Geodetic Control Technical Work Group


The Geodetic Control Theme provides the horizontal and vertical positional underpinnings for all spatial datasets in Idaho.


The current focus of the GC-TWG is the real-time correction network, the multistate control point database (MCPD) and working with the National Geodetic Survey (NGS) to develop a revised spatial reference system for Idaho as a result of NATRF2022. 


  • Promote the use of the Control Point Database. This includes promoting people to use the data, but also promoting contributions of new surveyed control points to the database.
  • Continue working with the National Geodetic Survey on the modernization of spatial reference systems for Idaho.
  • Continued collaboration with The Utah Reference Network to provide real time GNSS corrections for Idaho
