SYNOPSIS
v.in.wfs
v.in.wfs --help
v.in.wfs [-lr] url=string output=name [name=string[,string,...]] [srs=string] [maximum_features=integer] [start_index=integer] [--overwrite] [--help] [--verbose] [--quiet] [--ui]

  Flags:

-l
    Download server capabilities to ’wms_capabilities.xml’ in the current directory and exit

-r
    Restrict fetch to features which touch the current region

--overwrite

--help
    Print usage summary

--verbose
    Verbose module output

--quiet
    Quiet module output

--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)

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).
