Best regards,
My company has purchased several licenses and need to know how do I upload a geoid model for Colombia from this software.
I appreciate your prompt attention and response,
Marvick Ruíz
Dear Marvick,
Using geoids it's quite simple. Check Settings>GNSS panel, and tap this button:

Select your geoid you would like to use.
Supported geoid file formats:
•.DAT files
•.BIN files
•.GSF files
•.GGF files
•.GEO files
