Abstract
Due to the large volume of Earth science data projected to be collected froms pace platforms over the next several years, Earth science data information systems will be facing significant problems in data transmission, storage, and dissemination. Data compression is one tool that can be used to overcome these problems; however, no single data compression approach is likely to be appropriate for all aspects of this problem. The data compression approaches employed must be tailored appropriately for each particular aspect of the information system. We describe here several data compression approaches that show promise for application to one or another aspect of the information system. We then highlight selected current attempts to apply data compression techniques to particular aspects of the Earth science data information system. We conclude by stating our belief that data compression technology will not only help the Earth science community deal more effectively with their data volume problem, but, if applied in the most appropriate manner, will also serve to enhance the collection, distribution, analysis, and overall scientific worth of Earth science data.
