Data compression is used to reduce the volume of digital data to achieve benefits in areas including, but not limited to:
- reduction of transmission channel bandwidth;
- reduction of the buffering and storage requirement;
- reduction of data-transmission time at a given rate.
The characteristics of instrument data are specified only to the extent necessary to ensure multi-mission support capabilities. ISO 18381:2013 does not attempt to quantify the relative bandwidth reduction, the merits of the approaches discussed, or the design requirements for encoders and associated decoders.
ISO 18381:2013 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.
