[Qgis-user] File Geodatabase raster datasets readable in GDAL 3.7.0 (was Re: Unable to open some LISTdata open data ESRI File Geodatabases)

[Even Rouault]

Hi,

Just to inform you that GDAL 3.7.0 will include a driver to read 
directly File Geodatabase raster datasets: 
https://github.com/OSGeo/gdal/pull/7389 . I've successfully tested it 
against the below datasets, among others.

They will consequently be directly be usable by QGIS once QGIS is built 
against this GDAL version (whose release will be in May)
