  1. Development ofChina-VO ZHAO Yongheng NAOC, Beijing Nov. 2003

  2. Contents • China-VO • Bases • Design • Applications • Future Plan

  3. China-VO • Advanced research platform for Chinese astronomers • Acquire data and technologies from IVOA partners • Share our data (LAMOST, SST, FAST, BATC …) with international astronomers • Bring up a group of VO-oriented astronomers, engineers and students • Education outreach

  4. Highlights Sep. 2001: VO meeting in China July 2002: Concept of “Chine-VO” Oct. 2002: member of IVOA June 2003: System design finished (based on OGSA/Globus) • Cui’s doctoral dissertation Sep. 2003: VO meeting in China • Technology progress • Cone Search Service (2003) • Abundance gradients in the Galaxy statistical research (2003) • Auto-classification using multi-wavelength archives (2004)

  5. Funding • 400,000 RMB (~50,000 USD) • Collaboration • WDC-D • CNGrid project (CNIC) • Xinglong Station (NAOC) • LAMOST project (NAOC)
