Description

GetTileBasedDataArea returns a polygon that represents the union of the terrain's data tiles. It ignores the presense of any clip or erase features. This function provides a relatively fast means of extracting a rough approximation of the terrain's data area. 

pTrackCancel is a reference to a CancelTracker which can be used to escape the process. A NULL pointer ('Nothing' in VB) can be past if desired.
