Hi Andrea,
Thanks for the response. If the returning is feature is 4, will the WPS
return 1 extent for all the 4 returning features instead of 4 individual
extents?
One extent only. E.g., this is an example request against the local
tiger:roads layer:
<?xml version="1.0" encoding="UTF-8"?><wps:Execute version="1.0.0"
service="WPS" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="

<ows:Identifier>gs:Bounds</ows:Identifier>
<wps:DataInputs>
<wps:Input>
<ows:Identifier>features</ows:Identifier>
<wps:Reference mimeType="text/xml" xlink:href="http://geoserver/wfs"
method="POST">
<wps:Body>
<wfs:GetFeature service="WFS" version="1.0.0" outputFormat="GML2"
xmlns:tiger="http://www.census.gov">
<wfs:Query typeName="tiger:tiger_roads"/>
</wfs:GetFeature>
</wps:Body>
</wps:Reference>
</wps:Input>
</wps:DataInputs>
<wps:ResponseForm>
<wps:RawDataOutput>
<ows:Identifier>bounds</ows:Identifier>
</wps:RawDataOutput>
</wps:ResponseForm>
</wps:Execute>
If I save it into a file in /tmp/bounds.xml and post it to the GeoSolutions
demo GeoServer like this:
curl -H "Content-type: text/xml" -d @/tmp/bounds.xml "
http://demo.geo-solutions.it/geoserver/ows"
then the response is a single bounding box for the entire layer:
<?xml version="1.0" encoding="UTF-8"?><ows:BoundingBox xmlns:xs="
http://www.w3.org/2001/XMLSchema" xmlns:ows="http://www.opengis.net/ows/1.1"
crs="EPSG:4326"><ows:LowerCorner>-74.02722
40.684221</ows:LowerCorner><ows:UpperCorner>-73.907005
40.878178</ows:UpperCorner></ows:BoundingBox>
You can modify the WFS request embedded in the WPS one (acting as the data
source) in order to
filter the features being used to compute the bbox
Cheers
Andrea
