esriSRPoleGeometry Constants

Describes the geometry of a pole in a projected coordinate system.

Constant Value Description
esriSRPole_​None 0 The pole for this projected coordinate system is outside the PCS horizon boundary.
esriSRPole_​IsPoint 1 The pole for this projected coordinate system is a point.
esriSRPole_​IsStraightLine 2 The pole for this projected coordinate system is a straight line.
esriSRPole_​IsCurvedLine 3 The pole for this projected coordinate system is a curved line.

Remarks

This enumeration is used for horizon objects that are based upon a projected coordinate system. Whether a pole is not present, a point, or a line matters when clipping and closing geometries after they are projected.
