Geodetic Control Data Standard

Purpose

These standards establish and reference Geodetic Control Data Standards for vertical datum, horizontal datum, and the state's coordinate system used for agency geospatial data, geographic information systems, and data exchanges.

They are designed to improve data quality and accuracy, and simplify the exchange of geodetic control data among state agencies, local, tribal, state, and federal users and producers.
