The Call for Papers is now out for the 6th International Symposium on Digital Earth (ISDE6), that will be held next September in Beijing, China. It might be a little expensive for a lot of you, but I know that we got to see some great presentations at ISDE 5 in Berkeley, California last year. The theme for next year’s symposium is Digital Earth in Action, and with ISDE’s focus on important social topics like sustainability, it should be a great conference.
