NAME
v.proj - Allows projection conversion of vector files.
KEYWORDS
vector
SYNOPSIS
v.proj
v.proj help
v.proj [-lz] input=name location=string [mapset=string] [dbase=string] [output=name] [--overwrite]
Flags:
- -l
- List vector files in input location and exit (a dummy value must be given for input)
- -z
- (3-D vectors only) Assume z co-ordinate is ellipsoidal height and transform if possible
- --overwrite
- Force overwrite of output files
Parameters:
- input=name
- Name of input vector map
- location=string
- Location containing input vector map
- mapset=string
- Mapset containing input vector map
- dbase=string
- Path to GRASS database of input location
- output=name
- Name for output vector map
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
