ArcGIS Pro 3.4 API Reference Guide
ArcGIS.Core.Geometry Namespace / SpatialReference Class / GetPCSHorizon Method
A boolean indicating whether the horizon is inclusive or exclusive.
Version

GetPCSHorizon Method
Gets the horizon of the projected coordinate system.
Syntax
public Polygon GetPCSHorizon( 
   out bool isInclusive
)

Parameters

isInclusive
A boolean indicating whether the horizon is inclusive or exclusive.

Return Value

The horizon of the projected coordinate system.
Exceptions
ExceptionDescription
This instance is not a projected coordinate system.
Remarks
The horizon is the valid area of use based on the coordinates of the projected coordinate system. The horizon's coordinates will use the same linear unit of measure as the source projected coordinate system. The horizon can be inclusive or exclusive. Some projection horizons will include all but a small area. In those cases, it's easier to construct an exclusive horizon. The horizon can also be single or multipart polygon.
