Here 2.5 wild guesses: If it is about "pushing around" a raster map (no squeezing): - https://grass.osgeo.org/grass78/manuals/r.region.html If a rotation is needed: - https://grass.osgeo.org/grass7/manuals/addons/i.rotate.html If it is about a real transform: - convert the raster matrix to its vector center point representation; then - https://grass.osgeo.org/grass78/manuals/v.transform.html - rasterize again But again, just some almost random ideas. best, Markus _______________________________________________ grass-user mailing list grass-user@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/grass-user
