STUDY & ANALYSIS ON USING JPEG2000 COMPRESSION STANDARD WITH HIGH RESOLUTION GEOSPATLAL IMAGERY PRODUCTS

Many SurveyinglGeomatics related organizations are in the process of conslructing huge high￾resolution imagery databases which contain digid color images covering different areas of their
interest. The sues of such image databases are very large A typical problem of such database
projects IS the huge size of the imageq for storage andlor distribution. With the development of
remote sensing technology, large swath width along with multi-wavebands make data size to
mcrease greatly. Therefore, image compression becomes one of the most essential tasks in dealing
with such imagery. Several techniques exist on the market to compress such imagery The
compression market is now overwhelmed by Standard & non-standard compression tools and
software. Each vendor pretends to have the most reliable compression techniques.
This paper is devoted to examine (subjectively and objectively) the effect of using the new
JPEG2000 standard compression algorithm Joint Photographic Experts Group- in the market in
dealing with high resolution spatial imagery & to recommend the optimum compression ratio to be
used when using PEG2000 standard in compressing high resolution imagery. The testing
procedure cons~dered the spectral as well as the spatial effect of the new market standard on the
image pixels and to recommend the optimum compression ratio for such cases.
