v.proj(1)

NAME
v.proj

DESCRIPTION
v.proj allows a user to convert a vector map in a specified mapset of a specified location (different from current) with projection of input location to the vector map in a current mapset of current location with projection of current location (both projections are defined by corresponding PROJ_INFO files).

NOTES
If out is not specified it is set to be the same as input map name.
If dbase is not specified it is assumed to be the current database. The user only has to specify dbase if the source location is stored in another separate GRASS database.
If set is not specified, its name is assumed to be the same as the current mapset's name.

v.proj supports general datum transformations, making use of the PROJ.4 co-ordinate system translation library.

EXAMPLES
v.proj in=mymap location=latlong mapset=user1
