Class Name: LSR Location 2D

Superclass - Location 2D

Definition

A coordinate within the Local Space Rectangular (LSR2) 2D Spatial Reference Frame (SRF).

Defines a right-handed 2D coordinate system where the X and Y axes are measured in meters (excepting in the case of a unitless/dimensionless model). The origin is arbitrary, and the semantic direction of "forward" is specified parametrically for use in coordinate operations with respect to other Spatial Reference Frames (e.g., instancing a model into a geodetic SRF).

See the SEDRIS Spatial Reference Model (SRM) for additional details.

FAQs

What if all of the Vertices 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_DONT_DRAPE_POLYGON polygon flag is set on the Polygon, then do not drape the Polygon. Instead, the Vertices of the Polygon will conform to the terrain surface, while the interior of the Polygon may cut through the terrain.
