Geospatial Standards

Geodetic Control Theme Definition: Survey control points or other related datasets which are accurately tied to the National Spatial Reference System, a common system for establishing coordinates for geospatial data that are consistent nationwide. Examples include: (1) benchmarks, (2) triangulation or GPS survey stations (3) data from Global Navigation Satellite Systems (e.g., GPS), (4) gravity measurements, and (5) models of the earth's gravity field (geoid).
