ABSTRACT:
A computer-implemented data sorting method for sorting data at high speed with small memory capacity. The sorting method sorts an array of data where sorted data is constituted by a combination of a plurality of blocks where each block is produced separately from one another during the sorting process. In another aspect, a navigation method and system utilizes the data sorting method for quickly sorting and displaying requested information such as POIs sorted by distance with use of a small memory.
