Rule Name: LSR Model and Reference Surfaces

Definition

A Model defined using an LSR spatial reference frame (SRF) may not contain (aggregate) any Reference Surface instances.

Rationale

The intent of this rule is to limit the level of complexity for a transmittal consumer. If and when the SEDRIS API directly supports elevation resolution for Location 2D instances, this rule may be modified.

Example

FAQs

How is the elevation resolved for an LSR Location 2D instance in an LSR Model?

As explained in Reference Surface's FAQ list, when an LSR Location 2D is instanced, it is converted to a Location 2D in the scoping 3D SRF. Its elevation can then be determined in the 3D SRF.
