Abstract

L'invention concerne un procédé d'intégration et d'affichage d'informations spatiales générées par des traitements ou des applications. Ce procédé est mis en oeuvre de la façon expliquée ci-dessous. (1) Dans une application, sont gérés des traitements dont chacun génère des informations spatiales, les informations spatiales, un traitement d'intégration servant à l'intégration des informations spatiales et à la génération d'informations intégrées, les informations intégrées, ainsi qu'un traitement d'affichage servant à l'envoi des informations intégrées à une unité de sortie. Ainsi les informations spatiales générées par les traitements sont intégrées et affichées par une application. (2) Pour la mise en oeuvre d'un procédé de transfert des résultats de sortie d'un traitement de génération d'informations spatiales à un traitement d'intégration, on utilise une communication inter-processus, une communication inter-clients par l'intermédiaire d'un système de fenêtre, ou bien une mémoire commune. Dans une variante, un fichier est utilisé comme support. Ainsi, les informations spatiales générées par les applications sont intégrées et affichées. (3) Les informations spatiales sont affichées en surimpression en mode transparent. Cela permet de percevoir les informations spatiales générées par les traitements ou les applications d'un seul coup d'oeil.
