The Basic Offline Map Scene Description (OSD-BOS) AIM describes the acquired Basic Offline Map Object as Basic Offline Map Scene Descriptors. Spatial Attitude is an optional input, so that the same AIM serves applications that have an ego Spatial Attitude to connect to it and applications that do not.

| Spatial Attitude | Spatial Attitude of the application (ego), when it has one. | |
| Produces | Basic Offline Map Scene Descriptors | The description of the Offline Map scene. |
