Since the beginning of the IEEE GRSS society founded 54 years ago and the first IGARSS held in 1980, the GRSS tradition has been making our symposium worldwide. This is not only because of the global nature of our society, i.e. geosciences and remote sensing related, but also the GRSS leaders have an open mind to foresee fast advancement of remote sensing all over the world. We are very pleased that this time is our turn, Beijing will host you all!
