| Abstract: |
The services developed by the Centre de Données astronomiques de Strasbourg (CDS) will play a major role in the cross-identification of objects from large surveys. SIMBAD provides the identification of objects published in the literature, or from reference catalogues; the VizieR catalogue browser can be used to browse through the survey result catalogues, and to compare them to other catalogues and published tables, and the ALADIN sky atlas allows one to overlay survey catalogues on images of the sky, together with SIMBAD, NED, and catalogues and published tables from VizieR. Several aspects of the recent CDS development pave the way to this usage of the CDS services: the inclusion of TYCHO in SIMBAD, the implementation of the public DENIS and 2MASS catalogues in VizieR, and the release of the ALADIN Java interactive tool. The ESO/CDS data mining project, and the AstroGLU discovery tool, aim at providing advanced tools for cross-identification and access to distributed, heterogeneous information. The development of generic tools, such as the CDS GLU system (Générateur de Liens Uniformes), and the definition of standards for information exchange, in cooperation in particular with the archive providers and the journals, and in the frame of project such as ISAIA or DYNACORE, are also keys to provide 'clever' and 'transparent' links between all the information needed for the scientific interpretation of observations. |
