Abstract

Cette invention concerne un dispositif d’affichage de plan qui regroupe une pluralité de points et affiche le groupe de points pour permettre à un utilisateur de percevoir leur répartition, un procédé d’affichage de plan et un support d’enregistrement sur lequel est stocké un programme d’affichage de plan. L’emploi de données de plan pour afficher un plan sur un moyen d’affichage et de données de point pour signaler des points sur le plan permet de créer et de produire des données d’image sur le plan où les points sont indiqués. Les données de point comprennent des données représentant les positions des points et d’autres correspondant aux attributs des points. Les points avec les mêmes données de type sont regroupés selon la distance entre eux sur le plan, une zone du plan contenant tous les points du groupe est définie, et des données d’image sur le plan sont créées avec indication de la zone.
