Describes the type of horizon geometries generated by the Esri Projection Engine.
|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.|
Obsolete. Use the IProjectedCoordinateSystem4GEN::GetHorizon method which returns a geometry.
