DESCRIPTION

60       v.out.ogr converts GRASS vector data to OGR format.  OGR  (Simple  Fea‐
61       tures Library) is part of the GDAL library, so you need to install gdal
62       to use v.out.ogr.
63       To export areas with holes into, e.g., a SHAPE file, while keeping  the
64       holes as holes, the flag -c has to be used.
65
66   Supported OGR Vector Formats
67       ESRI Shapefile
68       CSV
69       GML
70       KML
71       Mapinfo File
72       PostgreSQL/PostGIS
73       TIGER

EXAMPLES

78   Export to SHAPE
79       Export   lines  from  GRASS  vector  map  to  SHAPE  format  (generates
80       /tmp/testogr.shp and related files):
81
82       v.out.ogr input=multi type=line dsn=/tmp olayer=testogr
83        Export  areas  from  GRASS  vector  map  to  SHAPE  format  (generates
84       /tmp/testogr.shp and related files):
85
86       v.out.ogr input=multi type=area dsn=/tmp olayer=testogr
87
88
89   Export to GML
90       Export   lines   from   GRASS  vector  map  to  GML  format  (generates
91       /tmp/testogr.gml file with layer 'testogr'):
92
93       v.out.ogr  input=multi  type=line  dsn=/tmp/testogr.gml  olayer=testogr
94       format=GML
95
96
97   Export to PostgreSQL/PostGIS
98       Export areas from GRASS vector map directly to PostGIS:
99
100       v.out.ogr input=polygons type=area \
101                 dsn="PG:host=localhost dbname=postgis user=postgres" \
102                 olayer=polymap format=PostgreSQL
103
104
105   Export to KML (Google Earth)
106       Export  faces  (3D  vectors)  from  GRASS  vector map in KML format for
107       Google Earth:
108       v.out.ogr in=buildings_3d dsn=buildings_3d.kml olayer=buildings_3d for‐
109       mat=KML type=face
