Carl, there have been a few successful efforts last year to prototype decyphering of rasters in .gdb, so it is now a matter of creating a proper GDAL driver from those findings. Sponsors could be welcome.
Looking at the dataset you point too, it seems that the grids are provided as XYZ in the ASCII directory You can get the contents of each .gdb with: ogrinfo -ro -al UKCS_Multi_Sat_Gravity_Data/ESRI/ESRI_Grids.gdb/a00000004.gdbtable ogrinfo -ro -al UKCS_Multi_Sat_Gravity_Data/GIS/GIS.gdb/a00000004.gdbtable Grids are the features with "Definition (String) = <DERasterDataset..."
