## DESCRIPTION

v.in.wfs imports OGC WFS maps (Web Feature Service) from external servers.

## EXAMPLES

### WFS import without credentials

Import of Copernicus Sentinel-2 satellite scene footprints:

    # run in Latitude-Longitude project (EPGS code 4326):
    # download "sentinel:mgrs" layer:
    v.in.wfs url="https://geoserver.mundialis.de/geoserver/sentinel/wfs?" name="sentinel:mgrs" output=sentinel2_mgrs
    # download NRW ALKIS "ave:Flurstueck" attribute:
    # set the AOI beforehand with g.region and limit import to current region with -r flag
    v.in.wfs url="https://www.wfs.nrw.de/geobasis/wfs_nw_alkis_vereinfacht?" -r output=wfs_alkis_vereinfacht srs=25832
    name="ave:Flurstueck" version="2.0.0" layer="Flurstueck"

### WFS import with API key

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 project:
    URL='http://wfs.data.linz.govt.nz/<PUT YOUR API KEY HERE>/wfs?'

    # download list of 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).
