GeoReference clarification and real world relations

[heuerfin]

As discussed today we should harmonize and clarify some things regarding the georeferencing shape:

• Definition for BoundingBox. Should we fix the BoundingBox coordinates to a certain coordinates system? (e.g. EPSG:4326) This would make it easier to match e.g. the bounding box from a sensor trace to a map (without a transformation)
  • Should we introduce 2 BoundingBox'es: 1. for global harmonized system and 2. in the local map coordinate system
• Introduce a switch between "real world reference" and "no real world reference": to make it clear if it is synthetic or not

[MircoNierenz]

Do you need both bounding boxes at the same time or is an additional specification of the type of reference system enough - as mentioned as switch between ‘real world reference’ and ‘no real world reference’?
