The BIG Picture Earth Observing Systems (EOS) and the Global Earth Observing System of Systems (GEOSS) Dorsey Worthy U.S. EPA, Office of Research and Development National Exposure Research Laboratory

EOS environmental remote sensing systems can provide near-continuous monitoring of the earth The GEOSS "system-of-systems” of remote and ground-based sensors and monitoring activities will enable unprecedented access to and use of earth resources data and information EOS and GEOSS global
