Paper Abstract

Remote Sensing and Geographic Information Systems applications are becoming an important issue in research projects, territorial management and many fields of our society. These applications present some special necessities and requirements, using high resolution and hyperspectral images. The huge size of these images implies high computational resources for their processing, storage and, in some cases, high bandwidth channels for their transmission. These disadvantages can be compensated with the use of compression techniques with the capacity to widely reduce this amount of information. Recently, some image compression schemes have been used to develop novel standards and proprietary formats. ECW, MrSID, and JPEG2000 are some of them, presenting advanced features and capabilities that can be used for Geographic Information Systems to extend their functionalities. This work addresses two main topics: first, a review of the most common formats used in Remote Sensing and Geographic Information Systems environments is provided. Secondly the JPEG2000 standard is briefly explained and J2K is presented. J2K is a novel JPEG2000 implementation that allows an easy extension and modification of some coding parameters of the standard, so that an improvement of the compression performance may be achieved for some particular images in GIS scenarios.
