GetDataArea Method—ArcGIS Pro

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

C#
Visual Basic (Declaration)

public Polygon GetDataArea()

Public Function GetDataArea() As Polygon

Return Value

A ArcGIS.Core.Geometry.Polygon.

Exceptions

Exception	Description
ArcGIS.Core.Data.Exceptions.GeodatabaseException	A geodatabase-related exception has occurred.
ArcGIS.Core.CalledOnWrongThreadException	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();

Requirements

Target Platforms: Windows 11, Windows 10
