FAQ
GGF to IFF Conversion
What are GGF files?
GGF is the Trimble Grid File, a binary format that stores a geoid model as a regular grid of values. Geoid heights describe the separation between the reference ellipsoid used by GNSS receivers and mean sea level, so a GGF file lets Trimble field and office software convert ellipsoidal heights from satellite measurements into elevations above sea level. Each file represents one geoid model, such as a national or regional model, and the right file is chosen according to the geoid defined in the project's coordinate system. Files can be large, and Trimble Business Center offers to cut a smaller sub-grid for the survey area before sending a file to a field device.
What are IFF files?
IFF is an old image format associated with Amiga computers — a brand connected to Commodore, which used to be popular in the 1980s and 1990s. Commodore was one of the first types of personal computers to gain wide popularity among home users. An IFF file most likely contains an image that was created or edited using an image handling program on an Amiga computer. IFF files are currently considered obsolete and uncommon, so opening them with regular image viewers might be difficult.
