Viewpoint Display
The Camera API provides viewpoint and closest lane information for each camera, when it is available and can be determined. These values help to indicate the direction(s) in which a camera may be facing. If available, it is recommended that the application should display the dynamically calculated view returned with the image, e.g., “The camera is currently facing West” (see GetCameraImage).
If the dynamic view is not available, it is recommended that the application should display the closest lane returned with the camera, e.g., “The traffic closest to the camera is travelling Eastbound” (see GetCamerasInBox).
If the closest lane is not available, it is recommended that the application should display the possible viewpoints, e.g., “This camera can face East/West” (see GetCamerasInBox).
Note: Drive streams contain heading information in the EXIF data for each image (see GET /vehicles/{vehicleId}/streams).
