DESCRIPTION
v.in.wfs imports OGC WFS maps (Web Feature Service) from external servers.
EXAMPLES
Import of world cities with population > 1 million:
# run in Latitude-Longitude location (EPGS code 4326):
# download geonam_gt1M layer:
v.in.wfs \
url="http://mapserver.flightgear.org/ms?Service=WFS&request=GetFeature&version=1.0.0" \
name=geonam_gt1M output=geonam_gt1M
Download 25 ship wrecks from LINZ data service:
(first create yourself a free API key at http://data.linz.govt.nz/p/web-services/)
# run in LatLong location:
URL=’http://wfs.data.linz.govt.nz/<PUT YOUR API KEY HERE>/wfs?’
# download available layers to wms_capabilities.xml
v.in.wfs -l url="$URL"
From that file we learn that the shipwreck layer is called "v:x633" and that EPSG code
4326 (LatLong WGS84) is a supported SRS for this data layer.
v.in.wfs url="$URL" output=linz_hydro_25_wrecks name="v:x633" srs="EPSG:4326" max=25
REQUIREMENTS
The OGR library on the system needs to be compiled with Xerces C++ XML Parser support (for
GML).
