MLNRasterDEMSource class

MLNRasterDEMSource is a map content source that supplies rasterized digital elevation model (DEM) tiles to be shown on the map. The location of and metadata about the tiles are defined either by an option dictionary or by an external file that conforms to the TileJSON specification. A raster DEM source is added to an MLNStyle object along with one or more MLNHillshadeStyleLayer objects. Use a hillshade style layer to control the appearance of content supplied by the raster DEM source.

Each raster-dem source defined by the style JSON file is represented at runtime by an MLNRasterDEMSource object that you can use to initialize new style layers. You can also add and remove sources dynamically using methods such as MLNStyle/addSource: and MLNStyle/sourceWithIdentifier:.

Currently, raster DEM sources only support the format used by Mapbox Terrain-RGB.

Example

let terrainRGBURL = URL(string: "maptiler://sources/terrain-rgb")!
let source = MLNRasterDEMSource(identifier: "hills", configurationURL: terrainRGBURL)
mapView.style?.addSource(source)
