EC Surface Location

Class Name: EC 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 Equidistant Cylindrical SRFT.

See ISO/IEC 18026 for a complete definition.

Example

  1. Consider a transmittal that contains an <Environment Root> instance R, the ORM of which is SRM_ORM_MULTIGEN_FLAT_EARTH_1989, so that the srf_info field of R is specified in the Equidistant Cylindrical SRF. An <EC Surface Location> instance within this SRF might have coordinate field values of easting = 30.0, northing = 50.0.
