thermore, it is obvious that the mentioned three processing topics are influencing each other - for instance, the Object
extraction phase gives evidence about objects that have to be eliminated for the generation of an approximated DTM
which then can be re-computed, so that we will also implement an iterative and closed sequence of these topics Which
have been handled independently until now.
Finally it can be stated that the presented methods are significantly contributing to the initial goal of improving the
integration of elevation and image data, and thus also to the envisaged use and success of upcoming multi-sensor.
systems in the next few years.
