Apply terrain exaggeration

Vertically exaggerate terrain in a scene.

Use case

Vertical exaggeration can be used to emphasize subtle changes in a surface. This can be useful in creating visualizations of terrain where the horizontal extent of the surface is significantly greater than the amount of vertical change in the surface. A fractional vertical exaggeration can be used to flatten surfaces or features that have extreme vertical variation.

How to use the sample

Use the stepper to update terrain exaggeration.

How it works

1. Create an ArcGISTiledElevationSource and add it to a new Surface.
   • An elevation source defines the terrain based on a digital elevation model (DEM) or digital terrain model (DTM).
2. Add the surface to a Scene.
   • The surface visualizes the elevation source.
3. Set the surface’s elevation exaggeration using Surface.elevationExaggeration.
