Converting .gsb (binary file) to .ggf (GEOID Models) for Trimble Access
Hello everyone,
There is a geoid model in its early stages that’s been released in .gsb format by the national authority. It is released as a binary file. I wanted to do some testing to check its behavior agaisnt current geoid model and some other projects where I’ve got good level data.
I tried bringing it in the TSC7 however, it recognized it as invalid geoid model.
My understanding is Trimble Access only takes in .ggf file. I tried Trimble Grid Factory. But it does not have the Reference Ellipsoid I was after. I believe it was slightly changed version of GRS80 that was done in 2020.
Do you happen to have some experience in .gsb to .ggf conversion process?
Any appreciate any guidance in the matter.
Regards.
