LSR 2D Location

Class Name: LSR 2D Location

Superclass - <Location 2D>

Subclasses

This DRM class is concrete and has no subclasses.

Definition

An instance of this DRM class specifies a coordinate within the Local Space Rectangular (LSR2) 2D 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. <LSR 2D Location> instances are most commonly used in <Model> representations.

FAQs

What if all the <Vertex> components of a <Polygon> instance use <LSR 2D Location> instances, and the <Polygon> instance crosses over two or more terrain facets?

By default, the <Polygon> instance should be draped across the terrain. This would cause the <Polygon> to be broken at the terrain facet boundaries, creating multiple polygons. If the Dont_Drape SE_Polygon_Flag is set on the <Polygon> instance, do not drape the <Polygon> instance. Instead, the <Vertex> components of the <Polygon> instance will conform to the terrain surface, while the interior of the <Polygon> instance may cut through the terrain.
