  1. Data Resources and Services at Chinese Astronomical Data Center ChenzhouCui, Boliang He Chinese Virtual Observatory (China-VO) National Astronomical Observatory of China

  2. 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 R&D Focuses • 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

  3. China-VO Team Partners • NAOC (Beijing): Yongheng Zhao (PI), Chenzhou Cui (PM), Ganghua Lin, Yanxia Zhang, Boliang He, Wei Gao, Yue Chen, YimingTeng, Zihuang Cao, Dongwei Fan, Wangwei Chu, HaijunTian, Zheng Li, • TianJin Univ.

  4. Data Access Services

  5. Database Factsheet • Database • PostgreSQL 9.1.x + pgSphere • Web Visualization • VOTable Search Result -> Aladin Plot • Image Fits -> Aladin Plot

  6. Data resources at the CAsDC From China • LAMOSTPilot Data Release • LAMOSTCommission Data • The South Galactic Cap U-band Sky Survey (SCUSS) • CSTAR • BATC • LAMOST Sky Survey • Xinjiang radio telescope (25m) • Lijiang 2.4m telescope • Bootes-4robotic observatory • Astronomical plates digitalization archive Mirrors of international archives CDS Vizier SDSSSkyServer 2MASS WISE Chandra UCAC USNO ADS

  7. VO Standards supported • VOTable • Simple Cone Search • http://service.china-vo.org/scs/ • TAP Service • http://service.china-vo.org/tap/ • Aladin embedded • Search on lists/SQL • User space

  8. LAMOST Pilot Sky Survey From 2011-10 to 2012-4 Plan: 305, Run: 312 Spectra: 484,185 + low SN <160,000 Spectra Catalog 478,699

  9. 2.3M BOK Telescope of Steward observatory on Kitt Peak

  10. The South Galactic Cap U-band Sky Survey (SCUSS) • From 2010~2013 • Publish: • 1579 Field (1 deg^2 per field) • 21,437,427 Object Catalog Search Web Form Search SQL Search Image Search and Aladin Plot The observation progress of SCUSS until end of 2011. About 2000/3700 square degree covered and 300+450 Galactic anti-center area

  11. Cross Comparison In Aladin Uband+SDSS Uband+SDSS+WISE

  12. Plans in the near future • Petabyte scale archive challenges research • Register these services to the IVOA registry • Data federation with Vizier mirror in Beijing • SSA for LAMOST pilot sky survey • SIA for SCUSS/CSTAR images • Interfaces for the public (WWT)

  13. Active Community Involvement • IVOA • World Data System (WDS) • CODATA • Data at Risk Task Group • Chinese astronomical plate digitalization project • Astronomical key projects and e-Science community

  14. Thank You
