Enabling Deprecated Geoids

Posted on May 27, 2016June 3, 2016 by GeoCue Support

When updated Geoid models are released by NGS, GeoCue is updated to reflect these changes. The previous geoids still exist within the program, they are however disabled. We do this because NGS states for example that, “When using the geoid models, please be advised that GEOID12B should supersede previous models GEOID12 and GEOID12A.” If there…

CueTip – Adding a New Geoid Model in GeoCue

Posted on January 15, 2015May 27, 2016 by GeoCue Support

Geoid models in GeoCue are grid-based. The required file format is simply a rectangular grid of geoid undulation values, N, where h = H+N, with h representing the ellipsoid height and H the geoid height. The grid contains only undulation values. The grid points are required to be at regular geographic intervals in latitude and…
