Hi Ian,
thanks for the hint. Had a look at the DescribeProcess response and the WPS
spec already but couldn't really get it working based on that.
The spec says:
Complex := InputId “=” Value *( “@” ComplexAttribute )
ComplexAttribute:= ComplexAttributeName “=” Value
ComplexAttributeName := “mimetype” | “encoding” | “schema"
Based on I assumed the syntax for the second parameter would be:
clip=<wkt-polygon-text>@mimetype=application/wkt.
But that didn't work unfortunately.
Cheers,
Max

You probably need to read the Spec
(http://portal.opengeospatial.org/files/?artifact_id=24151) - start around page
38 which covers how to specify and encode your parameters. As for which
parameters are needed look at the DescribeProcess response.

Hi,
I am having a bit of a hard time getting a WPS execution to run through a
GET request as the documentation about the geoserver specifics of this is a
bit sparse.
I want to use the gs:Clip function.
So, as a base I need the following parameters:
* service=wps
* version=1.0.0
* request=execute
* identifier=gs:Clip
Now I struggle with the Data inputs. The features to clip come directly from
a Geoserver layer whereas the clipping features are provided in WKT.
For the internal Geoserver feature I am using a standard WFS getFeature
request. Is there an internal pipeline for achieving the same:
*
features=@xlink:http://<my-geoserver-host>/geoserve/ows?service=WFS&version=1.0.0&request=GetFeature&typeName=<myLayer>&maxFeatures=50&outputFormat=application%2Fjson
For the WKT polygon I am a bit clueless. I tried:
* clip=<my-WKT-polygon>@mimeType=application/wkt
What am I missing here?
And what other parameters are required?
Thanks in advance
Max
