<p>The method involves determining a geographical zone (18) from a map (16) with a predetermined level of granularity containing an entity (10). A change of zone is detected as a function of geographical coordinates of a monitored entity. A new level of granularity is applied as a function of operational destination zones (24a, 24b). The granularity level and the geographical zone determination steps, the zone change detection step and the granularity level application step are independently carried out within each entity without outside communications when the operational zone is changed. An independent claim is also included for an entity moving in a monitored space represented by a digital model.</p> |
