[Qgis-user] Unable to open some LISTdata open data ESRI File Geodatabases

[Even Rouault]

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

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.
