The main distortions that hamper 3D reconstruction from 2D imagery are image dissimilarities, concealed areas, shadows, height discontinuities and discrepancies between smooth terrain and man-made features. A methodology is proposed to improve automatic photogrammetric extraction of an urban surface model from high resolution satellite imagery with the emphasis on strategies to reduce the effects of the cited distortions and to make image matching more robust. Instead of a “standard” stereoscopic approach, a digital surface model is derived from tri-stereoscopic satellite imagery. This is based on an extensive multi-image matching strategy that fully benefits from the geometric and radiometric information contained in the three images. The bundled triplet consists of an IKONOS along-track pair and an additional near-nadir IKONOS image. For the tri-stereoscopic study a densely built-up area, extending from the centre of Istanbul to the urban fringe, is selected. The accuracy of the model extracted from the IKONOS triplet, as well as the model extracted from only the along-track stereopair, are assessed by comparison with 3D check points and 3D building vector data.

From the different contributions made during this symposium it becomes clear that, after a set of new sensors like Envisat, Ikonos, Quickbird, ASTER, MODIS ... 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. Environmental protection, a new field of application was also the theme of several contributions. It must be started, nevertheless, that for the moment radar images remain the inherent tool for certain applications and Landsat TM and ETM+ for optical remote sensing, remain the "work horses". The recent difficulties with the Landcast sensor, however, may change this part of the "remote sensing landscape". But other sensors with others and sometimes more possibilities are ready to take over. Wo=ith new strategies for Earth observation being formulated, one may conclude that the remote sensing community really is in transition.
