Abstract

Addresses the problem of accessing portions of multiband data which has been losslessly compressed. An approach that uses the fractal property of some well known space filling curves to provide access to portions of a losslessly compressed data set is described. This approach reduces the average amount of decompression necessary to access any portion of the data set, thereby reducing the amount of time required to access the compressed data. Various tradeoffs exist which will be discussed with practical examples
