WMS Layers

• ​http://dev.openlayers.org/releases/OpenLayers-2.9.1/doc/apidocs/files/OpenLayers/Layer/WMS-js.html

We could provide caching using TileCache - for both performance & the ability to work offline

• MapProxy also allows reprojection to different SRS

From a user perspective this just includes Remote WMS layers.

(Local WMS Layers would be seen as Shapefile Layers or Image Layers)

WMS GetFeatureInfo

• ​http://dev.openlayers.org/releases/OpenLayers-2.9.1/examples/getfeatureinfo-popup.html
• A single one for the server - not 1/layer!?

     info = new OpenLayers.Control.WMSGetFeatureInfo({
        url: 'http://demo.opengeo.org/geoserver/wms',
        title: 'Identify features by clicking',
        queryVisible: true,
        eventListeners: {
            getfeatureinfo: function(event) {
                map.addPopup(new OpenLayers.Popup.FramedCloud(
                    "chicken",
                    map.getLonLatFromPixel(event.xy),
                    null,
                    event.text,
                    null,
                    true
                ));
            }
        }
    });
    map.addControl(info);
    info.activate();
