MegaCities

摘要

Remote-sensing satellites are a truly gl9obal tool for addressing 'global challenges' and 'global concerns'. To increase public, political and industrial awareness of their real potential, the ESA Technology Transfer Programme office chose to support the United Nations' 'Urban 21' Programme, and as part of that initiative the MegaCities book project. The goal in collecting scenes from as many satellites as possible to show the prevailing situations of 42 'MegaCities' around the World, including potential threats and hazards, was to contribute to a better understanding of the global challenge that they pose.
