Unit: metre

Geodetic CRS: NAD83(2011)

Datum: NAD83 (National Spatial Reference System 2011)

Ellipsoid: GRS 1980

Prime meridian: Greenwich

Data source: OGP

Information source: San Francisco Enterprise GIS Program, Department of Technology, City and County of San Francisco.

Revision date: 2015-06-15

Scope: Ground coordinate reference system for support of general survey activities, GIS, and for measuring annual and episodic earth movements in and around city and county of San Francisco.

Remarks: Designed for mm precision in city and county of San Francisco, adequate for cm precision for GIS use in 10-county area. State law defines use of US survey feet. See CRS code 7132 for equivalent non-metric definition.

Area of use: United States (USA) - California - San Francisco bay area – counties of Alameda, Contra Costa, Marin, Napa, San Francisco, San Mateo, Santa Clara, Santa Cruz, Solano and Sonoma.

Coordinate system: Cartesian 2D CS. Axes: easting, northing (X,Y). Orientations: east, north. UoM: m.
