There are several reasons that a point cloud or ortho data may not align with checkpoints to the expected accuracy. Below is a list of common reasons that this might occur. Base station position In PPK processing, the base station position, antenna height and antenna calibration file must be correct. Please review the Base Station…
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…
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…
