The GMRT Online Archive now houses over 120 terabytes of interferometric
observations obtained with the GMRT since the observatory began operating as a
facility in 2002. The utility of this vast data archive, likely the largest of
any Indian telescope, can be significantly enhanced if first look (and where
possible, science ready) processed images can be made available to the user
community. We have initiated a project to pipeline process GMRT images in the
150, 240, 325 and 610 MHz bands. The thousands of processed continuum images
that we will produce will prove useful in studies of distant galaxy clusters,
radio AGN, as well as nearby galaxies and star forming regions. Besides the
scientific returns, a uniform data processing pipeline run on a large volume of
data can be used in other interesting ways. For example, we will be able to
measure various performance characteristics of the GMRT telescope and their
dependence on waveband, time of day, RFI environment, backend, galactic
latitude etc. in a systematic way. A variety of data products such as
calibrated UVFITS data, sky images and AIPS processing logs will be delivered
to users via a web-based interface. Data products will be compatible with
standard Virtual Observatory protocols.
