If you are getting map data from a WMS service that supports GetFeatureInfo requests, you can request information about the properties of the features at a certain location.

To enable GetFeatureInfo requests, specify the queryLayers option when you construct your WMS model. Then, create a WMS layer that corresponds to your WMS model:

Once you added the WMS layer to a Map, you can call the getFeatureInfo method with view coordinates. The GetFeatureInfo request determines which feature is painted on the view at that location. The call returns a Promise to the requested feature information and its metadata.

The Data Formats sample and the ECDIS sample show the usage of the GetFeatureInfo request with WMS layers. More specifically, the GetFeatureInfoController class in the RIA toolbox uses the getFeatureInfo methods of the WMS layers to retrieve feature information at the mouse location, and shows that information on the map.
