It Yers at the t Stuttgart e original research in at other rehensive under way and will be presented at the Ottawa Symposium. The most important activities are reported below. Integration of GPS, INS, Laser Scanners and Digital Cameras for Aerial Mapping: GPS is used for automatic positioning and orientation of the sensor platform. With an operational, automatic ambiguity solution available, real-time kinematic GPS can be used for sensor platform positioning. Developments are under way to fully integrate inertial systems with GPS for on-line altitude determination, however, the high price of inertial units is still an obstacle. Digital or video images are collected together with the positional information. Aerial video is becoming a popular tool for taking inventory of forests and wildlife management. As high resolution digital cameras (» 2,000 x 2,000 pixels) are practically not available for aerial mapping, digital image collection systems are mostly restricted to time critical applications as well as mapping of linear features. This is one of the research areas that will need more attention in the future. Laserscanners are being used for surface reconstruct ion and DRM generation. They are in the prototype stage and are promising tools for real- time orthophoto production. There are also interesting developments going on to install digital cameras in the wing-tips of airplanes to take stereo-image pairs of powerlines. The position and orientation of the airplane is determined by 3 GPS antennas. Vehicle Navigation Applications: a number of infrastructure mapping systems have been developed over the past years. They are based on the integration of GPS and INS for positioning vehicles continuously. Different imaging sensors are available for video-logging and attribute collection, as well as stereo-vision systems for spatial 519 positioning of objects in the environment of highways. Data collected with these systems are immediately stored in a GIS. Other research deals with autonomous vehicle navigation. Image sequences are analyzed by tracking points and linear features along the road to estimate the vehicle's motion and speed. On-line triangulation techniques, such as Givens transformations, and 3D Kalman filters are applied. In this category we also include the developments in the IVHS (intelligent vehicle highway systems) field. They mostly deal with the installation of moving map displays and traveler information systems in cars and trucks, to show the position of the vehicle in real-time on a digital map. Integration of GIS and Image Analysis: the integration of GIS data is very useful for automatic, digital image analysis. This is especially true in real-time environments, where different sensors are available that can support image analysis. Automation is a must in such an environment and can only be achieved by proper interfaces. Multi-media, spatial data-bases enhanced by different types of digital imagery provide valuable information in this endeavor. Working Group II/I News * Development of a report/bulletin on sensor and GIS integration is on-going. It will probably be completed for the Symposium in June 1994. * A survey is being conducted on the state-of-the-art in real-time mapping, including the activities of different institutions and Commercial companies world-wide. * Two technical sessions will be organized at the ISPRS Commission II Symposium in Ottawa, Canada (June 1994).
