Geodetic Utilities

The geodetic utilities below provide supporting information associated with geodetic postioning.

Plate Motion Calculator

The Plate Motion Calculator calculates rigid plate motions at one or more specified locations on Earth using one or more plate motion models such as ITRF2020 (2023), GEODVEL (2010), MORVEL (2010), and so on to earlier models such as NUVEL 1 and 1A. The user can additionally override and select the tectonic plate of attributed motion or the user's own Euler vector motion and/or select the reference (e.g. NNR, or a specific tectonic plate, or the user's own Euler vector reference)

Geoid Height Calculator

The Geoid Height Calculator calculates the geoid height correction at one or more specified locations on Earth using the EGM96 gravity model.
