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 8.5.6 Local tangent space Euclidean SRFT of 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. Consider a <Property Grid> instance that maps wind velocities along a coastline. The <Property Grid> instance uses an SRF derived from the Local Tangent Space Euclidean SRFT with the Y axis parallel to the coast.

  2. An SRF derived from the Local Tangent Plane Space Euclidean SRFT may be used to specify a topocentric coordinate system to model a building.

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.
