Abstract

La présente invention peut améliorer la commodité pour un usager d'une installation intérieure. Un système d'affichage de carte 1 comprend : un terminal utilisateur 3 pour un utilisateur qui utilise une installation intérieure dans laquelle une pluralité de symboles sont installés; et un serveur de gestion 2 qui peut communiquer avec le terminal utilisateur 3. Le terminal utilisateur 3 acquiert des données d'image photographiée obtenues en photographiant les symboles. Le serveur de gestion 2 stocke des données d'une image de carte qui représente des sentiers dans l'installation intérieure ainsi que des données de carte comprenant des données d'une pluralité de nœuds agencés sur les sentiers. Un emplacement actuel est établi sur la base d'une image d'un symbole inclus dans les données d'image photographiée, un nœud quelconque parmi la pluralité de nœuds est établi en tant que destination, un trajet de déplacement menant de l'emplacement actuel à la destination est généré, et des informations de guidage indiquant le trajet de déplacement sont délivrées. La pluralité de nœuds comprennent : une pluralité de nœuds généraux qui ne correspondent à aucun symbole parmi la pluralité de symboles; et une pluralité de nœuds de symbole qui correspondent respectivement à la pluralité de symboles. De plus, le nombre de nœuds de symbole est inférieur au nombre de nœuds généraux.
