FAQ
GGF to FLIF 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 FLIF files?
FLIF (Free Lossless Image Format) is a royalty-free format launched at the end of 2015 as "work in progress" with the aim of offering a better alternative for storing lossless images than the existing PNG, WebP, BPG, JPEG2000 and JPEG XR. FLIF provides similar image quality as the other extensions, but in a file size than can be up to 74% smaller. The new format uses a form of the Adam7 algorithm for compressing images, offering progressive interlacing that allows users to obtain a reasonable encoding of an image even from a partial download.
