VO-India Project

Started in 2002 as a collaboration between IUCAA and Persistent Systems Ltd. Part of International Virtual Observatory initiative. Supported by a grant by Ministry of Communication and Information Technology,

India.

Objectives Undertake research and development for data search and retrieval. Develop software for equal and efficient use of the data. Enable astronomers and other interested scientists to undertake major scientific projects

using the data. Make the technology available for use by other fields, like remote sensing, population

studies, which involve large amounts of data.
