Below, the terms involved in the embodiments of the present application will be explained to facilitate the reader's understanding.

(1) Tile map

A tile map is a map that combines map data in the form of tiles, and is usually displayed in multiple levels according to a pyramid model. From the top to the bottom of the tile map, the number of tiles continues to increase, and the map information described by each tile is also continuously refined.

Among them, tiles include raster tiles and vector tiles. Raster tiles are used to cut the map into multiple areas, and display the map information in the area through raster pictures. Vector tiles are also called vector slices, and are mainly described in this application as vector slices.

Similar to raster tiles, vector tiles also cut the map into multiple regions. The difference is that vector tiles store the features in each region. Features are used to represent geometric information or attribute information of objects existing in the map. The terminal renders the map information locally through the elements in the vector tiles. Vector tiles are divided into two layers, one is the organization model of the vector tiles within the map extent, and the other is the organization model of the features within each vector tile. The vector slice organization model is used to represent the organization relationship of vector slices at various levels. The organization model of the features within each vector tile is used to represent the feature information within each vector tile.

(2) Points of Interest

Point of interest (POI) refers to the information points with certain value in the map information. For example, POIs can be landmarks, attractions, institutions, transportation facilities, etc. on the map.

(3) Picture frame

Relevant institutions or countries divide and number the map according to a certain scale to generate multiple map sheets. For example, in 1992, the state promulgated the national basic scale topographic map division and numbering standard (GB/T13989-1992), which stipulated the standard map size of each region in the country. Each standard view frame has a specific view frame ID that identifies the view frame.

Under the background of the rapid development of Internet technology and cartography technology, users are more and more dependent on online electronic maps, and the elements of electronic maps have become more abundant. This has also led to an increasing amount of data on electronic maps. To meet user needs, map service providers need to update map data in a timely and frequent manner.

However, in the process of updating the electronic map in the prior art, it is necessary to convert the spatial data into picture data, convert the spatial coordinates into screen coordinates, and express the arrangement order by numbers. Restricted by the renumbering of spatial data, the existing technology cannot accurately identify the changed elements, and then retrieve other element data in the vector slice where the changed elements are located to generate new vector slices. Therefore, when updating the electronic map It is necessary to replace the vector tiles in the map before the update as a whole, which results in that when there are too many vector data in the map before the update, it takes a lot of time to update the map data. During this period, the user cannot obtain the required map. services, thereby affecting the user experience.

In order to solve the problem in the prior art that map data cannot be updated timely and frequently, the present application provides a vector map update method.

As shown in FIG. 3, FIG. 3 is a flowchart of a method for updating a vector map provided by an embodiment of the present application, and the method includes the following steps:

S301. The vector map updating apparatus acquires vector update data.

Wherein, the vector update data includes vector data to be updated of at least one element in the vector map.

In a possible implementation manner, the vector data to be updated includes at least one of the following: POI data, water system surface data, building data, cell data, and road surface data. Types of features include point features, line features, polygon features, and composite features. A composite feature is a combination of multiple types of features.

Exemplarily, the POI data includes administrative division points, scenic spots, and transportation stops. The water system surface data includes water information, vegetation information, ferries, and bridges. Building data includes building plans, building heights, building categories. The cell data includes cell plane information, residential area information, and residential area subsidiary information. Road surface data includes road coverage area and road name.

In a possible implementation manner, the vector data to be updated includes at least one of vector addition data, vector deletion data, and vector modification data.

Among them, the vector addition data is used to indicate the vector data of the elements to be added. The vector deletion data is used for vector data indicating elements to be deleted. The vector modification data is used to indicate the modified vector data of the preset element.

Exemplarily, the vector addition data includes elements to be added and addition flags. Vector deletion data includes features to be deleted and delete markers. Vector modification data includes elements to be modified and modification markers.

Exemplarily, the vector update data may be a shp format file.

S302. The vector map updating apparatus determines a first vector slice according to the vector update data.

The first vector slice is a vector slice generated according to vector data of elements in the first area. The elements in the first area include at least one element in the vector update data.

It should be noted that the first vector slice is a vector slice in which elements that need to be updated exist in the corresponding first area. That is to say, according to the vector update data, the vector map update device in the present application can determine the vector slices in the vector map that need to be updated, and then update the map with the vector slices as the granularity.

In a possible implementation manner, the vector map updating apparatus may acquire vector data of each element in the map data before updating, and determine the position information of each element. The vector map updating apparatus determines that the vector data of the elements located in the first area among the elements are the elements included in the first vector tile before the map update.

Exemplarily, the map data before updating may be stored in the map data master database in the vector map updating device, and the vector map updating device obtains the map data by calling the vector data in the map data master database.

S303. The vector map updating apparatus updates the elements in the first area according to the vector update data, and generates a second vector slice according to the updated elements in the first area.

It should be noted that the second vector slice is a vector slice including vector data of updated elements in the corresponding first area. After the vector map updating device determines the first vector slice, it can update the elements in the first area corresponding to the first vector slice, and then obtain the updated second vector slice.

Exemplarily, the generated second vector slice is a pbf format file. The vector map updating apparatus may store the generated plurality of vector tiles in a vector tile updating database. The vector map updating apparatus can call the vector tiles in the vector tile updating database to display the updated map picture. At the same time, since the vector map updating device does not directly modify the existing map data, the vector map updating device can also roll back the map data to the version before the update at any time according to the update requirement.

In a possible implementation manner, before generating the second vector slice, the apparatus for updating the vector map may further check the elements in the updated first area.

Exemplarily, the apparatus for updating the vector map may remove elements corresponding to repeated and wrong vector data among the elements in the updated first area. The vector map updating apparatus may also generate a verification report according to the verification process. The verification report is used to record the verification operations during the verification process.

S304. The vector map updating device updates the vector map according to the second vector slice.

In a possible implementation manner, the vector map update device may send the second vector tile to the map server, so that the map server replaces the vector tile corresponding to the second vector tile in the current map data with the second vector tile, thereby completing the vector map. Map update.

Exemplarily, the vector map update apparatus may generate a map update data package according to the second vector tile, and send the map update data in the form of a map update data package. Wherein, the map update data package includes the second vector slice and the update content description. In this way, the vector map update device can further compress the map update data and improve the map update efficiency. At the same time, the map server can also determine the update content according to the map update data package.

It should be noted that, after the map server receives the second vector tile sent by the vector map update device, it can also compare the received map picture corresponding to the second vector tile with the map picture of the map data stored in the map server, and judge that the received Whether the second vector slice of satisfies the update requirement. If the update requirements are met, the map server replaces the vector tiles in the stored map data with the received corresponding second vector tiles; if the update requirements are not met, the map server can delete the received second vector tiles and notify the vector map update Device map update failed.

In another possible implementation manner, the map server may be coupled to the vector map update device, and the vector map update device replaces the vector tile corresponding to the second vector tile in the current map data with the second vector tile, thereby completing the vector map update .

The above solution at least brings the following beneficial effects: the vector map update device in the present application obtains the vector update data to be updated, and determines according to the vector update data that there is a first vector slice of the element that needs to be updated, and then updates the first vector slice according to the vector update data. For a plurality of vector elements in the first area corresponding to the vector slice, a second vector slice including the vector data of the updated elements in the first area is generated. In this way, the apparatus for updating the vector map can update the map according to the second vector tile based on the granularity of the vector tile. Compared with the technical solution in the prior art that when the map data needs to be updated, the server needs to perform an overall replacement of the map data package, the present application only needs to replace the first vector slice in the current map data with the second vector slice. The update of map data greatly improves the map update speed. At the same time, based on the granularity of vector slices, the present application can dynamically update the vector map online. During the map update process, the user can use the map service normally by invoking the unchanged vector slices, thereby avoiding bad user experience. influences.

In a possible implementation manner, the vector data to be updated of at least one element includes at least one of first vector addition data, first vector deletion data, and vector modification data.

The first vector addition data is used to indicate vector data of elements to be added. The first vector deletion data is used for vector data indicating elements to be deleted. The vector modification data is used to indicate the modified vector data of the preset element.

Therefore, the vector map updating device updates the elements in the first area according to the vector update data, and generates the second vector tile according to the updated elements in the first area. There are three cases as follows. Case 1: The vector data to be updated of at least one element includes the first vector addition data. Case 2: The vector data to be updated of at least one element includes the first vector deletion data. Case 3: The vector data to be updated of at least one element includes vector modification data.

In case 1: the vector map updating means adds the vector data of the element to be added in the first area. The vector map updating device generates a second vector tile based on the elements in the first area after adding the elements.

Exemplarily, the first area includes element A, element B, and element C. The first vector addition data includes element D. The vector map updating apparatus adds element D in the first area, and the obtained elements in the first area after adding the element include element A, element B, element C, and element D.

In case 2: the vector map updating means deletes the vector data of the same element as the element to be deleted in the first area. The vector map updating device generates a second vector tile based on the elements in the first area after the elements have been deleted.

Optionally, the vector map updating apparatus determines the coding identifier of the element to be deleted according to the first vector deletion data, so as to delete the corresponding element in the first area according to the coding identifier.

Exemplarily, the first area includes element A, element B, and element C. The first vector deletion data includes element B. The vector map updating apparatus deletes the element B existing in the first area, and the obtained elements in the first area after the element is deleted include the element A and the element C.

In case 3: the vector map updating means divides the vector modification data into the second vector deletion data and the second vector addition data. The vector map updating device deletes the vector data of the preset elements in the first area according to the second vector deletion data, and adds the modified vector data of the preset elements in the first area. The vector map updating means generates a second vector tile according to the added elements in the first area.

Wherein, the second vector deletion data is used to instruct to delete the vector data of the preset element, and the second vector addition data is used to instruct to add the modified vector data of the preset element.

Exemplarily, the first area includes element A, element B, and element C. The vector modification data includes element C1 for modifying element C in the first area to element C1. Therefore, the vector map updating means divides the vector modification data into the second vector deletion data and the second vector addition data. The second vector deletion data includes element C, and the second vector addition data includes element C1.

The vector map updating apparatus deletes the element C in the first area, and the deleted elements in the first area include the element A and the element B.

The vector map updating apparatus adds the element C1 to the first area, and the added elements in the first area include the element A, the element B, and the element C1.

The vector map updating apparatus generates a second vector tile based on the element A, the element B, and the element C1.

Hereinafter, the process of determining the first vector slice by the vector map updating apparatus will be described in detail with reference to the above step S302.

As a possible embodiment of the present application, with reference to FIG. 3 , as shown in FIG. 4 , the above step S302 can be specifically implemented by the following steps S401-S404:

S401. The vector map updating apparatus determines a first picture frame corresponding to the vector update data according to the frame identifier in the vector data to be updated.

Wherein, the vector data includes image frame identifiers.

It should be noted that the vector data in this application includes a frame identifier, and according to the frame identifier corresponding to the vector data of each element, the vector map updating apparatus can determine the first frame corresponding to the vector update data. That is to say, the vector map updating apparatus can determine the frame where each element is located according to the frame identifier.

In a possible implementation manner, the vector map update apparatus may encode at least one element included in the vector update data according to a preset rule.

Exemplarily, the preset rules may be a map frame identification, an administrative area number, and a feature type. For multiple features with the same frame ID, administrative area number, and feature type, the codes can be accumulated sequentially. For example, the map frame ID is 01, the administrative area number is 02, and the element type is the vector A and vector B of the point element (corresponding to the number 03). In this way, at least one element included in the vector update data has a unique coded identifier. The vector map updating apparatus can determine each element according to the coded identification.

S402. The vector map update device determines at least one third vector slice corresponding to the first image frame and a second area corresponding to each third vector slice according to the first mapping relationship and the first image frame corresponding to the vector update data.

The first mapping relationship is used to represent the mapping relationship between the map frame and the vector slice. The picture frame includes the first picture frame, and the vector slice includes the third vector slice.

It should be noted that there is a first mapping relationship between the picture frame and the vector slice in this application. According to the first mapping relationship, the vector map updating apparatus can determine the vector slice corresponding to each picture frame, and can also determine the corresponding picture frame according to each vector slice.

Specifically, since a vector slice has multiple levels, the higher the level of the vector slice, the larger the area covered by the vector slice, and the lower the level of the vector slice, the smaller the area covered by the vector slice. As shown in FIG. 5 , the correspondence between the map frame and the vector slice includes the following four cases.

Case 1. The coverage area of the vector tile is within the coverage area of the map frame.

In case 2, the coverage area of the map frame is within the coverage area of the vector slice.

Case 3. The coverage area of the map frame partially overlaps the coverage area of the vector slice.

Case 4. The coverage area of the map frame does not coincide with the coverage area of the vector slice.

The first mapping relationship between the map frame and the vector slice in this application belongs to the above-mentioned cases 1 to 3, that is to say, if there is an overlapping area between the coverage area of the map frame and the coverage area of the vector slice, it is determined that the map frame and the coverage area of the vector slice overlap. The vector slice is corresponding.

Exemplarily, the first frame includes frame 1 and frame 2. According to the first mapping relationship, the apparatus for updating the vector map can determine that the vector slices corresponding to the picture frame 1 include slice 1, slice 2 and slice 3, and the vector slices corresponding to the picture frame 2 include slice 4 and slice 5. Therefore, the at least one third vector slice corresponding to the first picture frame is slice 1 , slice 2 , slice 3 , slice 4 , and slice 5 .

S403. The vector map updating apparatus determines an area including at least one element in the second area as the first area.

It should be noted that the third vector slice determined by the vector map updating apparatus in this application is the vector slice corresponding to the first picture frame, so the second area corresponding to the third vector slice can cover the area of the first picture frame.

However, there may be at least one vector slice in the third vector slice that does not include elements in the vector update data, and the at least one vector slice does not need to be updated. Therefore, the vector map updating apparatus also needs to remove the area in the second area that does not include the elements of the vector update data, so that the first area and the elements included in the first area can be determined from the second area.

Exemplarily, the second area includes area 1, area 2, area 3, and area 4. Area 1 corresponds to vector slice 1, area 2 corresponds to vector slice 2, area 3 corresponds to vector slice 3, and area 4 corresponds to vector slice 4. The area 1 includes the element 1 in the vector update data, the area 2 includes the element 2 in the vector update data, and the area 3 includes the element 3 in the vector update data. Therefore, the vector map updating apparatus determines the area 1, the area 2 and the area 4 in the second area as the first area.

S404. The vector map updating apparatus determines that the third vector slice corresponding to the first area is the first vector slice.

With reference to the above example, the vector map updating apparatus determines the vector slice 1 , the vector slice 2 and the vector slice 4 corresponding to the area 1 , the area 2 and the area 4 as the first vector slice.

Through the above technical solution, the vector map update device in the present application can determine the first map frame corresponding to the vector update data according to the frame identifier in the vector data to be updated of at least one element in the vector update data, and according to the first mapping relationship And the first picture frame determines at least one third vector slice corresponding to the first picture frame. In this way, the vector map updating apparatus can reduce the range of vector slices to be updated from all vector slices in the map data to at least one third vector slice corresponding to the first picture frame, reducing the calculation amount of the vector map updating apparatus. Further, the vector map update device can determine the vector slice corresponding to the second area including at least one element of the vector update data in the third vector slice, thereby excluding the vector slices that do not need to be updated in the third vector slice, greatly reducing the number of vector slices. The vector tiles required for the update have been increased, and the map update speed has been improved.

As a possible embodiment of the present application, with reference to FIG. 3 or FIG. 4, as shown in FIG. 6, after the above S404, the method may further include the following steps S601-S603:

S601. The vector map updating apparatus determines a second map frame corresponding to the first vector slice according to the first mapping relationship and the first vector slice.

Wherein, the picture frame further includes a second picture frame.

It should be noted that, after the first vector slice is determined, the vector map updating apparatus may obtain the second image frame corresponding to the first vector slice according to the first mapping relationship. The region of the second picture frame can cover the first region corresponding to the first vector slice.

S602. The vector map updating apparatus acquires the vector data of the elements in the second picture frame, and determines the position information of the elements in the second picture frame.

In a possible implementation manner, the apparatus for updating the vector map may determine, according to the frame ID of the second frame, the vector data of the elements having the corresponding frame ID in the map data before updating.

Exemplarily, the map data before updating may be stored in the map data master database in the vector map updating device, and the vector map updating device obtains the map data before updating by calling the vector data in the map data master database.

It should be noted that the vector data includes the position information corresponding to the element, so the vector map updating apparatus can determine the position information of the element according to the vector data of the element.

S603. The vector map updating apparatus determines that the vector data of the elements located in the first area and in the second picture frame is the vector data of the elements in the first area.

It should be noted that after determining the location information of the elements in the second frame, the vector map updating apparatus can determine the elements in the second frame within the coverage area according to the coverage area corresponding to the first area. Wherein, since the elements in the second map frame are elements in the map data before updating, the vector map updating apparatus can determine the elements in the first area corresponding to the first vector slice.

The above solution at least brings the following beneficial effects: the vector map update device in the present application can determine the second map frame corresponding to the first vector slice according to the first mapping relationship and the first vector slice, and obtain the vector of the elements in the second map frame data. Since the area of the second map frame can cover the first area corresponding to the first vector slice, the elements in the second map frame include elements in the first area corresponding to the first vector slice. In this way, the vector map updating apparatus can determine the elements in the second frame in the first area, that is, the elements in the first area corresponding to the first vector slice, according to the position information of the elements in the second frame. Based on the above technical solution, the vector map update apparatus can determine the vector data of the elements before the update in the vector slice to be updated, so as to facilitate the subsequent update of the elements in the first area to generate the updated second vector slice.

Hereinafter, the process of verifying the generated second vector slice by the vector map updating apparatus will be specifically introduced.

As a possible embodiment of the present application, with reference to any one of FIGS. 3-4 and 6, as shown in FIG. 7, the method may further include the following steps S701-S704:

S701. The vector map updating apparatus renders the first vector slice, determines the map image before updating, renders the second vector slice, and determines the updated map image.

Exemplarily, the apparatus for updating a vector map may render a corresponding map picture according to the vector slice before updating and the vector slice after updating through the map rendering engine, so as to facilitate subsequent comparison and verification.

For the specific solution of rendering the map picture by the vector map update device, reference may be made to the prior art, which is not limited in this application.

S702 , the vector map updating apparatus displays the map screen before updating and the map screen after updating.

It should be noted that, by displaying the map screen before update and the map screen after update, relevant staff can determine whether the updated map data meets the current update requirements.

In a possible implementation manner, the vector map updating device can also acquire and display satellite image data, so that the relevant staff can further judge whether there is information error in the updated map data.

S703. The vector map updating apparatus receives the first instruction.

Wherein, the first indication is used to instruct to confirm the map update, or the first indication is used to instruct to delete the second vector slice.

S704. The vector map updating apparatus performs vector tile processing according to the first instruction.

In a possible implementation manner, if the first indication is used to indicate confirmation of map update, the vector map update device updates the vector map according to the second vector slice.

In another possible implementation manner, if the first indication is used to indicate deletion of the second vector slice, the second vector slice is deleted.

Exemplarily, after the second vector tile is deleted, the vector map update apparatus may re-acquire vector update data to perform map update.

Through the above technical solution, the vector map updating device in the present application can render and display the map picture before updating and the map picture after updating according to the first vector tile and the second vector tile before updating the vector map according to the second vector tile, The corresponding vector tile processing operation is performed through the received first instruction, thereby avoiding the user's use experience from being affected after the map update because the map update cannot meet the update requirement. Because the vector map update device in the present application first compares the map data, and then updates the vector map according to the second vector slice, that is, the map update data verification operation is carried out before the map update, which avoids the need for new updates after the update if the update requirements are not met.
