Method for managing a system of geographical information adapted for use with at least one pointing device, with creation of associations between digital objects

摘要

A method is proposed for managing a geographical information system adapted for use with at least one pointing device. The geographical information system includes a central unit accessing a data base containing a plurality of digital objects. Each digital object possesses an identifier and is defined in the data base by a geometrical component defining a geographical position and by a descriptive component defining at least one descriptive attribute. The central unit is adapted for determining, as a function of the geometrical components of the digital objects and of information on the position and orientation of a given pointing device, whether the position of one of the digital objects is being pointed at by the given pointing device. The central unit carries out a step of creating an association between at least two digital objects contained in the data base, in order to form a group of associated digital objects.
