Q: How to change map/image projections, datums, etc in GRASS GIS?
A:
- create an import location in the projection and datum of the map/image you want to import
- import the map/image into the location
- create a destination location in the projection and datum you want to reproject the map/image into
- working in the destination location, use r.proj or v.proj (depending on whether the map/image is raster or vector) to reproject the map/image from the import location to the destination location.
