This International Standard defines a data compression algorithm that is applied to digital three-dimensional image data from payload instruments, such as multispectral and hyperspectral imagers, and specifies the compressed data format. Data compression is used to reduce the volume of digital data to achieve benefits in areas including, but not limited to, a) reduction of transmission channel bandwidth, b) reduction of the buffering and storage requirement, and c) reduction of data-transmission time at a given rate. This International Standard specifies the characteristics of instrument data only to the extent necessary to ensure multi-mission support capabilities. It does not attempt to quantify the relative bandwidth reduction, the merits of the approaches discussed, or the design requirements for encoders and associated decoders. This International Standard addresses only lossless compression of three-dimensional data, where the requirement is for a data-rate reduction constrained to allow no distortion to be added in the data compression/decompression process. The scope and field of application are furthermore detailed in subclauses 1.1 to 1.3 of the enclosed CCSDS publication.
