Abstract：Nowadays, "3S" technologies have played an important role in socio-economical development.In the following years two satellite navigation/positioning systems, GPS and GLONASS, will be replaced as new satellites and techniques to improve accuracy and ability of anti-interference.The European Galileo system, in which China has joined, will be completed in 2010, and as a result that the GPS monopolizes market of satellite navigation/positioning in the world could be broken.The remote sensing technology will be developed towards high resolution, multi-platform, quantification, network and application.The technology of geographic information system will be developed with computer science, and be extremely paid close attention to the analysis and presentation of 3-D spatial data, the spatial data uncertainty, the integration or fusion of multi-source data, and the spatial multi-scale data mining etc., and also developed towards network and popularization, as well as become an important part of geographic information industries.
