When a user drags or slides the electronic map through the display interface, a comparison point is preset on the display interface, and after the dragging or sliding operation is finished, a point on the electronic map, which is overlapped with the comparison point, is used as an information cache reference point. By way of example, when a user caches map annotation information through a 200 × 600 display interface, a midpoint (100,300) of the display interface is used as a comparison point, and when a point where the comparison point (100,300) is overlapped in the electronic map after the user drags or slides the electronic map is a point B, the point B is an information cache reference point.
In step S602, according to a preset first rule, a map annotation information cache region corresponding to the coordinates of the information display reference point is determined.

In step S902, a map annotation information cache region corresponding to the map region displayed in the information display window is determined according to a preset second rule.
In the embodiment of the present invention, the preset second rule may be that a map area displayed in the display window is used as a center, a certain number of extension blocks are extended to the periphery, and a block corresponding to the map area and the extension blocks form a cache area of the map annotation information. In the embodiment of the present invention, the number of the blocks expanded to the periphery may be 1 block, 5 blocks, or 10 blocks, and the like, which is not limited specifically, and may be selected according to the size of the map.

In the embodiment of the invention, the map area displayed in the information display window is determined, and the map marking information cache area corresponding to the map area displayed in the information display window is determined according to the preset second rule, so that a user can acquire the map marking information area which can be displayed by the intelligent terminal through the intelligent terminal, and simultaneously can prestore the map marking information which is not the map marking information area which can be displayed by the intelligent terminal, so that the map marking information can be used by the user, the service level of a product is increased, and the use experience of the user is improved.
