Abstract (en)
[origin: WO03098151A1] The invention relates to a method for compressing and decompressing data of different information contents, e.g. topographic nodes and edges as well as attributes thereof. According to the invention, the degree of compression is configurably formed according to the information content. When compressing, attributes are omitted, the precision of the topographic information is limited or the degree of compression is controlled by means of a predetermined maximum volume of data.
