《第三届国际未来智能对地观测会议文集(英文版)》:The real-time acquisition and intelligent processing has emerged as an important trend of future Earth observation technologies. The international symposia on Future Intelligent Earth Observing Satellites (FIEOS) were previously hosted in Denver, Colorado, USA in 2002 and Istanbul, Turkey in 2004. The new technologies for future Earth observation, such as onboard processing systems, sensor integration, data processing and communication, and applications of satellite data, as presented in the previous symposia, are highlighted widely now. The 3rd Intemational Symposium of FIEOS (FIEOS 2006), held during 24-26 May, 2006 in Beijing, China, provided a good exchange platform for experts from all over the world to share their experience in the field of Earth observation technologies and applications.
