<h2>DESCRIPTION</h2>

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


<h2>EXAMPLES</h2>

Import of GRASS user map:
<p><div class="code"><pre>
# run in LatLong location:
v.in.wfs url="http://mapserver.gdf-hannover.de/cgi-bin/grassuserwfs?" output=grass_users

v.db.select grass_users where="name ~ 'Markus'"
</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).
