Get tile-based terrain's Data Area.
[Visual Basic .NET] Public Function GetTileBasedDataArea ( _ ByVal pTrackCancel As ITrackCancel _ ) As IPolygon
[C#] public IPolygon GetTileBasedDataArea ( ITrackCancel pTrackCancel );
[C++]
HRESULT GetTileBasedDataArea(
ITrackCancel* pTrackCancel
);
[C++] Parameters pTrackCancel [in]
pTrackCancel is a parameter of type ITrackCancel*
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.
