Defining "correct" initial location descriptions can be difficult. Maintenance of the database of descriptions in the GLB can be a time-consuming task.

Abstract

La présente invention concerne un procédé de traitement des données géographiques lesquelles sont divisées en au moins deux types principaux: un premier type (Zone) représenté par un polygone irrégulier constitué de noeuds définis chacun par au moins deux coordonnées (Xn, Yn), et un second type (Point), représenté par des données qui contiennent au moins deux coordonnées (Xp, Yp), le premier type présentant également un niveau d'informations géographiques spécifiées par une étiquette. Le premier type comprend un centre et un rayon maximal, ledit centre (C) représentant le centre d'un cercle tracé autour des noeuds les plus à l'extérieur, et le rayon maximal représente le rayon (R) du cercle. Ce procédé consiste à rechercher dans chaque groupe demandé du second type de données (Points) la position des seconds types adjacents, cette recherche consistant en une recherche approximative dans laquelle on compare la distance entre la position dudit second type de données et ledit centre de chaque premier type de données aux rayons de « P » et « C ».
