[GRASS-user] Reprojecting Vector Map

you cannot define a different spatial reference systems (SRS) for
mapsets in one location. Data in one location need to be in the same
SRS. This is fundamental feature of the GRASS database - "A LOCATION
is defined by its coordinate system, map projection and geographical
boundaries" [1].
