Extremely Large Images: Considerations for Contemporary Approach

Abstract

The new wide-field radio telescopes, such as: ASKAP, MWA, LOFAR, eVLA and SKA; will produce spectral-imaging datacubes (SIDC) of unprecedented volumes in the order of hundreds of Petabytes. Servicing such data as images to the enduser may encounter challenges unforeseen during the development of IVOA SIAP. We discuss the requirements for extremely large SIDC, and in this light we analyse the applicability of approach taken in the ISO/IEC 15444 (JPEG2000) standards.
