Analyse des empreintes guidée par un modèle de connaissances pour la compréhension des dynamiq.

The spatial footprints, historical or acquired in real time, help to understand the dynamics of their carriers. In a context of coastal maritime navigation, the research presented details the approach of setting up a knowledge model aimed at a semantic analysis of ship footprints. This model is defined on the basis of knowledge gathered from experts in this field, supplemented by textual and graphic descriptions. After having described these navigation principles, we present the stages leading to such a knowledge model. The research is completed by the formalization of rules relating to the visibility of landmarks. Finally, a reasoning leads to infer additional navigation knowledge on which the navigation footprints are confronted in order to identify the routes having semantics for the model and those devoid of semantics.
