Abstract

La présente invention concerne un système de collecte et de fourniture d'informations de carte qui est capable de collecter efficacement des images locales et des informations de carte tout en étant capable de réduire les coûts. Un moyen d'entrée d'informations (32) qui est capable de fournir en entrée des informations de changement est prévu dans un terminal utilisateur (14). Un moyen de mise à jour d'informations de carte (54) est prévu dans un centre de traitement de l'information (18). Si les informations de changement reçues en provenance du terminal utilisateur (14) sont des informations montrant qu'il existe un changement, le moyen de mise à jour d'informations de carte (54) reçoit une image d'utilisateur et des informations de position de collecte d'image d'utilisateur qui sont associées aux informations de changement, en provenance du terminal utilisateur (14) ; remplace une image de centre de traitement de l'information associée aux informations de position de collecte d'image de centre de traitement de l'information qui a des informations de position identiques aux informations de position de collecte d'image d'utilisateur, par l'image d'utilisateur reçue ; et stocke celle-ci dans un moyen de mémoire (52).
