26   Parameters:
27       input=name
28           Name of input vector map
29
30       location=string
31           Location containing input vector map
32
33       mapset=string
34           Mapset containing input vector map
35
36       dbase=string
37           Path to GRASS database of input location
38
39       output=name
40           Name for output vector map
41

DESCRIPTION

43       v.proj allows a user to convert a vector map in a specified mapset of a
44       specified  location  (different  from current) with projection of input
45       location to the vector map in a current mapset of current location with
46       projection  of current location (both projections are defined by corre‐
47       sponding PROJ_INFO files).
48

NOTES

50       If out is not specified it is set to be the same as input map name.
51       If dbase is not specified it is assumed to  be  the  current  database.
52       The  user only has to specify dbase if the source location is stored in
53       another separate GRASS database.
54       If set is not specified, its name is assumed to be the same as the cur‐
55       rent mapset's name.
56
57       v.proj supports general datum transformations, making use of the PROJ.4
58       co-ordinate system translation library.
