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)

Hi Peter,
yes I confirm this dataset is a raster gdb. I can sort-of open it with
my QGIS + GDAL master build using the OpenFileGDB driver, but you'll see
the raster tables in a raw unusable way. For example layers like
fras_blk_NCH_ES_WATER_LOGGING_HAZARD which contains the tiles as
compressed data in a BLOB column.
You could try the https://github.com/r-barnes/ArcRasterRescue utility to
convert into GeoTIFF
FWIW, I've had more luck with the fork at
https://github.com/justinfisk/ArcRasterRescue

You could also kindly or not kindly suggest your administration to not
use proprietary formats for open data whereas thereare so many open
alternatives, like GeoTIFF...
Small "advertizing": for those interesting, there's a funding
opportunity to develop a GDAL open source raster driver to be able to
read filegdb rasters that QGIS could use to open directly such files.
Contact me off-list if interested.

Hello
I've downloaded some datasets from the LISTdata open data repository
(https://listdata.thelist.tas.gov.au/opendata/index.html) - which is a great
service.
However, I can't open any datasets that are solely an ESRI File Geodatabase,
e.g.
https://listdata.thelist.tas.gov.au/opendata/data/NCH_ES_WATER_LOGGING_HAZARD_STATEWIDE.zip
(279 MB)
Maybe these are raster gdb datasets? How can I tell if that is the case?
Is there any way the open a raster gdb other than with ESRI software?
I can open gdb files in QGIS from LISTdata that are included as part of a set with
shapefile and MapInfo tab files (e.g. in the "Tasmanian Irrigation Irrigation
District" dataset). I'm guessing that is because these are vector gdb files?
I'm running QGIS 3.10.6 ltr on Windows 10 64-bit (yes I know it's not the latest ltr, but
it was the most recent "portable" build I have been able to find and run
successfully).
Thanks
