Referring to fig. 1, an interaction between a server 20 and at least one user terminal 10 according to an embodiment of the present invention is shown. In the embodiment of the present invention, the server 20 is in communication connection with the at least one user terminal 10 through a network, and is configured to determine whether to allow the corresponding user terminal 10 to switch the currently displayed electronic map according to the current location information of each user terminal 10. The map engine information of the at least one user terminal 10 is stored in the server 20, and the user terminal 10 displays a map corresponding to the map system through the running map engine, for example, when one user terminal 10 includes a Baidu map engine, a Google map engine, and a high-level map engine, the user terminal 10 may correspondingly display a matched Baidu map, a Google map, or a high-level map by running the Baidu map engine, the Google map engine, or the high-level map engine, and each map engine corresponds to one electronic map.
In this embodiment, if the server 20 determines that a certain user terminal 10 needs to switch a currently displayed electronic map, the server 20 selects optimal map engine information matched with a target area for the user terminal 10 according to target area information corresponding to the user terminal 10 when the user terminal 10 moves, and correspondingly obtains service map layer data of the target area under a map engine corresponding to the optimal map engine information, and then sends the obtained optimal map engine information and the service map layer data to the corresponding user terminal 10, so that the user terminal 10 switches a currently operated map engine to the target map engine matched with the optimal map engine information according to the optimal map engine information, and displays a corresponding map based on the target map engine and the service map layer data, so that the user terminal 10 can switch and display the optimal electronic map corresponding to the target area in real time, so as to improve the user experience, wherein the target area is an area where a target location to which the user terminal 10 goes when crossing the corresponding preset boundary is located. In this embodiment, the user terminal 10 may be, but is not limited to, a smart phone, a Personal Computer (PC), a tablet PC, a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), and the like.
Optionally, please refer to fig. 2, which is a first flowchart illustrating a map switching method according to an embodiment of the present invention. In the embodiment of the present invention, the map switching method is applied to a user terminal 10 and a server 20 that communicate with each other, the user terminal 10 includes a plurality of map engines, and the server 20 stores all map engine information included in the user terminal 10, where each map engine corresponds to one electronic map. The detailed flow and steps of the map switching method shown in fig. 2 are explained in detail below.
In the embodiment of the invention, the map switching method comprises the following steps:
in step S210, the server 20 obtains the location information of the user terminal 10 in real time, and determines whether the user terminal 10 crosses a preset boundary according to the location information.
In this embodiment, the server 20 may obtain the location information of the user terminal 10 in real time by positioning the user terminal 10; the server 20 may also obtain the location information of the user terminal 10 in real time from a third party positioning detection system, wherein the third party positioning detection system may be, but is not limited to, a GPS global positioning system, a beidou positioning system, etc.; the server 20 may also obtain the location information of the user terminal 10 in real time by directly obtaining the location information from the user terminal 10, where the user terminal 10 may obtain the location information of itself through a probe detection system included in itself.
In the present embodiment, the server 20 stores preset boundary information corresponding to the user terminal 10 for communication connection, where the preset boundary information may be, but is not limited to, country boundary information, region boundary information, scenic spot boundary information, indoor and outdoor boundary information, service execution area boundary information, and the like. The preset boundary information stored in the server 20 and corresponding to each user terminal 10 may be different or different, and the specific situation may be set differently by the user corresponding to the user terminal 10 according to the actual requirement.
In this embodiment, the server 20 may obtain the position movement track of the user terminal 10 by analyzing the position information of the user terminal 10 obtained in real time, and determine whether the user terminal 10 crosses the corresponding preset boundary based on the position movement track.
In step S220, when it is determined that the user terminal 10 crosses the preset boundary, the server 20 obtains, according to the target area information of the user terminal 10, optimal map engine information corresponding to the target area information from all stored map engine information, and correspondingly obtains service map layer data of the target area under the target map engine corresponding to the optimal map engine information.
In this embodiment, after determining that the user terminal 10 crosses the corresponding preset boundary, the server 20 may determine a target area where the user terminal 10 crosses the preset boundary according to the position movement track of the user terminal 10. For example, a preset boundary of one user terminal 10 is an indoor and outdoor boundary, a position moving trajectory of the user terminal 10 is from indoor to outdoor, and a target area where the user terminal 10 crosses the preset boundary is an outdoor area.
In this embodiment, after obtaining the target area of the user terminal 10, the server 20 obtains the optimal map engine information corresponding to the target area information according to the target area information corresponding to the target area, and the service map layer data of the target area under the target map engine corresponding to the optimal map engine information. The target area information includes a name, a position, a range, facility information and the like corresponding to the target area, and the service map layer data includes distribution conditions of facilities, streets, traffic and the like of the target area in an electronic map corresponding to a corresponding target map engine.
Optionally, the step of obtaining the optimal map engine information corresponding to the target area information from all the stored map engine information according to the target area information of the user terminal 10 includes:
calculating the map feature integrity of each map engine at the corresponding target area according to the target area information;
and comparing the map feature integrity corresponding to each map engine, and selecting the map engine information corresponding to the map engine with the maximum map feature as the optimal map engine information corresponding to the target area information.
The map feature integrity can represent a map display condition corresponding to the target area of the corresponding map engine, and the electronic map corresponding to the map engine in the target area is more accurate when the numerical value of the map feature integrity is larger.
In step S230, the server 20 sends the optimal map engine information and the service map layer data to the user terminal 10.
In this embodiment, the server 20 may send the optimal map engine information and the service map layer data corresponding to the user terminal 10 to the corresponding matched user terminal 10 based on a network.
In step S240, the user terminal 10 receives the optimal map engine information and the service map layer data, and determines whether the currently running map engine is a target map engine corresponding to the optimal map engine information.
In this embodiment, after receiving the optimal map engine information and the service map layer data sent by the server 20, the user terminal 10 determines whether the currently running map engine of the user terminal 10 is the target map engine corresponding to the optimal map engine information by matching the currently running map engine with the optimal map engine information.
In step S250, if the currently running map engine is not the target map engine, the user terminal 10 switches the currently running map engine to the target map engine, and displays a map corresponding to the target area based on the service map layer data and the target map engine.
In this embodiment, if the currently running map engine of the user terminal 10 is not matched with the optimal map engine information, the user terminal 10 determines that the currently running map engine is not the target map engine, and switches the currently running map engine to the target map engine, so as to display a map of a corresponding target area based on the service map layer data and the target map engine, thereby implementing real-time switching display of an optimal electronic map corresponding to the target area, and improving user experience.
Optionally, the step of switching the currently running map engine to the target map engine by the user terminal 10, and displaying the map of the corresponding target area based on the service map layer data and the target map engine includes:
storing user data and service data displayed on a currently running map engine, and carrying out adaptation adjustment on the target map engine according to a preset engine adaptation standard to obtain an adapted target map engine;
and restoring and displaying the stored user data and the stored service data on the adapted target map engine, and correspondingly loading and displaying the service map layer data on the adapted target map engine so as to display the map of the target area through the target map engine.
In this embodiment, the map engines running on the user terminal 10 are all map engines adapted and adjusted based on a preset engine adaptation standard, and the preset engine adaptation standard can be used for performing standardized adaptation processing on map engines in various regions, so that user data and service data displayed on the adapted map engines cannot change due to map engine switching, thereby implementing seamless switching of the map engines and ensuring that users can always view the user data and service data displayed on the user terminal 10.
In this embodiment, the preset engine adaptation standard is stored in the user terminal 10, and each map engine needs to be adapted and adjusted based on the preset engine adaptation standard when running in a manner of unifying a mapping entry and an abstract map base class, so that the user terminal 10 can seamlessly switch target map engines to be switched.
In this embodiment, the user terminal 10 implements a switching process of a map engine by restoring and displaying user data and service data, which are originally displayed on a currently running map engine, on an adapted target map engine, and loads and displays service map layer data matched with the target map engine and the target area to the adapted target map engine after restoring and displaying the user data and the service data, so as to display a map corresponding to the target area based on the target map engine.

step S260, if the currently running map engine is the target map engine, the user terminal 10 loads and displays the service map layer data on the currently running map engine, so as to directly display the map corresponding to the target area through the currently running map engine.
In this embodiment, if the currently running map engine of the user terminal 10 matches the optimal map engine information, the user terminal 10 determines that the currently running map engine is the target map engine, at this time, the currently running map engine of the user terminal 10 does not need to perform map engine switching, and the user terminal 10 may directly display the map corresponding to the target area based on the currently running map engine by directly loading and displaying the service map layer data on the currently running map engine by the user terminal 10.
Optionally, please refer to fig. 4, which is a third flowchart illustrating a map switching method according to an embodiment of the present invention.
