Please select the most similar patent number from A, B, C and D. Which number is?
An electronic map implementation method, device, storage medium and equipment, the method comprising: obtaining at least one influencing parameter corresponding to the area scope of the electronic map (110); according to the influencing parameter, determining recommended points of information within the area scope of the electronic map (120); displaying the points of information on the electronic map (130). The electronic map implementation method, device, storage medium and equipment determine recommended points of information via at least one influencing parameter to recommend to users, thus providing travelling reference information in multiple aspects for the users, recommending to users places suitable for travelling, and reducing the impact of planned travelling places results on travelling of users.
A: Disclosed is an information recommendation method and device, a mobile terminal and a storage medium. The method comprises acquiring location information uploaded by the mobile terminal, determining a corresponding venue according to the location information and map data; determining corresponding recommendation information according to venue information and a stored recommendation data set; sending the recommendation information to the mobile terminal.
B: The present invention provides a method, apparatus and device for presenting an electronic map, and a nonvolatile computer storage medium. In an embodiment of the present invention, personalized setting information of at least one map element on an electronic map is acquired, and then presentation information of the at least one map element is obtained according to the personalized setting information. Because the presentation information of the map element can be obtained according to the personalized setting information, a rendering engine can present the map element according to new presentation information. In this manner, the electronic map presented by the rendering engine has multiple flexible variable modes rather than a single mode. The problem that because a rendering engine can only present the electronic map according to preset presentation information of the map element in the prior art, and the presented electronic map pattern is relatively fixed is solved, thereby improving the presentation flexibility of the electronic map.
C: A method, device and apparatus for processing a high-precision electronic map, and a computer-readable storage medium. The method comprises: obtaining a high-precision electronic map obtaining request provided by a user, the high-precision electronic map obtaining request comprising a requested high-precision electronic map identifier (101); obtaining a high-precision electronic map file according to the high-precision electronic map identifier, the high-precision electronic map file comprising at least two groups of encryption map elements (102); decrypting the at least two groups of encryption map elements to obtain at least two groups of original map elements (103); and obtaining a high-precision electronic map requested by the user according to map element semantic information and the at least two groups of original map elements (104). Due to the encryption method of grouping map elements instead of the overall encryption method of files, the difficulty of decrypting high-precision electronic maps is greatly increased, thereby improving the security of high-precision electronic maps.
D: The present application provides a method and device for drawing roads in an electronic map. The method comprises: a map server receives position information of an acquisition point transmitted by a mobile terminal, the position information being acquired by the mobile terminal at the acquisition point through positioning; and the map server draws roads in a first area of the electronic map according to the position information of the acquisition point comprised in the first area of the electronic map and transmitted by the mobile terminal. The embodiments of the present application further provide relevant devices. In the embodiments of the present application, the mobile terminal is used as an acquisition device to acquire the position information of the acquisition point; a low-cost and simple method for drawing roads in the electronic map is provided; and real-time updating of the electronic map can be realized.
