Land Survey Program
Height Modernization Survey
Volunteers Are Needed for Missouri's Height Modernization Project
The Height Modernization presents a unique opportunity for GPS users to upgrade and densify their local geodetic control network.
What is Required?
Observe Height Modernization stations for a period of time. The time period will be determined according to the benchmark you recover in your county.
Use geodetic quality dual-frequency receivers with National Geodetic Survey (NGS) "calibrated" antennas and calibrated fixed-height tripods.
Submit vertical mark recovery form, satellite visibility obstruction diagram and updated descriptions to your State Project Coordinator.
How Do I Start?
