Simple Click Identify With UTFGrid
This example shows how to add click identify capability to the parcel layer in your application using the UTFGrid data. When the map is clicked, an "click" event is triggered and the parcel at the mouse click location will be highlighted as a canvas layer.
var utfGrid = new Dmp.Layer.UtfGridCanvas(Dmp.Env.Connections["SS"].getBaseUrl() + 'GetUTFGrid.aspx?datasource=samplesite.dmp/parceltiles&z={
z }&x={x }&y={y }&obsId=window&obsSuccessMethod={cb }&obsErrorMethod={cb }&output=json',{ highlightMinZm: '17', highlightMaxZm:'18', clickHL:{ fillColor: 'rgba(255,0,255,0.3)', }fillTileSize: '4', map.addLayer(utfGrid); Run Sample Back To Index |
