[Qgis-user] HDF Bug [Was: Raster formats in Qgis 3.4]

[Jorge Gustavo Rocha]

Hi Alex,

Thanks for the example. I was able to read it without any problem (in
current QGIS master version).

I'm still using GDAL 2.2.3.

You can see the dialog at
https://gist.github.com/jgrocha/347e8fee0828d3c3176ed1644d76f897

I didn't trace the fix, but the problem is already solved (I think).

Regards,

Jorge Gustavo
