    Syntax
    Example
    Retrieve layers
    // find the first TIN layer
    var tinLayer = MapView.Active.Map.GetLayersAsFlattenedList().OfType<TinLayer>().FirstOrDefault();
    
    // find the first Terrain layer
    var terrainLayer = MapView.Active.Map.GetLayersAsFlattenedList().OfType<TerrainLayer>().FirstOrDefault();
    
    // find the first LAS dataset layer
    var lasDatasetLayer = MapView.Active.Map.GetLayersAsFlattenedList().OfType<LasDatasetLayer>().FirstOrDefault();
    
    // find the set of surface layers
    var surfacelayers = MapView.Active.Map.GetLayersAsFlattenedList().OfType<SurfaceLayer>();
    Create a LasDatasetLayer
    //Must be on the QueuedTask.Run()
    
    string lasPath = @"d:\Data\LASDataset.lasd";

    lasCP.IsVisible = false;
    
    //Create the layer to the LAS dataset
    var lasDatasetLayer = LayerFactory.Instance.CreateLayer<LasDatasetLayer>(lasCP, map);
    
    Create a LasDatasetLayer from a LasDataset
    //Must be on the QueuedTask.Run()
    
    var lasCP_ds = new LasDatasetLayerCreationParams(lasDataset);

    //Create the layer to the LAS dataset

    Create a LasDatasetLayer with renderers

    //Create the layer to the LAS dataset
    var lasDatasetLayer_rd = LayerFactory.Instance.CreateLayer<LasDatasetLayer>(lasCP_renderers, map);
    
    LAS Points Classification Unique Value Renderer
    // applies to LAS dataset layers only
    
    var lasPointsClassificationRendererDef = new LasUniqueValueRendererDefinition(LasAttributeType.Classification);
    // accept the defaults for color ramp, symbolTemplate, symbol scale factor
