My task is very straightforward: a user draws a polygon and queryqueries all parcel polygons. The query string extends the URL limit. So I am posting XML to WFS. However, GeoServer always returned 0 feature, but I knew the query polygon overlapped several tax parcels. If I passed a single point, it worked fine. Did I miss anything for sending a polygon? I used the OpenLayers buildGeometry to create the polygon GML. I can't figure out what's wrong.
Please Help. THANK YOU IN ADVANCE.
Here is my code:
var gml = new OpenLayers.Format.GML();
var polygonGML = gml.buildGeometry.polygon.apply(gml,[taArray[0].geometry])
console.log(polygonGML);
var plgGMLString = (new XMLSerializer()).serializeToString(polygonGML);
var geo_req_url = proxyHost + "http://localhost:8080/geoserver/wfs";
var query_xml = '<?xml version='
+ '<wfs:GetFeature service="WFS" version="1.1.0" xmlns:wfs="http://www.opengis.net/wfs" xmlns="http://www.opengis.net/ogc" xmlns:gml="http://www.opengis.net/gml" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.opengis.net/wfs http://schemas.opengis.net/wfs/1.1.0/wfs.xsd">'
+ '<wfs:Query typeName="topp:tax_parcel"><Filter><Intersects><PropertyName>geom</PropertyName>'
+ plgGMLString
+ '</Intersects></Filter></wfs:Query></wfs:GetFeature>';
$.post(
geo_req_url,
query_xml,
function(data) {
geoResults = data.features;
remove_selected_features();
draw_sel_features();
},
"application/json"
);
Here is the printout of plgGMLString.
<gml:Polygon> <gml:outerBoundaryIs> <gml:LinearRing> <gml:coordinates decimal="." cs="," ts=" ">-74.00567761405651,40.546826958183715 ...</gml:coordinates> </gml:LinearRing> </gml:outerBoundaryIs> </gml:Polygon>
