See https://grass.osgeo.org/grass78/manuals/r.in.gdal.html#notes "Georeferencing If the dataset has affine georeferencing information, this will be used to set the north, south, east and west edges. Rotational coefficients will be ignored, resulting in incorrect positioning for rotated datasets." https://grass.osgeo.org/grass78/manuals/r.in.gdal.html#error-messages "... the image must be first externally rotated, applying the rotation info stored in the metadata field of the raster image file. For example, the gdalwarp software can be used to transform the map to North-up (note, there are several gdalwarp parameters to select the resampling algorithm): gdalwarp rotated.tif northup.tif " Markus _______________________________________________ grass-user mailing list [email protected] https://lists.osgeo.org/mailman/listinfo/grass-user
