  • What grid formats does WorksManager support? WorksManager supports geoid grids (.ggf file format),  datum grids (.dgf), shift grids (.sgf), and snake grids (.dat)


  • Can I add multiple grid files? Yes, you can add any combination of these grid files. You can add upto a max. of 3 files. Few examples below...
    • .ggf + .dat
    • .ggf + .dgf 1 + .dgf 2
    • .ggf + .sgf etc.


  • Does WorksManager extract the grid information from the calibration file and add automatically?  No! WorksManager does not extract the grid information automatically. The user has to add the grid files separately from the product in addition to the calibration file. 


  • Will these grid files be available in TCC? Yes, absolutely. The grid files  will be available in these folders in TCC
    • Earthworks: Project Library -> GeoData
    • Siteworks: Trimble Synchronizer Data -> <Device> -> Trimble GeoData
    • GCS900: Trimble Synchronizer Data -> <Device> -> Machine Control Data -> GeoData
    • SCS900: Trimble Synchronizer Data -> <Device> -> Trimble GeoData


  • When I edit/ delete grid files from a specific project in WorksManager, will they be removed from TCC? No, while they get removed from the WorksManager project settings, they will still be available in TCC. This is because ‘GeoData’ is designed as a common folder across projects in TCC. While this project might not want the files, another project might still need them.
