NAME

v.proj - Allows projection conversion of vector files.

SYNOPSIS

v.proj
v.proj help
v.proj [-sl] input=name location=name [dbase=name] [mapset=name] [out=name]

DESCRIPTION

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).

v.proj will create dig, dig_att, and dig_cats directories in the output mapset, if they do NOT exist. Map files for dig, dig_att, and dig_cats are also created for the new map layer.

Flags:

-s
Automatically run "v.support" on newly created vector file.
-l
List vector files in input location and exit

Parameters:

input=name
Name of the input vector map.
location=name
Name of the location containing input vector map
dbase=name
path to GRASS database of input location
mapset=name
Name of the mapset containing input vector map
output=name
Name of the output vector map.

If the user simply types v.proj without specifying parameter values on the command line, the program will prompt the user to enter these.

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.
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.
