Describes the type of horizon geometries generated by the Esri Projection Engine.
| Constant | Value | Description |
|---|---|---|
| esriSRHorizon_Envelope | 0 | The horizon for this projection is an envelope orthogonal to lat-long space. |
| esriSRHorizon_Polygon | 1 | The horizon for this projection is a polygon in lat-long space. |
| esriSRHorizon_Polyline | 2 | The horizon for this projection is all of geographic space with the exception of points along a polyline. |
| esriSRHorizon_Point | 3 | The horizon for this projection is all of geographic space with the exception of a single point. |
Remarks
Obsolete. Use the IProjectedCoordinateSystem4GEN::GetHorizon method which returns a geometry.
