GEOID18 Height and Estimated Uncertainty for GPS on Bench Marks dataset used to create GEOID18 (NCEI Accession 0209231)

Description

This file contains a list of geodetic bench marks, identified by a Permanent Identifier (PID), each of which have a precise orthometric height determined by geodetic leveling, a precise ellipsoid height determined by GPS surveying, and a precise modeled hybrid geoid height. The observations were used to constrain a gravimetric geoid model to the surface of a current vertical datum to produce a hybrid geoid model and associated performance metrics. The data is primarily from the US, however some data from Canada and Mexico is included as well.
