Superclass - <Location 3D>

Subclasses

Definition

An instance of this DRM class specifies a 3D coordinate for an SRF based on the Celestiodetic SRFT.

See 8.5.4 Celestiodetic SRFT of ISO/IEC 18026 for a complete definition.

Example

1. Consider a transmittal representing Walt Disney World in Orlando, Florida. The <Transmittal Root> instance has an <Environment Root> component ER with srf_context_info specifying that a designated spatial surface is part of the SRF context info and is SRM_DSSCOD_WGS84_ELLIPSOID, an SRF derived from the Celestiodetic SRFT is being used with ORM SRM_ORMCOD_WGS_1984, reference transformation SRM_RTCOD_WGS_1984_IDENTITY, and specifying angular unit EUC_DEGREE_ARC and linear unit EUC_METRE. A <Feature Node> instance within the component tree of ER represents Cinderella Castle and has a <CD 3D Location> instance with a coordinate value of longitude = -81.35, latitude = 28.25, and ellipsoidal_height = 15.0.
