!!! We will terminate ASTER Products Distribution Service in March 2016 although we have been providing ASTER Products since November 20, 2000. !!! ASTER (Advanced Spaceborne Thermal Emission and Reflection radiometer) is the high efficiency optical imager which covers a wide spectral region from the visible to the thermal infra-red by 14 spectral bands. ASTER acquires data which can be used in various fields in earth science. ASTER was launched from Vandenberg Air Force Base in California, USA in 1999 aboard the Terra, which is the first satellite of the EOS Project. The purpose of ASTER project is to make contributions to extend the understanding of local and regional phenomena on the Earth surface and its atmosphere. The followings are ASTER related information, which includes ASTER instrument, ASTER Ground Data System, ASTER Science Activities, ASTER Data Distribution and so on. ASTER Search provides services to search and order ASTER data products on the website.
The "GEO Grid" project since 2005 is primarily aiming at providing an E-Science infrastructure for worldwide Earth Sciences community. In the community there are wide varieties of existing data sets including satellite imagery, geological data, and ground sensed data that each data owner insists own licensing policy. Also, there are so many of related projects that will be configured as virtual organizations (VOs) enabled by Grid technology. The GEO Grid is designed to integrate all the relevant data virtually, again enabled by Grid technology, and is accessible as a set of services. To dedicate the establishment of such a system, a lot of enthusiastic effort such as that seen in the effort of "The 10-Year Implementation Plan for GEOSS" has been devoted to creating IT platforms where people can access entire integrated data sets and use them to understand the earth more accurately than ever
