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

EXAMPLE

Export lines from GRASS vector map to SHAPE format (generates /tmp/testogr.shp and related files):
v.out.ogr input=multi typ=line dsn=/tmp layer=testogr

Export areas from GRASS vector map to SHAPE format (generates /tmp/testogr.shp and related files):
v.out.ogr input=multi typ=area dsn=/tmp layer=testogr

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 layer=testogr format=GML

Export areas from GRASS vector map directly to PostGIS:
v.out.ogr input=polygons type=area dsn="PG:host=localhost dbname=postgis user=postgres" layer=polymap format=PostgreSQL
