PS Surface Location

Class Name: PS Surface Location

Superclass - <Location Surface>

Subclasses

This DRM class is concrete and has no subclasses.

Definition

An instance of this DRM class specifies a surface coordinate for an SRF based on the Polar Stereographic SRFT.

See 8.5.23 Polar stereographic SRFT of ISO/IEC 18026 for a complete definition.
