LTSE Surface Location

Class Name: LTSE Surface Location

Superclass - <Location Surface>

Subclasses

This DRM class is concrete and has no subclasses.

Definition

An instance of this DRM class specifies a coordinate within the Local Tangent Space Euclidean (LTSE) Surface SRF.

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

Primary Page in DRM Diagram:

Secondary Pages in DRM Diagram:

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

Example

  1. A <Property Grid> instance maps wind velocities along a coastline. The <Property Grid> instance uses a Local Tangent Euclidean (Surface) SRF with the Y axis parallel to the coast.

FAQs

How does the Local Tangent Space Euclidean (LTSE) SRF differ from the Local Space Rectangular (LSR) SRF?

The Local Tangent Space Euclidean (Surface) SRF specifies a location in a georeferenced space. The Local Space Rectangular (2D) SRF specifies a location in a Cartesian, non-georeferenced "model" space.
