Geocoding method for digital road network system, involves dividing initial zone to obtain sub-zones, where dividing phase is recursively performed by generating small sub-zones according to reduction criteria till stop threshold is reached

摘要

The method involves dividing an initial zone to obtain N sub-zones for a given zone containing points of interest to be re-geocoded, where size of the obtained sub-zones is optimized. The points of interest of each sub-zone are spatially-indexed. The dividing phase is performed in a recursive manner by generating small geographical sub-zones according to reduction criteria until a stop threshold is reached. An independent claim is also included for a software comprising program code elements for implementing a geocoding method.
