Class TileLayerView

Draw 2D Map files for online maps. Supports WMS and WMTS tile formats.

Constructors

constructor

new TileLayerView(
viewContext: TileLayerViewContext,
rasterSource: WmsRasterSource | WmtsRasterSource,
): TileLayerView
TileLayerView can show tiled map data. WMS or WMTS supported for now. Not a full terrain engine.
Parameters
- viewContext: TileLayerViewContext
  See example for
- rasterSource: WmsRasterSource | WmtsRasterSource
  Either WmsRasterSource or WmtsRasterSource
Returns TileLayerView
Example
```
const viewContext: TileLayerViewContext = {
     cogsControl: control,
     camera: control.runtime.Camera.get("Camera"),
     cameraController : viewer.cameraController,
     mode2d: false
  }
```
