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

China-VO and LAMOST

• LAMOST will select observing objects from VO
• Multi-wavelength sky survey archives, i.e. FIRST,
  NVSS, 2MASS, IRSA , SDSS, POSS
• LAMOST will enhance astronomical spectrum
  resources greatly with its output
• 107 spectra of galaxies
• 107 spectra of stars
• 106 spectra of quasars
