DIGITAL PHOTOGRAMMETRIC SYSTEMS AND THEIR INTEGRATION WITH GIS IAN DOWMAN University College London Gower Street London WCIE 6BT United Kingdom ABSTRACT Digital photogrammetric systems have been a subject of research and development for a number of years but there is now commercially available equipment and software which has been developed and is supported by major manufacturers. The production of software for extraction of digital elevation models and their use for generating geocoded images is of particular importance. One of the forces behind such development has been the increased need for spatial data for geographical information systems and the use of data from earth observation satellites for this purpose; as a result of this, software packages available for image processing and GIS often include routines for orientation and correction of aerial and satellite images. The result of these developments is increased integration between remote sensing, photogrammetry and GIS. This paper reviews recent developments in digital photogrammetric systems with emphasis on those which are integrated with GIS. The functionality of the systems will be analysed and evaluated with particular attention paid to the requirements of topographic mapping and GIS. It is important that the user is able to evaluate the quality of the products derived from the digital processing and to monitor each step of the procedure. Current research will also be reviewed and an assessment made on the progress of development of feature extraction algorithms and the prospects for widespread use of such routines.
