Abstract: A method and a system for systematic encoding of network of roads in a geographical area retrieves road data of the network of roads from one or more data sources and normalizes the road data to divide each road based on predefined first parameters. Thereafter, the encoding system divides the geographical area including the network of roads into clusters based on predefined second parameters. Now, the encoding system selects a major road in each of the clusters and creates sub-clusters from the clusters until the major road satisfies certain limits such as a first limit and a second limit. Finally, the encoding system encodes each major road and the corresponding incident roads contiguously or near contiguously in accordance with the clusters such that the encoding is contiguous, systematic and accurate.
