Example one

The embodiment provides a processing method of map data, and the embodiment is a processing method for realizing the map data on a client side. Please refer to fig. 1, which is a flowchart illustrating a first embodiment of a method for processing map data according to an embodiment of the present invention, as shown in the figure, the method includes the following steps:

s101, sending M data requests to a server, wherein the M data requests carry different map parameters, so that the server can obtain map data according to the map parameters carried in each data request; m is an integer greater than 1.

S102, receiving the M map data sent by the server.

S103, displaying M views on a client interface, drawing M electronic maps in the M views according to the M map data, and marking the geographic position of the terminal where the client is located on each electronic map.

It should be noted that the terminal involved in the embodiment of the present invention may include, but is not limited to, a Personal Computer (PC), a Personal Digital Assistant (PDA), a wireless handheld device, a tablet computer (tablet computer), a mobile phone, an MP3 player, an MP4 player, and the like.

It should be noted that the execution subjects of S101 to S103 may be processing apparatuses of map data, and the apparatuses may be applications located in the local terminal, or may also be functional units such as a plug-in or a Software Development Kit (SDK) located in the applications located in the local terminal, which is not particularly limited in this embodiment of the present invention.

It should be understood that the application may be an application program (native app) installed on the terminal, or may also be a web page program (webApp) of a browser on the terminal, which is not limited in this embodiment of the present invention.

In the embodiment of the present invention, in order to simultaneously display a plurality of electronic maps on a client interface, M views need to be created in a client in advance, and a display style of each view in the M views needs to be set. Thus, when the client needs to display the electronic map, the client sends M data requests to the server, wherein each data request is used for requesting to acquire one map data. In the embodiment of the invention, M is an integer greater than 1.

In a specific implementation process, each data request carries map parameters, and the map parameters carried in the data requests are different. Map parameters may include, but are not limited to: scale and geographical range. For example, the scale bar may be 1: the geographic range may be the longitude and latitude coordinates of each endpoint over the geographic area 1000.

It can be understood that if the map parameters include a scale and a geographic range, the scale carried in each data request is different and the geographic range carried in each data request is also different.

For example, the view created in the client may be, but is not limited to being, implemented with SurfaceView provided by the Android operating system.

In this embodiment of the present invention, the client may sequentially send the M data requests to the server, or may simultaneously send the M data requests to the server, which is not particularly limited in this embodiment of the present invention.

In a specific implementation process, after receiving M data requests from a client, a server obtains corresponding map data from a database according to map parameters carried in each data request, so that the server can obtain M map data, and further returns the M map data to the client. The map parameters carried in the data requests are different, and the M map data are also different, so that different electronic maps can be drawn on the client.

Further, the client may receive M pieces of map data sent by the server, then the client displays M views created in advance on the client interface, and then, for each piece of map data, the client draws an electronic map on one displayed view according to the map data, so that each view can display one electronic map. It can be understood that, since the map data obtained by the client terminal are different, the electronic map drawn according to the map data is also different.

Furthermore, after the client draws the electronic maps, the geographic position of the terminal where the client is located is marked on each electronic map. In this embodiment, the geographic location of the terminal where the client is located may be obtained by the client in advance from a Global Positioning System (GPS) module of the terminal where the client is located; alternatively, the geographical position of the terminal where the client is located may be acquired from the server by sending a positioning request to the server.

For example, in the present embodiment, if M is equal to 2, the M views include two views, such as a first view and a second view. In creating the two views, the size of each view may be set separately, e.g., the size of the second view may be set smaller than the size of the first view; in addition, the display position of each view can be further set, such as the second view can be set to be displayed on the upper layer of the first view. Furthermore, the transparency of each view may be further set, where since the second view is displayed on the upper layer of the first view, in order not to affect the browsing of the first view, the transparency of the second view may be set to be greater than the transparency of the first view, so that the second view is more transparent than the first view to avoid the occlusion of the first view.

If M is equal to 2, the client may send two data requests and obtain two map data, and may further draw, in the first view, an electronic map corresponding to a larger scale of the two scales, and draw, in the second view, an electronic map corresponding to a smaller scale of the two scales, so that the scale corresponding to the electronic map drawn in the first view is larger than the scale corresponding to the electronic map drawn in the second view.

Alternatively, an electronic map corresponding to a smaller of the two geographic ranges may be rendered in the first view, and an electronic map corresponding to a larger of the two geographic ranges may be rendered in the second view. In this way, the geographic range corresponding to the electronic map drawn in the first view is smaller than the geographic range corresponding to the electronic map drawn in the second view.

In a specific implementation process, because the electronic map drawn on the first view has a larger corresponding scale and a smaller corresponding geographic range, the electronic map drawn on the first view has higher precision and includes partial path information between a starting point and an end point; the partial path information may include a current path of the terminal where the client is located and a next path to be reached. Therefore, through the electronic map drawn on the first view, detailed navigation data such as the current path and the next path can be obtained, and a user can drive according to the detailed navigation data.

Similarly, the electronic map drawn on the second view has a smaller scale and a larger geographic range, so that the electronic map drawn on the second view has a smaller accuracy and contains complete path information between the starting point and the ending point. Therefore, the path summary in the whole process can be obtained through the electronic map drawn on the second view, so that the user can visually know the complete path of the user, and the user can know which part of the complete path is located currently.

In this embodiment, the partial path information between the start point and the terminal is drawn in the first view, the complete path information between the start point and the terminal is drawn in the second view, and the size of the first view is larger than that of the second view, which means that the partial path information is displayed by using the large view, and the complete path information is displayed by using the small view, so that the complete path information and the partial path information can be simultaneously displayed to the user in a form similar to picture-in-picture in the navigation process.

Optionally, in a possible implementation manner of this embodiment, after the M electronic maps are drawn, an operation of a user on the client interface may also be detected; and if the detected operation of the user on the client-side interface is the designated operation, the electronic map is displayed in the M views in an exchange manner.

For example, if it is detected that the user clicks the second view on the client interface, the displayed electronic map may be exchanged among the M views displayed on the client interface, for example, the electronic map displayed in the first view is displayed in the second view, and the electronic map displayed in the second view is displayed in the first view.

Optionally, after the M electronic maps are drawn, a drag operation of a user on the client interface for the second view may be detected, and a display position of the second view is moved on the client interface according to the drag operation.

For example, the second view may be displayed anywhere on the client interface, such as the top left or bottom right, etc.

In the embodiment, a plurality of views can be output to the user in the navigation process, and different electronic maps can be respectively drawn on each view, so that different navigation information can be displayed to the user, and the user can acquire different navigation information at the same time. And moreover, more navigation information is output to the user, the output information amount is improved, the operation cost in the navigation process is reduced, and the operation efficiency is improved.

Example two

The embodiment also provides a processing method of map data, and the embodiment is a processing method for realizing the map data on the server side. Please refer to fig. 2, which is a flowchart illustrating a second embodiment of a method for processing map data according to an embodiment of the present invention, wherein the method includes the following steps:

s201, receiving M data requests sent by a client, wherein the M data requests carry different map parameters, and M is an integer greater than 1.

S202, obtaining map data according to the map parameters carried in each data request.

S203, sending the M map data to the client so that the client can display M views on a client interface, drawing M electronic maps in the M views according to the M map data, and marking the geographic position of the terminal where the client is located on each electronic map.

The execution subjects of S201 to S203 may be processing devices of map data, and the devices may be located in a server.

In this embodiment, in order to simultaneously display a plurality of electronic maps on the client interface, M views need to be created in the client in advance, and a display style of each view in the M views needs to be set. Thus, when the client needs to display the electronic map, the client sends M data requests to the server, wherein each data request is used for requesting to acquire one map data. In the embodiment of the invention, M is an integer greater than 1.

In a specific implementation process, each data request carries map parameters, and the map parameters carried in the data requests are different. Map parameters may include, but are not limited to: scale and geographical range.

In a specific implementation process, after receiving M data requests from a client, a server obtains corresponding map data from a database according to map parameters carried in each data request, so that the server can obtain M map data, and further returns the M map data to the client. The map parameters carried in the data requests are different, and the M pieces of map data are also different, so that the client can draw different electronic maps.

In the embodiment, in the navigation process, the server can provide a plurality of map data to the client according to the data request of the client, so that the client can draw a plurality of electronic maps to the user, different navigation information can be displayed to the user, and the user can acquire different navigation information at the same time. In addition, the client can output more navigation information to the user, so that the output information amount is improved, the operation cost in the navigation process is reduced, and the operation efficiency is improved.
