<h2>DESCRIPTION</h2>

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

<h2>EXAMPLES</h2>

Import of world cities with population &gt; 1 million:
<p>
<div class="code"><pre>
# run in Latitude-Longitude location (EPGS code 4326):
# download geonam_gt1M layer:
v.in.wfs \
  url="http://mapserver.flightgear.org/ms?Service=WFS&amp;request=GetFeature&amp;version=1.0.0" \
  name=geonam_gt1M output=geonam_gt1M
</pre></div>

<p>
Download 25 ship wrecks from LINZ data service:
<br>
(first create yourself a free API key at
  <a href="http://data.linz.govt.nz/p/web-services/">http://data.linz.govt.nz/p/web-services/</a>)

<p>
<div class="code"><pre>
# run in LatLong location:
URL='http://wfs.data.linz.govt.nz/&lt;PUT YOUR API KEY HERE&gt;/wfs?'

# download available layers to wms_capabilities.xml
v.in.wfs -l url="$URL" 
</pre></div>

From that file we learn that the shipwreck layer is called "<tt>v:x633</tt>"
and that EPSG code 4326 (LatLong WGS84) is a supported SRS for this data layer.

<div class="code"><pre>
v.in.wfs url="$URL" output=linz_hydro_25_wrecks name="v:x633" srs="EPSG:4326" max=25
</pre></div>

<h2>REQUIREMENTS</h2>

The OGR library on the system needs to be compiled with Xerces C++ XML
Parser support (for GML).
