--ui
    Force launching GUI dialog

  Parameters:

url=string [required]
    Base URL starting with ’http’ and ending in ’?’

output=name [required]
    Name for output vector map

name=string[,string,...]
    Comma separated names of data layers to download

srs=string
    Specify alternate spatial reference system (example: EPSG:4326)
    The given code must be supported by the server, consult the capabilities file

maximum_features=integer
    Maximum number of features to download
    (default: unlimited)

start_index=integer
    Skip earlier feature IDs and start downloading at this one
    (default: start with the first feature)

username=string
    Username or file with username or environment variable name with username

password=string

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 location (EPGS code 4326):
# download "sentinel:mgrs" layer:
v.in.wfs url="https://geoserver.mundialis.de/geoserver/sentinel/wfs?" name="sentinel:mgrs" output=sentinel2_mgrs

  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 location:
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).
