From the different contributions made during this symposium it becomes clear that, after a set of new sensors like Envisat, Ikonos, Quickbird, ASTER, MODISÃ became operational, now also the applications have reached the operational stage. The development of adapted methodologies to this new generation of sensors needs a couple of years before entering the application stage. It is also clear that Very High Resolution data has entered definitively the remote sensing applications "forum", with the emphasis on studies dealing with resolutions adapted to new application areas, urban structures for example, something which was not possible in the past since the resolutions were not appropriate. Many contributions illustrate the use of sensors with a better and finer spectral resolution. With new strategies for Earth observation being formulated, one may conclude that the remote sensing community really is in transition.IOS Press is an international science, technical and medical publisher of high-quality books for academics, scientists, and professionals in all fields.
