Hi there,
I have a raster map in Lat-Long projection and everything is fine with it.
However, I want to use r.los and since this module does not support
lat-long projection, I want to convert this map to utm.
So, I created a new location, in utm projection, in the corresponding zone
and then using the command r.proj I tried to reproject the map from the
lat-logng location to the utm. However, this process fails and I receive
the message:
GRASS_INFO_ERROR(2751,1): Input map is outside current region
I checked the regions in both location and they are exactly the same.
Then I tried to re-project a map from the Lat-Long location that is
significantly smaller from the utm region that I want to use, and it
failed again. So, I suspect that sthg else goes wrong.
Has anyone any idea how to overcome this problem or a link to a
step-by-step procedure on how to convert a lat-long map to utm?
Thanks a lot!
