Base Survey Control Benchmarks

 

10 Locations, Virginia, New Jersey, Massachusetts, Maine, Rhode Island

DuBois & King’s survey team established base survey control benchmarks for the monitoring of SMIA (Salt Marsh Integrity Assessment) sites. The project’s objective is to identify existing and establish new geodetic survey benchmarks that are all defined by the same relative elevation datum. The benchmarks were established at 10 national wildlife refuges in the states of Virginia, New Jersey, Connecticut, Rhode Island, Massachusetts, and Maine.
