Abstract:
1. An entity moving in a monitored space represented by a first digital model comprising a set of maps with different levels of granularity representing a requested fineness of the monitoring, each map being divided into geographical zones of a predetermined shape, and having a size defined according to the level of granularity, the entity including: a saving unit for loading a set of data relative to the geographical zones associated with the maps of different levels of granularity, a positioning unit for positioning the entity, so as to determine the geographical coordinates of the monitored entity, and a detecting unit for detecting a change of geographical zone as a function of the geographical coordinates of the monitored entity, the monitored entity going from an original geographical zone to a destination geographical zone, wherein: the saving unit includes a data set relative to operational zones comprising a predefined level of granularity, the detecting unit is capable of independently detecting a change of operational zone, the monitored entity going from an original operational zone to a destination operational zone, and the entity includes a determining unit for independently determining a level of granularity to be applied from the original operational zone, and a new level of granularity as a function of the destination operational zone, in the case of a change of operational zone.
