[QGIS-Developer] GRIB files projection errors

[Saber Razmjooei]

Hi Paolo,

You can download the files directly from ECMWF. Maybe it is a bug with the
ZyGrib data processing.

For Crayfish you can compile it yourself:

Hi Saber,
thanks for checking. The sample mentioned in the ticket loads fine, but
its SRS is not recognized correctly (it appears as a custom EPSG,
whereas it should be 4326, I guess).
Further tests reveal that other gribs (downloaded with ZyGrib) have an
incorrect extent, and there fore are not loaded correctly. You can check
yourself or use this sample:

As for crayfish, I'd need a solution using plain QGIS, as I'd like to
build a plugin based on grib. Furthermore, I would not like to use
non-Debian binaries on my system.
All the best.
