Abstract

La présente invention se rapporte au domaine de l'informatique. L'invention concerne un procédé d'affichage d'informations d'annotation de carte, un dispositif, un terminal et un support de stockage lisible, le procédé comprenant les étapes consistant à : déterminer, d'après une demande d'utilisateur de visualiser des informations d'annotation de carte, une région de cache d'informations d'annotation de carte, ladite région comprenant au moins un bloc de région de cache d'informations d'annotation de carte ; si l'on détermine que des informations d'annotation de carte correspondant au bloc de région de cache d'informations d'annotation de carte sont mises en cache dans un terminal, afficher les informations d'annotation de carte mises en cache à l'attention de l'utilisateur ; et si l'on détermine que les informations d'annotation de carte du bloc de région de cache d'informations d'annotation de carte ne sont pas mises en cache dans le terminal, acquérir les informations d'annotation de carte correspondant au bloc de région de cache d'informations d'annotation de carte et les afficher à l'attention de l'utilisateur. La présente invention permet de rechercher et de stocker des informations de localisation cible. Ainsi, lorsque l'utilisateur utilise une fonction de carte électronique pour rechercher et stocker les informations de localisation cible, les données de cache inutiles devant être acquises par un terminal intelligent sont réduites, la charge de fonctionnement du terminal intelligent est réduite et la souplesse de fonctionnement du terminal intelligent est améliorée.
