Dear Colleagues,

You are cordially invited to attend the 6th International Symposium on Digital Earth ( ISDE6 ) with the theme of Digital Earth in Action and to visit Beijing, China in September, 2009. ISDE6 will continue the tradition of gathering world-class scientists, engineers and educators to review the progress of digital earth during the last decade and discuss the achievements of digital earth and its future development.

Digital earth is a virtual representation of our planet and a global initiative aimed at harnessing the world's data and information resources to develop a virtual 3-D model of the Earth in order to monitor, measure, and forecast natural and human activity on the planet. It has a broad domain related to earth observation, geographic information system, global positioning system, virtual reality, computer technology, network communication, geosciences and social sciences etc.

Since the promulgation of the Beijing Declaration on Digital Earth at the First International Symposium on Digital Earth (ISDE) in 1999, digital earth has prospered and made great progress in both theory and applications. The international symposia on digital earth have been held in Canada, Czech Republic, Japan, and the United States every two years since 2001, and Digital Earth Summits were convened in New Zealand and Germany in 2006 and 2008 respectively. The 6th ISDE "Digital Earth in Action" will mainly focus on the technological advances and the various emerging applications linking digital earth and many other relating technologies.>>>
