usingNewLayer

Creates Layer Object with a key defined by the key parameter.

This layer object is a fluent object and can be used to chain method calls to the layer as per the example below.

NOTE: The layer created with usingNewLayer is a client-only layer. This means that it requires data to be added to it on the client. This is illustrated in the Feature Collection Filter Example.

Parameters

Example

var map = new Mapzania.Map("map-div", "AFRICA", function () {

  var geojson = {
    type: "FeatureCollection",
    features: [
      //... some feature data ...
    ]    
  };

    map.usingNewLayer("MY_LAYER")
      .addFeatureCollection(geojson)
      .filterByText("LandLocked=='Y'")
      .convertToCentroids()
      .style({ fillColor: "#0000FF"})
      .update();
});
