DESCRIPTION

v.out.ogr converts GRASS vector data to OGR format. OGR (Simple Features Library) is part of the GDAL library, so you need to install gdal to use v.out.ogr.
To export areas with holes into, e.g., a SHAPE file, while keeping the holes as holes, the flag -c has to be used.

Supported OGR Vector Formats

ESRI Shapefile
Mapinfo File
TIGER
GML

EXAMPLES

Export to SHAPE

Export lines from GRASS vector map to SHAPE format (generates /tmp/testogr.shp and related files):

v.out.ogr input=multi type=line dsn=/tmp olayer=testogr

Export areas from GRASS vector map to SHAPE format (generates /tmp/testogr.shp and related files):

v.out.ogr input=multi type=area dsn=/tmp olayer=testogr

Export to GML

Export lines from GRASS vector map to GML format (generates /tmp/testogr.gml file with layer 'testogr'):

v.out.ogr input=multi type=line dsn=/tmp/testogr.gml olayer=testogr format=GML

Export to PostgreSQL/PostGIS

Export areas from GRASS vector map directly to PostGIS:

v.out.ogr input=polygons type=area \
          dsn="PG:host=localhost dbname=postgis user=postgres" \
          olayer=polymap format=PostgreSQL
