[GRASS-user] error when importing soil grids data into GRASS

[Laura Poggio]

Hi Veronica,
thanks for pointing this out. The projection should be defined in the VRTs
of Soilgrids 2.0 and normally it should be recognised in GRASS-GIS. I have
been using the same files you mentioned. We will look into the issue and
let you know.

Thanks
Laura
