Example

In This Topic
    GetDataArea Method
    In This Topic
    Gets the data area of the TIN as a Z-aware polygon. This method must be called on the MCT. Use QueuedTask.Run.
    Syntax
    public Polygon GetDataArea()
    Public Function GetDataArea() As Polygon

    Return Value

    Exceptions
    ExceptionDescription
    A geodatabase-related exception has occurred.
    This method or property must be called within the lambda passed to QueuedTask.Run
    Remarks
    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.
    Example
    Get Data Area
    var dataArea = tinDataset.GetDataArea();
