TL;DR
This paper discusses the challenges and considerations for handling extremely large spectral-imaging data-cubes from modern radio telescopes, evaluating the applicability of JPEG2000 standards for such data management.
Contribution
It provides an analysis of the requirements for large SIDC and assesses the suitability of JPEG2000 standards for contemporary radio astronomy data.
Findings
JPEG2000 may address some challenges of large SIDC
Identifies specific requirements for handling Petabyte-scale data
Highlights potential limitations of current standards
Abstract
The new widefield radio telescopes, such as: ASKAP,MWA, LOFAR, eVLA and SKA; will produce spectral-imaging data-cubes (SIDC) of unprecedented volumes in the order of hundreds of Petabytes. Servicing such data as images to the end-user 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.
