The OpenFileGDB driver provides read access to rster layers of File Geodatabases (.gdb directories) created by ArcGIS 10 and above. The dataset name must be the directory/folder name, and it must end with the .gdb extension. It can also read directly zipped .gdb directories (with .gdb.zip extension), provided they contain a .gdb directory at their first level. The driver supports: - reading CRS information - reading geotransform - exposing overviews - exposing nodata mask band or nodata value - uncompressed, LZ77, JPEG and JPEG2000 compression methods. - exposing value attribute tables as GDAL Raster attribute tables.

@rouault, thanks for implementing that. Could you point me to an example where raster data is accessed via gdal? I am quite new to gdal....I have installed gdal 3.7.1 and also have a .gdb file but cannot seem to get the raster layers. I can, however, list them using the fiona package. Thanks for your help! |
