The current way of communicating situation awareness through sketches has been found not sufficient as is seen during exercises of usar.nl. The proposed solution RubbleViewer presents the personnel with a 3d map where they can annotate information on. This map of a collapsed building is calculated by running photogrammetric algorithms on an image dataset captured by a sUAV flown over a real disaster area. RubbleViewer is found useful during an evaluation with usar.nl personnel.
