Description

The input index is the terrain data source index of the embedded feature class. Valid values range from 0 to ITerrain.DataSourceCount-1.

The pAOI argument is the area of interest envelope that's used to indicate where to remove measurements.

pTrackCancel is a pointer to a CancelTracker object.

Notes

• Deleting data source data will create dirty tiles in the terrain. You will need to (re)build the terrain afterward. See ITerrainEdit.Build.
