The Compression of Digital Terrain Elevation Data (DTED) Using JPEG2000

Abstract

This report summarises the results of an investigation of the applicability of the JPEG20O0 compression system to Digital Terrain Elevation Data (DTED) and in particular the application of the region-of-interest, ROI, capabilities built into the standard. JPEG2000 is a new image compression standard offering a number of advantages, particularly relevant to Defence, over previous image compression standards. Its application to DTED would not normally be considered, given that DTED is not an imagery data type. However DTED has similar characteristics to monochrome imagery data and the utility of JPEG2O00 and in particular ROI capability would have benefits for the storage and dissemination of DTED within Defence. The advantage of ROI coding is that very high compression ratios can be achieved while maintaining high fidelity of the data in regions of importance. Possible applications of such techniques would be in the distribution or dissemination of DTED, or mission rehearsal products containing elevation data, to deployed units where they could be used to support tactical mission planning and rehearsal.
