How will I validate the precision/accuracy of my heights when I use a GPS/geoid approach?
The stations from the federal Canadian Base Network (CBN) and provincial High Precision Network (HPN) can be used by stakeholders to validate GPS/geoid procedure for the determination of accurate 3D positions. In addition, several benchmarks have 3D positions; however, the quality of these 3D positions may vary depending on the GPS epoch of observations. Also, one has to be careful about the stability of the benchmarks.
