Abstract

L'invention concerne un procédé et un dispositif permettant de fournir des renseignements de manière automatique avec un moteur de recherche. Les objets recherchés qui comportent une caractéristique générique prédéterminable, telle que la branche, etc. et se situent à l'intérieur d'une zone pouvant être prédéfinie par des données cartographiques telles que la longitude et la latitude, sont déterminés et des données d'identification desdits objets, telles que nom, numéro de téléphone etc. peuvent être transmises de manière automatique à un dispositif d'affichage, notamment un téléphone mobile et/ou être fournies sous forme consultable. Selon l'invention, il est prévu d'effectuer une première demande de recherche auprès d'une banque de données GIS, afin d'obtenir en ce qui concerne la zone recherchée, déterminée par des données cartographiques telles que la longitude et la latitude, des données concernant l'adresse, telles que le lieu, la rue, le code postal, etc. correspondant aux adresses situées dans cette zone. Sur la base des données obtenues qui portent sur les adresses de la zone recherchée, une seconde demande de recherche est dirigée vers un fichier non codé de manière cartographique, notamment un annuaire téléphonique ou classé par branches à l'échelon national, afin d'obtenir tous les objets et les données d'identification d'objet correspondantes, qui satisfont à la caractéristique générique prédéterminable et comportent une adresse coïncidant avec les données d'adresse déterminées au préalable. Ce système permet de fournir des renseignements propres au lieu, même s'ils proviennent d'un fichier non cartographique.
