DESCRIPTION

52       v.proj allows a user to convert a vector map in a specified mapset of a
53       specified location (different from current) with  projection  of  input
54       location to the vector map in a current mapset of current location with
55       projection of current location (both projections are defined by  corre‐
56       sponding PROJ_INFO files).
57

NOTES

59       If out is not specified it is set to be the same as input map name.
60       If  dbase  is  not  specified it is assumed to be the current database.
61       The user only has to specify dbase if the source location is stored  in
62       another separate GRASS database.
63       If set is not specified, its name is assumed to be the same as the cur‐
64       rent mapset's name.
65
66       v.proj supports general datum transformations, making use of the PROJ.4
67       co-ordinate system translation library.
