Name: RemoveTerrainPyramidLevel Example
Description: This script demonstrates how to add new
points to a terrain with the DeleteTerrainPoints tool, then use
the ChangeTerrainReferenceScale and RemoveTerrainPyramidLevel to
to adjust the pyramids for reducing the amount of data stored for
providing an optimized display performance.
