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 surface coordinate for an SRF based on the Local Tangent Space Euclidean SRFT.

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 Space 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.
