Notes about the GGF file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries, unused processes and other unfavourable system settings to identify slowdown issues.
The GGF file type is primarily associated with 'GPS Pathfinder Office' by Trinble Navigation Limited. The GPS Pathfinder Office software enables you to pre-plan field sessions. The data dictionary editor creates custom pick-lists, automatic repeat feature, and numeric values. In the field, the data dictionary prompts the field crew to enter specific information for data integrity and compatibility with your GIS or database. A geoid model is a mathematical definition of the difference between WGS-84 Height and local height above mean sea level (MSL). It defines the mean sea level over a local area. A geoid grid model is a file that contains these differences for a number of positions on a grid.
