: The 'HIGHPRECGNET' layer represents the locations of high precision geodetic control points in California. Because this is a GIS repre- sentation of real-world points, users should keep in mind that it is the points themselves which are located very accurately, not the GIS representations of them. The quality of the placement of points in a GIS model depends on the quality of the mathematical routines that are used to project, store and display coordinates. These data have been converted to an Arc/INFO coverage using generate; then projected from latitude/longitude (NAD83) to an Albers meters (NAD27) coordinate system. Before generate was used, the coordinates were converted to decimal degrees from DMS.dd format.
