Description

Used to delete points from a terrain dataset.

index is used to indicate which data source to delete points from. The data source must be a multipoint or point based feature class. It can be embedded or referenced.

pAOI is an envelope or polygon used to define an area of interest. Points inside pAOI will be deleted.

pTrackCancel is a reference to a CancelTracker to support progress reporting and the ability to halt the process. To bypass this feature pass a NULL pointer.

Notes:

The terrain will need to be rebuilt after calling this method.

A call should be made to ITerrainEdit2.UpdateExtent if extent in XY or Z has shrunk.
