ITGIS_Shape.Area method
DK for ActiveX | TatukGIS_XDK11.ITGIS_Shape.Area | Methods | Properties
Calculates the planar area enclosed by the shape.
Syntax
// C# public double Area();
' VisualBasic Public Function Area() As Double
// Oxygene public function Area : Double;
Result
| Type | Description |
|---|---|
| double Double | Area in square map units. Returns zero for non-polygon shapes. |
Remarks
PURPOSE: Calculate planar area for polygon geometry in vector analysis, thematic filtering, and spatial statistics.
BEHAVIOR: For polygon shapes, computes the area enclosed by the exterior ring and applies interior ring subtraction for holes. For point and line shapes, returns zero.
CONSTRAINTS: This is a planar calculation in layer map units and does not account for geodetic distortion. Use AreaCS for geodetic area in square meters.
