Class Name: LSR Location 2D

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 Spatial Reference Frame (SRF).

See [I18026] for a complete definition.

Example

  1. <LSR Location 2D> instances are most commonly used in <Model> representations.

FAQs

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

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

Constraints
