EsriRest Layer Leaflet plugin

This plugin provides the ability to display and query ESRI REST services using the export feature and the identify feature. This treats the REST service as if it were a WMS service, as opposed to a normal tiled service.

The identify feature return a URL to a json file where a developer can use JSONP to extract information from an ArcGIS server.

L.TileLayer.EsriRest

• Description: Allows a developer to include an ESRI server in Leaflet using the ESRI REST API export function. It will also produce a URL based on a point that links to a JSON object returning information from the identify function.

Export Feature

• Usage: L.TileLayer.EsriRest(PATH_TO_SERVICE);

var wildfires = new L.TileLayer.EsriRest("http://wildfire.cr.usgs.gov/ArcGIS/rest/services/geomac_dyn/MapServer", {
    layers: '1,18',
    transparent: true
}).addTo(map);

Identify Feature

• Usage: tileLayer.getIdentifyUrl(<L.Point>, {ESRI REST Identify Parameters});

var wildfireUrl = wildfires.getIdentifyUrl(clickedPoint, {showLayers: 'all'});

• Note: The showLayers parameter was added to allow the developer to select they type of query. The layers parameter was also modified to only accept layer numbers. (ex. layers: 0,1,2) For more information on the ESRI REST identify feature NOAA has a great page about it.

Example
