China-VO• Virtual Observatory (VO) is a data-intensively online astronomical research
and education environment, taking advantages of advanced information technologies to achieve seamless, global access to astronomical information.
• Chinese Virtual Observatory (China-VO) is the national VO project in China initiated in 2002 by Chinese astronomical community leading by National Astronomical Observatories, Chinese Academy of Sciences.
• China-VO became a member of the IVOA with the recommendation of Dr. Jim Gray
• China-VO Platform • Unified Access to On-line Astronomical Resources and Services • VO-ready Projects and Facilities • VO-based Astronomical Research Activities • VO-based Public Education
R&D Focuses
