The choice of the sensor modeling should be based on the desired accuracy, available control, and accessibility to the system’s internal and external characteristics. With the increased need for more automation in the mapping process, higher order primitives that could be automatically extracted from the imagery should be incorporated in the photogrammetric bundle adjustment. In this regard, having flexible models that can deal with various imaging modalities and primitives that can be easily included in existing bundle adjustment procedures would be quite advantageous.
