ras:Contour

GeoServer - User mailing list
Dear list
 
We want to implement ras:Contour WPS to our product.
So we are in struggle with owslib python library. The xml works perfectly, but we got problems to implement it into python code.
The problem is how we can put raster layer from geoserver to input parameters???
 
so the original xml is the next
 
<?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="http://www.opengis.net/wps/1.0.0" xmlns:wfs="http://www.opengis.net/wfs" xmlns:wps="http://www.opengis.net/wps/1.0.0" xmlns:ows="http://www.opengis.net/ows/1.1" xmlns:gml="http://www.opengis.net/gml" xmlns:ogc="http://www.opengis.net/ogc" xmlns:wcs="http://www.opengis.net/wcs/1.1.1" xmlns:xlink="http://www.w3.org/1999/xlink" xsi:schemaLocation="http://www.opengis.net/wps/1.0.0 http://schemas.opengis.net/wps/1.0.0/wpsAll.xsd">

the python code:
 
wps = WebProcessingService('http://localhost:8080/geoserver/wps', version='1.0.0', skip_caps=True, verbose=False)
wps.getcapabilities()
process_identifier='ras:Contour'
ComplexData()
input_data=dict(data=filepath)
input_tupled=[(k,v) for k,v in input_data.items()]
print(input_tupled)
exec_obj=wps.execute(process.identifier,input_tupled,output=[("result", False, 'application/json')])
monitorExecution(exec_obj)
for output in exec_obj.processOutputs:
print(output.identifier)
print(output.data)
