Station Report

Geoid velocity added

To correct for the vertical drift between reference frames, the velocity of the geoid height (VN) is now calculated and incorporated into the calculation of the orthometric height. View documentation to learn more.

Station Coordinates

Unless otherwise noted, all displayed uncertainties are computed at the 68% (1-sigma) confidence level.

Changing these fields will auto-update the station coordinate information below.

The velocities are interpolated from the national Velocity Grid version 8.0.
