Create terrain surface from a local raster

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

Use a terrain surface with elevation described by a raster file.


How it works

  1. Create a Scene and add it to a SceneView.
  2. Create a RasterElevationSource with a list of raster file paths.
  3. Add this source to the scene's base surface: Scene.BaseSurface.ElevationSources.Add(rasterElevationSource).

Additional information

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

Supported raster formats include:

  • CIB1, 5, 10
  • DTED0, 1, 2
  • GeoTIFF
  • HFA
  • HRE
  • IMG
  • JPEG
  • JPEG 2000
  • NITF
  • PNG
  • RPF
  • SRTM1, 2

The raster used in this sample is a DTED2 file.

Relevant API

  • RasterElevationSource
  • Surface
