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.
Supported OGR Vector Formats
ESRI Shapefile
CSV
GML
KML
Mapinfo File
PostgreSQL/PostGIS
TIGER
For further available drivers go
here.
NOTES
To export areas with holes into, e.g., a Shapefile, while keeping the
holes as holes, the flag -c has to be used.
EXAMPLES
Export to Shapefile
Export lines from GRASS vector map to Shapefile 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 Shapefile format (generates /tmp/testogr.shp and related files):
v.out.ogr input=multi type=area dsn=/tmp olayer=testogr
Export 3D lines from GRASS vector map to Shapefile format:
v.out.ogr input=lines_3d type=line dsn=/tmp olayer=testogr lco="SHPT=ARCZ"
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
Export to KML (Google Earth)
Export faces (3D vectors) from GRASS vector map in KML format for Google Earth:
v.out.ogr in=buildings_3d dsn=buildings_3d.kml olayer=buildings_3d format=KML type=face
