Astronomical data avalanche • Breakthrough in telescope, detector and computer technology allow astronomical instruments to produce terabytes of images and catalogs. This datasets will cover the sky in different wavebands • In a few years it will be easier to “dial-up” a part of the sky than wait many months to access a telescope Besancon, Apr 22, 2008
Virtual Observatory • Over the past years the concept of the Virtual Observatory has emerged rapidly to address the data management, analysis, distribution and interoperability challenges • The VO is a system in which the vast astronomical archives and databases around the world, together with analysis tools and computational services are linked together into an integrated facility Besancon, Apr 22, 2008
Virtual Observatories • Sixteen VO projects are now funded through national and international programs, and all projects work together under the International Virtual Observatory Alliance to share expertise and develop common standards and infrastructures for data exchange and interoperability • A number of the VO projects are using science prototypes, or demonstration projects to show the user community the benefits of the federated archives, catalogs and computational services Besancon, Apr 22, 2008
Additional Informationhttp://www.ivoa.net/pub/info/ • The IVOA (R. J. Hanisch & P. J. Quinn) • IVOA Guidelines for Participation (R. J. Hanisch & P. J. Quinn) • Documents and Standards Besancon, Apr 22, 2008
Standards are necessary • providing access for 103 users to 107 resources of 10 kinds of permission • translation of names to universal dictionary (40-50 designations for Sirius or Vega, 250 different names for Johnson V-magnitude) • names of sources like "gcvs.sternberg.on-line" • query language, resource discovery, resource ranking, specific information (filters, instruments, detectors, image quality etc.), units standardisation Besancon, Apr 22, 2008
What is VO? • We will bring astronomical data from any telescope in the world to any computer, any time, anywhere.Parts of VO are ready now. A grand world wide scheme: 5-10 years.Less than one Advanced Tactical Fighter aircraft. When it will be ready? What will it cost? Besancon, Apr 22, 2008
