			In order to limit the WCS to a bounding box (e.g. from current region) a GDAL vrt file can be created from the WCS ASCII file using gdalbuildvrt:
			<source lang="bash">
			gdalbuildvrt wcs_geoserver_LL_BB.vrt wcs_geoserver_LL.wcs -te xmin ymin xmax ymax
			</source>

== Using WCS in GRASS GIS ==

One option is to register the WCS service via {{cmd|r.external|version=70}}.

First create ASCII file with this content, named e.g. "wcs_geoserver_LL.wcs":

<source lang="xml">
<WCS_GDAL>
<ServiceURL>http://demo.opengeo.org/geoserver/wcs?</ServiceURL>
<CoverageName>Img_Sample</CoverageName>
</WCS_GDAL>
</source>

or simply download this file from [http://svn.osgeo.org/gdal/trunk/autotest/gdrivers/data/geoserver.wcs here].

Start GRASS in a latlong location (EPSG 4326), then register the WCS file:

<source lang="bash">
r.external input=wcs_geoserver_LL.wcs output=wcs_data
</source>

Then you can look at the map in the wxGUI map display:

[[Image:WCS import with r external.png|thumb|center|400px|Import of WCS via r.external, display with RGB viewer]]
