Main Research Area
Prof. Gong is engaged in the basic research of geographic information theory and geometric remote sensing, and the object-oriented geographic information system models and methods proposed by him in the 1990s has become the current mainstream technology. At the beginning of this century, he systematically proposed the spatial information sharing and interoperability theories and methods, and the developed multi-source spatial information sharing service platform GeoSurf and the network three-dimensional information sharing and integration platform GeoGlobe have become the basic software of China's military and civilian platforms, for example, MAP WORLD, for common geographic information services. In terms of photogrammetry and remote sensing, Prof. Gong proposed a generalized geometric imaging model and precise processing method, and took the chair of the development of a ground processing system for remote sensing satellites, which has greatly improved the autonomous positioning accuracy of domestic remote sensing satellite images. He presided over the design and demonstration of China's first civil stereo mapping satellite-Ziyuan-3, as well as the remote sensing data ground processing system, making the satellite and its application reach the international advanced level. As a result, Prof. Gong won the First Prize of the National Scientific and Technology Progress.
