I've built a simple ol3 map with wms-polygon overlay functionality from a local geoserver 2.8.0. I added a working "WMS GetFeatureInfo" from the ol3 examples.My problem is that I have some identical overlapping polygons with diffrent attributes. When I click on a polygon (with 10 identical copies) I just get the info from one feature (maybe the top one).
Instead of this I need a results from all of the identical overlapping features.
Does anybody know how to implement this, below is my attempt?
This is my code:
var wmsSource = new ol.source.TileWMS({ url: 'http:localhost:8082/geoserver/wms', params: {'LAYERS': 'gdi:M4_Porjektkarte'}, serverType: 'geoserver', }); var wmsLayer = new ol.layer.Tile({ source: wmsSource }); var view = new ol.View({ center: [0,0], zoom: 3 }); var map = new ol.Map({ layers: [wmsLayer], target: 'map', view: view }); map.on('singleclick', function(evt) { document.getElementById('info').innerHTML = ''; var viewResolution = /** @type {number} */ (view.getResolution()); var url = wmsSource.getGetFeatureInfoUrl( evt.coordinate, viewResolution, 'EPSG:3857', {'INFO_FORMAT': 'text/html'}); if (url) { document.getElementById('info').innerHTML = ''; } });
