TM Augmented 3D Location

Class Name: TM Augmented 3D Location

Superclass - <Location 3D>

Subclasses

This DRM class is concrete and has no subclasses.

Definition

An instance of this DRM class specifies a coordinate within the Augmented Transverse Mercator (ATM) 3D SRF.

See [ISO/IEC 18026] for a complete definition.

Secondary Pages in DRM Diagram:

This class appears on only one page of the DRM class diagram.

Example

  1. The British National Grid (BNG) uses Transverse Mercator. Note that the Transverse Mercator SRF is often used to describe areas that have greater north-south than east-west extent, and that distortion of scale, distance, direction and area increase away from the central meridian.
