Hello to everyone! I've been working with some GeoServer processes using OpenLayers as client. I've been successful in those which use WFS as input (like gs:BufferFeatureCollection). My problem comes when I want to use processes that need as input raster data (tiff). I know that OpenLayers is not a WCS client, but you can send a POST request to the server to get back the result, right?. Particularly I want to execute the gs:RasterZontalStatistics, that needs a tiff and a WFS layer as input, and returns some statistics (average, min, max, etc.) for the tiff inside the geometries of the WFS Layer. This is the code I've used so far:
///*GEOPROCESS - Calculate the average/min/max values of the MDE raster according to user drawing selection*/ function obtainElevationProcess(){ var wpsFormat= new OpenLayers.Format.WPSExecute(); var doc= wpsFormat.write({ identifier: "gs:RasterZonalStatistics", dataInputs:[{ identifier:'data', reference:{ mimeType:"image/tiff", href: "http://geoserver/wcs", method: "POST", body: { wcs: { identifier:'forestry:mde200_V4', version:"1.1.1", domainSubset: { boundingBox: { projection: 'http://www.opengis.net/gml/srs/epsg.xml#3857', bounds: new OpenLayers.Bounds(-200931.8344047, 4681799.186142525,32948.35238090271, 4948113.428142309) } }, output: {format:'image/tiff'}, } } } }, { identifier:"zones", reference:{ mimeType:"text/xml; subtype=wfs-collection/1.0", href: "http://geoserver/wfs", method: 'POST', body:{ wfs:{ version:'1.0.0', outputFormat: "GML2", featureNS: "http://localhost:8080/thesis/forestry", featureType:'forestry:Lics', } } } }], responseForm:{ rawDataOutput:{ mimeType:"text/xml;subtype=wfs-collection/1.0", identifier:"statistics" } } }); OpenLayers.Request.POST({ url:"http://localhost:8080/geoserver/ows/", data:doc, headers: { "Content-Type": "text/xml;charset=utf-8" }, success: function(response){ alert(response.responseText); } }); }/ Once executed, OpenLayers returns this message (selection): /Process execution ecacba6c-a676-46b5-9010-bd4a2bb35632 failed Failed to retrieve value for input data Unrecognized request type {service=WCS, Output=image/tiff, Identifier=net.opengis.ows11.impl.CodeTypeImpl@1ad2fc (value: forestry:mde200_V4, codeSpace: null), DomainSubset=net.opengis.ows11.impl.BoundingBoxTypeImpl@111d0b5 (lowerCorner: [-200931.8344047, 4681799.1861425], upperCorner: [32948.352380903, 4948113.4281423], crs: http://www.opengis.net/gml/srs/epsg.xml#3857, dimensions: null), version=1.1.1}</ows:ExceptionText></ows:Exception></ows:ExceptionReport></wps:ProcessFailed></wps:Status></wps:ExecuteResponse>/ Does anyone an idea about how this can be done (if possible)?
