Vector add-ons

See also

svn co builds PostGIS topology for feature tables linked via v.external.


v.colors is much like r.colors, but may be used for vector maps.


v.external.all creates (using v.external) in the current mapset new pseudo-vector maps for all OGR layers from given OGR datasource (dsn option). imports all elements saved into Geopaparazzi.

  • is a C program that imports a PLY file and writes it as GRASS vector map.
Author: Markus Metz imports DWG files into GRASS., see also here
Author: Rodrigo Rodrigues da Silva imports OGC WFS maps (Web Feature Service) from external servers.


v.median create the median point of a cloud of point. estimates the optimal route to visit nodes on a vector network and optionally tries to improve the result.


  • v.out.ply is a C program that exports a GRASS vector map as PLY file.
Author: Markus Metz


v.ply.rectify imports a PLY point cloud, georeferences and exports it. The first three vertex properties must be the x, y, z coordinates with property names "x", "y", "z", in this order.

Inverse cost weighting is like inverse distance weighted (IDW) interpolation, but uses cost instead of shortest Euclidean distance. In this way solid barriers and molasses zones may be correctly taken into account.
