Earth Remote Sensing Data Analysis Center (ERSDAC) ERSDAC accelerates the research and development of remote sensing technology to be applied to exploration for non-renewable resources as well as environmental monitoring on a global scale. For ASTER, ERSDAC implements ASTER Science Project and ASTER GDS Project. http://www.ersdac.or.jp/ ASTER GDS Project Access to learn the outline of ASTER GDS (ASTER Ground Data System).
