Cedar Park GPS survey monuments are documented on individual data sheets including photographs showing their locations. All monuments are referenced to the North American Datum of 1983 (NAD83), using the High Accuracy Reference Network of 1993, (HARN). The vertical datum is referenced to the North American Vertical datum of 1988 (NAVD88) using the Geoid 99.
Existing monuments, established in 1999 and 2001, are monumented with 3” brass disks set in concrete. Four more recent monuments are monumented with 3” aluminum disks set in concrete.
Links for monuments that have been damaged are removed from the map and data sheets.
