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.

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