NAME
v.proj - Re-projects a vector map from one location to the current location.
KEYWORDS
vector, projection, transformation
SYNOPSIS
v.proj
v.proj help
v.proj [-lz] [input=name] location=name [mapset=name] [dbase=path] [output=name] [--overwrite] [--verbose] [--quiet]
Flags:
- -l
- List vector maps in input location and exit
- -z
- Assume z co-ordinate is ellipsoidal height and transform if possible
- 3D vector maps only
- --overwrite
- Allow output files to overwrite existing files
- --verbose
- Verbose module output
- --quiet
- Quiet module output
Parameters:
- input=name
- Name of input vector map
- location=name
- Location containing input vector map
- mapset=name
- Mapset containing input vector map
- dbase=path
- Path to GRASS database of input location
- output=name
- Name for output vector map (default: input)
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 output is not specified it is set to be the same as input map
name.
If mapset is not specified, its name is assumed to be the same
as the current mapset's 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.
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
