Class GMLCodec<TFeature>

  const storePromise = WFSFeatureStore.createFromURL("http://sampleservices.luciad.com/wfs", "usrivers", {
    codec: new GMLCodec(),
    outputFormat: "text/xml; subtype=gml/3.1.1"
  });

A GMLCodec can also be used to decode a file directly from a url, using a UrlStore:

  //Create a Store with a GeoJson codec to decode the data
  const store = new UrlStore({
    target: url,
    codec: new GMLCodec()
  });

  //Use the store to create a model
  const model = new FeatureModel(store);

  //Create a layer for the model
  const layer = new FeatureLayer(model);

  //Add the layer to the map
  map.layerTree.addChild(layer);

Spatial reference

The reference for shape decoding process is determined in the following way and order:

• The reference passed to decode. Use it in case you want to override the reference for each decode request.
• The reference passed to the constructor. Allows you to set the reference yourself, overriding what is in the data. If you still want to override for a particular decode() operation, you can still do it, because the step 1 allows it.
• The reference specified in the data with the legacy crs field. This reference is used if you don't specify it in step 1 or 2.
• The specification default WGS:84 reference is used.
