ITinAdvanced.GetDataArea Method

Returns a polygon representing the data area of the TIN.

[Visual Basic .NET]
Public Function GetDataArea ( _
) As IPolygon
[C#]
public IPolygon GetDataArea (
);
[C++]
HRESULT GetDataArea(
void
);

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Description

Returns the data area of the TIN as a ZAware polygon. The data area is defined as the boundary between those triangles that are marked as 'inside' and those marked as 'outside'. It is the same thing as the interpolation zone.

The returned polygon is topologically simplified. This is done to ensure everything about the polygon is valid. A consequence is that some vertices may have been moved (snapped) slightly and therefore do not exactly match the corresponding TIN node positions. If you require an exact match consider using ITinPolygon.AsPolygon.
