Compressing/decompressing data of data stream involves omitting attributes and/or limiting information accuracy and/or specifying maximum data quantity, controlling degree of compression accordingly

摘要

The method involves configuring the degree of compression in accordance with the information content and using at least one of a set of measures for the compression, i.e. omitting certain attributes, e.g. edge identification, limiting the accuracy of the topographical information, e.g. coordinate accuracy, and specifying a maximum data quantity and controlling the degree of compression accordingly.
