In the past 20 years, China has made great achievements in spatial technologies development and application. Remote sensing, geography spatial technology, and global positioning system are employed to monitor and predict various disasters (flood, drought, fire, red tide, typhoon, landslide, sand storm, and so on), and to monitor and evaluate environmental qualities (aerosol, water pollution, and ecological environment). To realize large scale, dynamic, all-weather, real time monitoring of disaster and environment, China will lunch a moonlet constellation composed of 4 optical satellites and 4 SAR satellites before 2010. Meanwhile, ground-based system and application system will also be constructed. A space-ground integrated framework for disaster and environment monitoring, relieve, decision-making, and managing is expected in the near future.
