LEGISLATIVE COUNSEL'S DIGEST

SB 566, as introduced, Jones. Geodetic datums and spatial reference network.

Existing law defines the official geodetic datums and spatial reference network for use within this state for purposes of surveying and mapping, including the North American Datum of 1983 and the North American Vertical Datum of 1988.
