Abstract

La présente invention concerne un procédé et un appareil pour corriger une position cible dans une carte, un dispositif informatique et un support d'informations lisible par ordinateur. Le procédé de correction d'une position cible dans une carte comprend : l'acquisition d'informations de description de position cible (S202) ; la détermination d'une position cible dans une carte planimétrique selon les informations de description de position cible (S204) ; le passage à une carte de vue réelle et l'acquisition, selon la position cible déterminée dans la carte planimétrique, d'informations de vue réelle depuis une scène de rue affichée dans la carte de vue réelle (S206) ; le renvoi des informations de vue réelle (S208) ; la réception d'informations de description de décalage de position en réponse aux informations de vue réelle (S210) ; la détermination des informations de vue réelle dans la carte de vue réelle selon les informations de description de décalage de position (S212) ; l'utilisation de la position, correspondant aux informations de vue réelle déterminées, dans la carte planimétrique en tant que position cible corrigée (S214).
