Create terrain surface from a tile package

This code sample is available for these platforms:
View Sample on GitHub

Set the terrain surface with elevation described by a local tile package.

screenshot

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 this source to the scene's base surface: Scene.BaseSurface.ElevationSources.Add(tiledElevationSource).

Relevant API

  • ArcGISTiledElevationSource
  • Surface

Additional information

The tile package must be a LERC (limited error raster compression) encoded TPK. Details on creating these are in the ArcGIS Pro documentation.

The terrain surface is what the basemap, operational layers, and graphics are draped on.
