Set the terrain surface with elevation described by a local tile package.
      
  
    
Use case
In a scene view, the terrain surface is what the basemap, operational layers, and graphics are draped onto. For example, when viewing a scene in a mountainous region, applying a terrain surface to the scene will help in recognizing the slopes, valleys, and elevated areas.
How to use the sample
When loaded, the sample will show a scene with a terrain surface applied. Pan and zoom to explore the scene and observe how the terrain surface allows visualizing elevation differences.
How it works
- Create an 
ArcGISSceneand add it to aSceneView. - Create an 
ArcGISTiledElevationSourcewith the path to the local tile package. - Add this source to the scene's base surface: 
ArcGISScene.getBaseSurface().getElevationSources().add(ArcGISTiledElevationSource). 
Relevant API
- ArcGISTiledElevationSource
 - Surface
 
About the data
This sample uses the Monterey Elevation tile package, using CompactV2 storage format (.tpkx).
Additional information
The tile package must be a LERC (limited error raster compression) encoded TPK/TPKX. Details can be found in the topic Share a tile package in the ArcGIS Pro documentation.
