Abstract

As sensor technology evolves into the 21st Century, the volume of data available from both airborne and spaceborne sources will increase rapidly. High resolution hyperspectral remote sensing systems may offer hundreds of bands of data. Efficient use, transmission, storage, and manipulation of such data will require some type of bandwidth compression. Current image compression standards are not specifically optimized to accommodate hyperspectral data. Nonetheless, users who require such compression will be driven toward current standards for reasons of simplicity, cost, and interoperability. This paper begins an examination of the performance of the MPEG-like video compression methodologies for hyperspectral image data. Compression fidelity is examined with an objective metric as a function of the achieved compression ratio. Comparisons are made between different coding configurations which resemble those available in the basic MPEG scheme. Observations regarding the use of standards-based compression of hyperspectral data are offered along with suggestions for future investigations.
