Hello,
I am currently using the WPSextension for geoserver (2.10) and the python
script hooks in order to add my own processes. After adding this simple process:
from geoserver.wps import process
from geoscript.layer import GeoTIFF
@process(
inputs={'geom': (GeoTIFF, 'The geometry to buffer')},
outputs={'result': (str, 'The buffered geometry')},
title='Buffer',
description='Buffers a geometry'
)
def run(geom):
s = str(geom.getsize())
return s;
and the following wps execute request:
<?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";>
<ows:Identifier>Chadi:buffer</ows:Identifier>
<wps:DataInputs>
<wps:Input>
<ows:Identifier>geom</ows:Identifier>
<wps:Reference mimeType="image/tiff"
xlink:href="http://download.osgeo.org/geotiff/samples/misc/tjpeg.tif";
method="GET"/>
</wps:Input>
</wps:DataInputs>
<wps:ResponseForm>
<wps:RawDataOutput>
<ows:Identifier>result</ows:Identifier>
</wps:RawDataOutput>
</wps:ResponseForm>
</wps:Execute>
I noticed that geoserver download the image before giving a handle on the
"geom" object in the python script.
is it possible to disable this feature and to have only the URL reference
passed to the script hook ?
If no, is it possible to download locally the file before executing the script ?
Thanks in advance,
Chadi
