v.proj: Re-projects a vector map from one location to the current location.


v.proj - Re-projects a vector map from one location to the current location.


vector, projection, transformation
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)
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).


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.
