Add elevation source from tile package

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

1. Create a Scene and add it to a SceneView.
2. Create an ArcGISTiledElevationSource with the path to the local tile package.
3. Add the source to the scene’s base surface.

Offline data

This sample uses the Monterey Elevation tile package, using CompactV2 storage format (.tpkx). It is downloaded from ArcGIS Online automatically.

Additional information

The tile package must be a LERC (limited error raster compression) encoded TPK/TPKX. Details on the topic can be found in Share a tile package in the ArcGIS Pro documentation.
