Hey all. I'm using a process which takes a line geometry, buffers it and creates a new feature. Then i intersect this new layer with a point layer using the gs:IntersectionFeatureCollection. Two problems appear:
1. When the geometries actually intersect (buffer is big enough) all is well but an exception gets thrown: > TRACE [geotools.util] - Error applying the converter class > org.geotools.util.GeometryConverterFactory$1 on (Tasmania,class > com.vividsolutions.jts.geom.MultiPoint) > com.vividsolutions.jts.io.ParseException: Unknown geometry type: Tasmania > (line 1) > at > com.vividsolutions.jts.io.WKTReader.parseErrorWithLine(WKTReader.java:427) > at > com.vividsolutions.jts.io.WKTReader.readGeometryTaggedText(WKTReader.java:495) 2. When the geometries do not intersect, i get the same exception but also an intersection feature (resulting gml) with empty geometry (the should be no intersection feature?): > > <gml:the_geom> > > <gml:MultiPoint srsName="http://www.opengis.net/gml/srs/epsg.xml#4326";> > > <gml:pointMember/> > > </gml:MultiPoint> > > </gml:the_geom> The WPS i'm executing is: > <?xml version="1.0" encoding="UTF-8"?> > <wps:Execute xmlns:wps="http://www.opengis.net/wps/1.0.0"; 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: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> > gs:IntersectionFeatureCollection > </ows:Identifier> > > <wps:DataInputs> > > <wps:Input> > > <ows:Identifier> > first feature collection > </ows:Identifier> > > <wps:Reference mimeType="text/xml; subtype=gml/3.1.1" > xlink:href="http://geoserver/wps"; method="POST"> > > <wps:Body> > > <wps:Execute version="1.0.0" service="WPS"> > > <ows:Identifier> > gs:Feature > </ows:Identifier> > > <wps:DataInputs> > > <wps:Input> > > <ows:Identifier> > crs > </ows:Identifier> > > <wps:Data> > > <wps:LiteralData> > EPSG:4326 > </wps:LiteralData> > > </wps:Data> > > </wps:Input> > > <wps:Input> > > <ows:Identifier> > typeName > </ows:Identifier> > > <wps:Data> > > <wps:LiteralData> > tasmania_roads_buffer_01 > </wps:LiteralData> > > </wps:Data> > > </wps:Input> > > <wps:Input> > > <ows:Identifier> > geometry > </ows:Identifier> > > <wps:Reference mimeType="text/xml; subtype=gml/3.1.1" > xlink:href="http://geoserver/wps"; method="POST"> > > <wps:Body> > > <wps:Execute version="1.0.0" service="WPS"> > > <ows:Identifier> > JTS:buffer > </ows:Identifier> > > <wps:DataInputs> > > <wps:Input> > > <ows:Identifier> > distance > </ows:Identifier> > > <wps:Data> > > <wps:LiteralData> > 0.01 > </wps:LiteralData> > > </wps:Data> > > </wps:Input> > > <wps:Input> > > <ows:Identifier> > geom > </ows:Identifier> > > <wps:Reference mimeType="text/xml; subtype=gml/3.1.1" > xlink:href="http://geoserver/wps"; method="POST"> > > <wps:Body> > > <wps:Execute version="1.0.0" service="WPS"> > > <ows:Identifier> > gs:CollectGeometries > </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 xmlns:gurs="http://www.gurs.com"; service="WFS" > version="1.0.0" outputFormat="GML2"> > > > <wfs:Query typeName="topp:tasmania_roads"/> > > > </wfs:GetFeature> > > </wps:Body> > > </wps:Reference> > > </wps:Input> > > </wps:DataInputs> > > <wps:ResponseForm> > > <wps:RawDataOutput mimeType="text/xml; subtype=gml/2.1.2"> > > <ows:Identifier> > result > </ows:Identifier> > > </wps:RawDataOutput> > > </wps:ResponseForm> > > </wps:Execute> > > </wps:Body> > > </wps:Reference> > > </wps:Input> > > </wps:DataInputs> > > <wps:ResponseForm> > > <wps:RawDataOutput mimeType="text/xml; subtype=gml/2.1.2"> > > <ows:Identifier> > result > </ows:Identifier> > > </wps:RawDataOutput> > > </wps:ResponseForm> > > </wps:Execute> > > </wps:Body> > > </wps:Reference> > > </wps:Input> > > </wps:DataInputs> > > <wps:ResponseForm> > > <wps:RawDataOutput mimeType="text/xml; subtype=wfs-collection/1.0"> > > <ows:Identifier> > result > </ows:Identifier> > > </wps:RawDataOutput> > > </wps:ResponseForm> > > </wps:Execute> > > </wps:Body> > > </wps:Reference> > > </wps:Input> > > <wps:Input> > > <ows:Identifier> > second feature collection > </ows:Identifier> > > <wps:Reference mimeType="text/xml" xlink:href="http://geoserver/wfs"; > method="POST"> > > <wps:Body> > > <wfs:GetFeature xmlns:gurs="http://www.gurs.com"; service="WFS" > version="1.0.0" outputFormat="GML2"> > > <wfs:Query typeName="topp:tasmania_cities"/> > > </wfs:GetFeature> > > </wps:Body> > > </wps:Reference> > > </wps:Input> > > <wps:Input> > > <ows:Identifier> > intersectionMode > </ows:Identifier> > > <wps:Data> > > <wps:LiteralData> > INTERSECTION > </wps:LiteralData> > > </wps:Data> > > </wps:Input> > > </wps:DataInputs> > > <wps:ResponseForm> > > <wps:RawDataOutput mimeType="text/xml; subtype=wfs-collection/1.0"> > > <ows:Identifier> > result > </ows:Identifier> > > </wps:RawDataOutput> > > </wps:ResponseForm> > </wps:Execute> Geoserver is 2.5.2. So is this a feature or a bug? One potential problem i see is that in IntersectionFeatureCollection.java there is only a simple check: > if (((Geometry) attribute).getNumGeometries() > 0) { but no check like: > ((Geometry) attribute).isEmpty() -- View this message in context: http://osgeo-org.1560.x6.nabble.com/WPS-problem-2-5-2-tp5167597.html Sent from the GeoServer - User mailing list archive at Nabble.com. ------------------------------------------------------------------------------ Comprehensive Server Monitoring with Site24x7.
