The rule is that you can have only one projection in a location. If you have several projections you need several locations and to reproject data between them (r.proj, v.proj).GRASS can generate locations directly from metadata.
So far, I've failed to convince GRASS to do anything directly. Trying the auto route: grass64 -gui select define new location with georeferenced file select the dem file: k42.demselect the TN transformation, as probably better than the default for adjacent Kentucky
enter GRASS with the newly created location and the PERMANENT mapset
Results in this error:
"g.proj or projection error: ERROR: default region is invalid
line 3: <north: 1080:43:46N>"
So GRASS has automatically set up the location using degrees, and then
get confused when the raster co-ordinates are provided in meters. Which
appears to be fairly close to the sort of problem I ran into when
setting this up manually. What am I missing?
Thanks, Tyler
