1      Definition

A Data Type including the arrangement of the RADAR Objects and the RADAR Sub-Scenes in a scene.

2      Functional Requirements

A RADAR Scene Geometry instance must include:

  1. The RADAR Scene Geometry Header
  2. The ID of the RADAR Scene Geometry.
  3. The ID and the Space-Time information of the RADAR Objects in the RADAR Scene.
  4. The ID and the Space-Time information of the Sub-RADAR Scenes in the RADAR Scene.

A RADAR Scene Geometry instance may include:

  1. The ID of a Virtual Space (M-Instance) to which it refers.
  2. The ID of a U-Environment to which it refers.
  3. The Space-Time information of this RADAR Scene Geometry instance.
  4. Information about this RADAR Scene Geometry.
  5. Descriptive Metadata.

5     Conformance Testing

A Data instance Conforms with RADAR Scene Geometry (OSD-RSG) if:

  1. The Data validates against the RADAR Scene Geometry’s JSON Schema.
  2. All Data in the  RADAR Scene Geometry’s JSON Schema
    1. Have the specified type
    2. Validate against their JSON Schemas
    3. Conform with their Data Qualifiers.
