I have a raster that I received from a colleague that has a different center northing parameter from another map in the same projection. All the rest of the region and projection information are correct. I think what I need to do is to re-project the new raster to match the center northing parameter of the old map. Which command should I be using to accomplish this within GRASS? Or, should I be using an external tool like gdalwarp on the original img file (before I import it into GRASS?
Thanks,
Kirk
Here is the output of r.region for the raster with the wrong center, and the output of v.region for a vector with the correct center:
