In the existing electronic map display technology, real geographic information is converted into vector data through a server, the vector data is rendered by a client, the rendered vector data is obtained, and the rendered vector data is displayed in an electronic map.

The defects of the existing implementation schemes are the results of the inventor after practice and careful study, so the discovery process of the above problems and the solution proposed by the present disclosure to the above problems in the following should be the contribution of the inventor to the present disclosure in the process of the present disclosure.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.

It should be noted that specific terms mentioned in the embodiments of the present disclosure include:

vector tile: the vector tile data exists in a vector form, is organized and defined through different description files, and is analyzed and drawn in real time at a client. Namely, after the client acquires data such as vector tiles, map labeling fonts, icons, style files and the like through the distributed network, rendering and outputting the map at the client. Compared with the traditional raster tiles, the vector tiles have the advantages of small volume, high compression, small occupied storage space, small data transmission volume and low map updating cost.

In order to facilitate understanding of the embodiment, a detailed description is first given of a map editing method disclosed in the embodiment of the present disclosure, an execution subject of the map editing method provided in the embodiment of the present disclosure is generally a computer device with certain computing capability, and in some possible implementations, the map editing method may be implemented by a processor calling a computer readable instruction stored in a memory.

The following describes a map editing method provided by the embodiment of the present disclosure by taking an execution subject as a client.

As shown in fig. 1, a flowchart of a map editing method applied to a client according to an embodiment of the present disclosure may include the following steps:

s101: first editing information is generated in response to an editing operation on a target image area on a displayed electronic map.

Here, the client may be any mobile terminal having a capability of loading an electronic map, for example, the client may be a user mobile phone, a tablet computer, a Personal Digital Assistant (PDA), a handheld device, a computing device, or the like for displaying the electronic map in a navigation scene; the electronic map display device can also be an on-board device (such as an on-board display screen device) for displaying the electronic map in a driving scene, and the like.

The electronic map can be a map generated by adopting a vector tile technology, and the electronic map can comprise at least one vector tile, wherein one vector tile comprises at least one piece of vector data, and each piece of vector data is generated according to real geospatial information.

The first editing information is information for editing the electronic map.

The vector tiles correspond to target image areas in the electronic map, at least one target image area may be included in the electronic map, different target image areas do not overlap in the electronic map, each target image area corresponds to one presentation image in the electronic map, and there may be a difference in image shape of the different presentation images, for example, the image shape of the presentation image corresponding to target image area Q1 may be a rectangle, and the image shape of the presentation image corresponding to target image area Q2 may be an irregular polygon.

The editing operation may be performed at a client displaying the electronic map by a user who has an editing requirement on a vector tile in the electronic map, and since the vector tile corresponds to a target image area in the electronic map, the editing requirement on the vector tile is the editing requirement on the target image area for the user.

In specific implementation, on the premise that the client is loaded with the vector tile service, an electronic map can be obtained and displayed on the client based on rendering of vector tiles acquired from the server, wherein the electronic map can include at least one target image area.

Further, the user may select a target image area to be edited and perform an editing operation on the target image area, for example, change the position of the target image area, change the area range of the target image area, or the like. Then, the client may receive an editing operation performed by a user, and generate first editing information according to the target image area to be edited and the edited target image area in response to the editing operation. Specifically, the client may generate the first editing information according to an area graph corresponding to the edited target image area and position information of each target vector tile corresponding to the area graph. Alternatively, the first editing information may be generated directly from the position information of the region figure corresponding to the edited target image region.

S102: and sending the first editing information to the server.

Here, the server is a generator corresponding to the electronic map, and may be in communication connection with each client using the electronic map function, so as to update the electronic map displayed by the client.

The initial graphic element information is editable information corresponding to the target image area, and specifically, the editable information may include editable area graphics capable of representing the area range size of the target image area, editable element points capable of representing the area range size of the target image area, and the like, where the editable element points may be part of important key points corresponding to the editable area graphics, taking the editable area graphics as a rectangle as an example, the editable element points may be four vertices corresponding to the rectangle and midpoints of sides of the rectangle, and the editable element points are editable element points. The initial graphic element information can represent the target image area and can be used for editing the target image area, and when the specific implementation is carried out, a user can edit the target image area by adjusting the initial graphic element information corresponding to the target image area. Taking the editable area graph corresponding to the initial graph element information as a rectangle and the editable element points as four vertexes corresponding to the rectangle and the middle points of each side of the rectangle as examples, the adjustment of the initial graph element information may be a position moving operation of each editable element point by the user and a moving operation of each side of the rectangle.

The initial graphic element information corresponding to the target image area can be generated by the server and sent to the client, and the client can store the received initial graphic element information, and generate and display the target image area corresponding to the electronic map by using the initial graphic element information. After the server generates the initial graphic element information, the server may store the initial graphic element information in a database corresponding to the server. That is, the initial graphic element information corresponding to each target image area in the electronic map displayed by the client is stored in both the server and the client.

The target graphic element information is graphic element information corresponding to the edited target image area and is newly generated by the server.

In this step, after generating the first editing information, the client may send the first editing information to the server through the communication network, and further, after receiving the first editing information, the server may generate the target graphic element information corresponding to the target image area according to the first editing information.

Specifically, after receiving the first editing information, the server may determine each target vector tile to be operated according to the position information of each vector tile corresponding to the edited target image area in the first editing information, and may then obtain initial graphic element information and vector data corresponding to each target vector tile to be operated, which are stored in the database.

Alternatively, when the first editing information includes only the position information of the area graphic corresponding to the edited target image area, an overlap vector tile having position information overlapping the position information of the area graphic may be determined based on the position information of the area graphic and the position information of each vector tile generated corresponding to the electronic map, and the overlap vector tile may be set as the determined target vector tile.

Then, the server may adjust the initial graphic element information corresponding to each target vector tile based on the vector data of each target vector tile and the area graphics, respectively, to obtain the target graphic element information corresponding to each target vector tile, that is, to generate a new vector tile corresponding to the edited target image area. Here, the generated new vector tile is a file in a preset format, where the preset format may be a file format of a Mapbox vector tile standard.

After the server generates the target graphic element information, the server may delete the initial image element information corresponding to each of the stored target vector tiles and store the newly generated target graphic element information, thereby updating the data stored in the server.

S103: and receiving target graphic element information fed back by the server end in response to the first editing information, and updating a first display image corresponding to the target image area based on the target graphic element information to obtain the edited electronic map.

Here, each vector tile may correspond to one presentation image, and the first presentation image may include a presentation image corresponding to each of the target vector tiles corresponding to the edited target image area.

In specific implementation, the server may send the generated target graphic element information to the client through the communication network, so that the client may render a new vector tile corresponding to the target graphic element information after receiving the target graphic element information fed back by the server, obtain a rendered new display image, update the first display image corresponding to the target image area by using the obtained new display image, and obtain an edited and updated electronic map.

Or, the client may also initiate a request for obtaining target graphic element information corresponding to each target vector tile to the server according to the position information of each target vector tile corresponding to the edited target image area, and then the server may send the target graphic element information to the client in response to the request, thereby completing updating of the first display image corresponding to the target image area.

Therefore, different target image areas correspond to vector data with different data volumes, the plurality of target image areas correspond to all vector data of the electronic map, and based on the editing operation on the target image areas, the editing of partial vector data corresponding to the target image areas in all the vector data according to the editing requirements can be realized, so that the data volume needing to be processed is reduced, and the editing efficiency is improved. Meanwhile, the generated first editing information is sent to the server side so that the server side can update the initial graphic element information corresponding to the target image area, a user can edit the vector data corresponding to the electronic map displayed in the client side only by executing operation on the client side, and convenience of data processing is improved.

In an embodiment, the target image area includes at least one vector tile corresponding to the electronic map, that is, one target image area may include at least one vector tile, so that, based on the editing operation on the target image area, it may be possible to implement synchronous editing on multiple vector tiles, for example, in a case that one edited vector tile overlaps with another vector tile, the server may adaptively edit the other overlapped vector tile, so that editing on one vector tile may be synchronized to editing on the other overlapped vector tile, thereby improving editing efficiency. As shown in fig. 2, a target image area provided for the embodiment of the present disclosure includes a schematic diagram of a plurality of vector tiles, where the target image area a includes a plurality of vector tiles, specifically, a vector tile V1, a vector tile V2, and a vector tile V3.

In one embodiment, the editing operation includes a first sub-operation and a second sub-operation.

Here, the first sub-operation is an operation on a target image area in the electronic map, and as is clear from the above embodiment, the target image area corresponds to a presentation image having a certain image shape, so in concrete implementation, the first sub-operation may be an operation in which the user clicks the presentation image corresponding to the target image area.

The second sub-operation is an operation for the initial graphic element information corresponding to the target image area.

For S101, the following steps may be performed:

step one, responding to a first sub-operation of a target image area on a displayed electronic map, and acquiring initial graphic element information corresponding to the target image area from a client.

Here, the client stores therein initial graphic element information corresponding to each target image area in the electronic map. The initial graphic element information comprises all element points which surround a target image area, and the position and the number of the element points corresponding to different target image areas are different.

The vector tiles corresponding to the target image areas in the electronic map can be displayed at different image zoom levels, and in each image zoom level, the number and the positions of the vector tiles in the electronic map are fixed, but the data size of the initial graphic element information corresponding to each vector tile is in an association relationship with the image zoom level. Specifically, for the same vector tile, the lower the image scaling level is, the less the data amount of the initial graphic element information corresponding to the vector tile in the electronic map is, the less the number of the essential points in the initial graphic element information corresponding to the vector tile is, and conversely, the more the data amount corresponding to the vector tile is, the more the essential points in the initial graphic element information corresponding to the vector tile is.

In specific implementation, initial graphic element information of all vector tiles in the electronic map, which corresponds to each image zooming level, is stored in both the client and the server.

For this step, the client may determine, in response to a click operation of a user on a display image corresponding to a target image area on the displayed electronic map, a vector tile corresponding to the target image area, and an image zoom level corresponding to the electronic map when the click operation is performed. Then, the client may obtain initial graphic element information corresponding to the image zoom level from the locally stored initial graphic element information corresponding to the respective image zoom level of the vector tile.

And secondly, displaying the initial graphic element information through the client, and determining first position information of each element point in at least part of the element points based on a second sub-operation on the element points corresponding to the initial graphic element information.

In specific implementation, after the initial image information is acquired, the initial graphic element information may be displayed at the client, that is, each editable element point corresponding to the target image area is displayed to the user. As shown in fig. 3, a schematic diagram of a target image area and initial graphic element information is provided in an embodiment of the present disclosure, where the initial graphic element information corresponds to an element point a, an element point b, an element point c, an element point d, an element point e, an element point f, an element point g, an element point h, and an element point i.

Furthermore, the user may perform a second sub-operation on at least some of the elements corresponding to the presented initial graphic element information to implement editing of the target image area.

In one embodiment, the second sub-operation may include a factor point deleting operation and/or a factor point moving operation. Specifically, the user may perform at least one of the two second sub-operations on at least part of the displayed element points, thereby implementing editing of the area range of the target image area corresponding to the initial graphic element information.

After the user performs the second sub-operation, the client may determine first location information corresponding to each of at least some of the element points corresponding to the operated initial graphic element information in the electronic map, where the first location information may be map coordinates of each pixel point.

And thirdly, generating first editing information based on the determined first position information.

Here, based on the determined first location information and the location information corresponding to each vector tile stored by the client, each target vector tile having location information overlapping with the first location information is determined, and then, identification information of each target vector tile may be determined, specifically, the identification information may be a rank value of each target vector tile in the electronic map.

Further, first editing information may be generated according to the identification information and the first location information of each target vector tile. Here, the first editing information may be editing information corresponding to each image scaling level, and since the position information and the identification information of the vector tile corresponding to each image scaling level are the same, the server may determine the identification information and the position information of each target vector tile corresponding to the edited target image region according to the first editing information after acquiring the first editing information, and thus may determine the target vector tile corresponding to the identification information and the position information in each image scaling level from the stored vector tiles according to the identification information and the position information, and delete the target vector tile corresponding to each image scaling level and the initial graphic element information corresponding thereto stored by the server after generating the target graphic element information corresponding to the target vector tile of each image scaling level, and updating the data corresponding to the server.

In an embodiment, after receiving the target graphic element information fed back by the server in response to the first editing information, the client may further determine an image area to be adjusted corresponding to the target image area based on the determined first position information of the adjusted element point. Here, the image area to be adjusted is an image area to which each target vector tile corresponding to the adjusted target image area belongs.

Specifically, a target vector tile corresponding to each first position information may be determined according to the adjusted first position information of each element point, and then, an image area corresponding to each target vector tile may be used as an image area to be adjusted.

And determining the target vector tiles corresponding to the image scaling levels according to the identification information and the position information of the target vector tiles corresponding to the image area to be adjusted. The initial graphic element information of the target vector tiles stored at the client for which the image area to be adjusted corresponds to the respective image zoom level may then be deleted. And storing the obtained target graphic element information in the client, wherein the target graphic element information fed back by the server is the target graphic element information of the target vector tiles corresponding to the image scaling levels newly generated by the server based on the first editing information.

In one embodiment, before responding to an editing operation on a target image area on a displayed electronic map, a map editing request initiated by a user is required to be responded, for example, a map editing page corresponding to the electronic map is displayed through a client in response to an operation that the user clicks an editing component on the client. The map editing page comprises at least one target image area.

For example, a user may click a map editing component at a preset position of an electronic map page, and then the client may determine that the user has initiated a map editing request in response to a click operation of the user, and then obtain and display the map editing page and a target image area corresponding to the electronic map to the user in response to the map editing request.

In the process of obtaining the target image area corresponding to the electronic map, all the target image areas corresponding to the electronic map may be obtained, or the target image areas corresponding to the currently displayed vector tiles and the currently displayed image scaling level may be obtained based on the currently displayed image scaling level of the electronic map and the currently displayed vector tiles of the client, that is, the number of the obtained target image areas is consistent with the number of the currently displayed vector tiles, and the size of each target image area corresponds to the image scaling level.

In one embodiment, after a map editing page corresponding to the electronic map is displayed through the client, the vector tiles displayed in the electronic map can be updated according to the following steps:

p1: and determining an image area to be added input on the map editing page.

Here, the image area to be added includes a plurality of element points to be added specified by the user.

After the map editing page is displayed on the client, the user can input an image area to be added at any position in the map editing page, wherein the image area to be added and a target image area displayed on the map editing page can be overlapped or independent.

In specific implementation, a user can draw a target graph in any shape in a map editing page, and then, a client can take an area range corresponding to the target graph as an image area to be added.

P2: and generating second editing information based on second position information corresponding to each element point to be added in the image area to be added.

In this step, after the image area to be added is determined, second position information of each element point to be added in the image area to be added may be obtained, and then, second editing information may be generated according to the second position information and the target graph corresponding to the image area to be added.

P3: and sending the second editing information to the server.

In this step, the client may send the generated second editing information to the server through the communication network, and after receiving the second editing information, the server may determine, according to each piece of second location information corresponding to the second editing information and location information of each generated vector tile, a vector tile to be edited, whose location information corresponds to the second location information, from each generated vector tile. And the tiles to be edited comprise vector tiles of which the image areas to be added correspond to the image scaling grades.

Furthermore, the to-be-added graphic element information of the new vector tile corresponding to each image scaling level can be respectively generated according to the vector data of the to-be-edited vector tile corresponding to each image scaling level and the target graphic corresponding to the second editing information.

Then, the server side can feed back the information of the graphic elements to be added corresponding to each generated image scaling level to the client side.

And after generating the to-be-added graphic element information of the new vector tile corresponding to each image scaling level, the server may delete the initial image element information corresponding to the to-be-edited vector tile corresponding to each image scaling level stored in the local database, and store the to-be-added graphic element information of the new vector tile. Specifically, the vector tiles to be edited can be directly deleted, and new vector tiles can be stored.

P4: and the receiving server responds to the graphic element information to be added fed back by the second editing information, and generates and displays a second display image corresponding to the image area to be added based on the graphic element information to be added.

The graphic element information to be added is the graphic element information of the server side, which is generated based on the second editing information, of the image area to be added and corresponds to each image scaling grade.

In specific implementation, for each image scaling level, after receiving the graphic element information to be added, which is fed back by the server in response to the second editing information, the client may generate the second display image corresponding to the image scaling level according to the received graphic element information to be added and the vector data corresponding to the image scaling level.

Then, the client may display the second display image corresponding to the image zoom level in the electronic map in the client according to the image zoom level corresponding to the electronic map when the second editing information is generated. Specifically, the second display image corresponding to the image zoom level may be used to replace the display image corresponding to the vector tile to be edited, which is displayed in the client, and the second display image is displayed to the user, so that the electronic map displayed in the client is updated.

In an embodiment, after receiving the to-be-added graphic element information fed back by the server in response to the second editing information, the client may determine, according to second location information of each to-be-added element point corresponding to the to-be-added graphic element information and location information of a generated vector tile corresponding to each image scaling level stored locally, a to-be-edited vector tile corresponding to each image scaling level respectively, and then, take initial graphic element information of the to-be-edited vector tile corresponding to each image scaling level as the to-be-deleted element information corresponding to the image scaling level.

Furthermore, the client can delete the element information to be deleted corresponding to each image scaling level, that is, delete the vector tile to be edited corresponding to each image scaling level, and store the obtained graphic element information to be added, thereby completing the update of the data information stored by the client.

Or, the server side can send the identification information of each vector tile to be edited, which is determined by the server side, while sending the information of the graphic elements to be added, and the client side can directly delete the generated vector tiles which are stored locally and matched with the identification information after receiving the information and generating the information of the graphic elements to be added, and store the information of the graphic elements to be added, thereby completing data updating. Therefore, the client omits the step of determining the vector tiles to be edited according to the second position information, and the data updating speed is improved.
