Description

Technical Field

[0001] This disclosure relates to the field of computer technology, and in particular to a vector data processing method, apparatus, electronic device, and storage medium. Background Technology

[0002] Vector data refers to data represented using mathematical vectors. Common vector data types include points, lines, and surfaces, and are widely used in spatial analysis and geometric operations. With the development of computer science, the volume of vector data is constantly expanding, thus necessitating the querying, transmission, and processing of large amounts of vector data.

[0003] In related technologies, spatial index structures can be used to manage vector data to accelerate spatial queries and filtering. By establishing spatial indexes, the system can quickly identify data blocks that intersect or overlap with the current view and load the relevant data, thereby improving the processing performance of vector data.

[0004] However, when processing vector data of several megabytes, tens of megabytes, or even hundreds of megabytes, related technologies still lead to issues such as high latency, memory pressure, computational complexity, and data transmission problems. These shortcomings can result in longer request response times, degraded system performance, and data transmission instability, and may even cause interface timeouts, leading to service unavailability.

[0040] The terminal device 101 can receive query requests sent by users and obtain the map image corresponding to the query request based on the server 103. Furthermore, the terminal device 101 can display the map image.

[0041] Then, when the user edits the map image, the terminal device 101 can obtain the vector data corresponding to the map image.

[0050] Those skilled in the art will know that Figure 1 The number of terminal devices, networks, and servers shown is merely illustrative; any number of terminal devices, networks, and servers can be included depending on actual needs. This disclosure does not limit the scope of the embodiments.

[0051] Under the above system architecture, this disclosure provides a vector data processing method that can be executed by any electronic device with computing capabilities.

[0052] In some embodiments, the vector data processing method provided in this disclosure can be executed by a terminal device of the system architecture described above; in other embodiments, the vector data processing method provided in this disclosure can be executed by a server in the system architecture described above; in still other embodiments, the vector data processing method provided in this disclosure can be implemented by the terminal device and the server in the system architecture described above through interaction.

[0053] Figure 2 A flowchart of a vector data processing method according to an embodiment of this disclosure is shown, such as... Figure 2 As shown, the vector data processing method provided in this embodiment includes the following steps S202 to S208.

[0054] S202, Display the corresponding map image based on the user's query request.

[0055] In an exemplary embodiment, the query request can be used to request a map image of a certain area. For example, the map image may include at least one primary fence, and each primary fence may include at least one secondary fence, and so on, the map image may consist of multiple levels of fences.

[0056] In some exemplary embodiments, map images are used to describe the region corresponding to the target fence. This disclosure does not limit the level of the target fence. In one possible implementation, the fence level may include levels one to four, wherein a provincial-level fence may be level one, a city-level fence may be level two, a district / county-level fence may be level three, and a street-level fence may be level four.

[0057] In this case, before displaying the corresponding map image according to the user's query request, the vector data processing method provided in this embodiment may further include: determining the code corresponding to the target fence, wherein the target fence includes at least one level; determining the raster image corresponding to the target fence according to the code; and rendering the raster image to obtain a map image.

[0058] Taking a target fence comprising four levels of fences as an example, the codes corresponding to each level of target fence in the map image can be obtained. For instance, if the target fence contains a level-one fence A, and level-one fence A contains level-two fences B1 and B2, then A, B1, and B2 can each correspond to a code.

[0059] In one possible implementation, the system front-end can display the names corresponding to the target fences at various levels, which users can select. The system can then determine the corresponding code based on the selected name and retrieve the corresponding vector data from the database based on the code.

[0060] In an exemplary embodiment, the code can correspond to vector data. Furthermore, the raster image can be obtained by loading vector data; therefore, the code can correspond to the raster image.

[0061] In some exemplary embodiments, determining the raster image corresponding to the target fence based on the code includes: determining the vector data corresponding to the target fence based on the code; and generating the raster image based on the vector data corresponding to the target fence.

[0062] For example, a lowest level fence corresponds to one vector data. Taking the fence level as an example, which can include levels one to four, a level four fence corresponds to one vector data, while a level one to three fence can correspond to multiple vector data.

[0063] This disclosure does not limit the method of generating raster images from vector data. For example, the corresponding raster image can be obtained by loading the vector data into GIS (Geographic Information System) software or a programming environment.

[0064] In some exemplary embodiments, after determining the vector data corresponding to the target fence according to the code, the vector data processing method provided in this disclosure may further include: matching the vector data corresponding to the target fence with a corresponding mapping identifier, the mapping identifier including at least one of map ID (Identity) and layer ID; and storing the vector data corresponding to the target fence according to the mapping identifier.

[0065] In some embodiments, both map identifiers and layer identifiers can be business attributes created by the user through the system, and each user can have a unique map ID and a unique layer ID.

[0066] In one possible implementation, after obtaining the corresponding vector data via a code, the vector data can be mapped using a map ID and a layer ID, thereby storing the vector data using the map ID and layer ID. Furthermore, the vector data can be loaded to obtain the corresponding raster image.

[0067] In some exemplary embodiments, displaying a corresponding map image based on a user's query request includes: determining a mapping identifier corresponding to the query request; obtaining a raster image corresponding to the query request based on the mapping identifier; and rendering the raster image to display the resulting map image.

[0068] For example, when a user's query request is received, the corresponding raster image can be queried using the map ID and layer ID. Then, the map image can be obtained from the raster image to display the map image.

[0069] Alternatively, when a user's query request is received, the corresponding vector data can be queried using the map ID and layer ID. Then, the vector data can be loaded to obtain the corresponding raster image, which can then be rendered on the map to display the map image.

[0070] S204: When a user edits a map image, obtain the vector data corresponding to that map image.

[0071] In some exemplary embodiments, users can select and edit the fenced area in a map image. After the user completes the editing, the updated vector data can be obtained.

[0072] For example, a user can edit a map image using map tools. The fence area to be edited can include at least one fence, and the fence can be of any level.

[0073] S206, Update the vector data corresponding to the map image to obtain the updated vector data.

[0074] In an exemplary embodiment, vector data can be updated based on user editing operations. Exemplarily, the editing operation may include at least one of dragging, splitting, and merging.

[0075] S208. Based on the updated vector data, determine the updated map image.

[0076] In an exemplary embodiment, the updated vector data can be loaded and rendered to obtain an updated raster image. Then, an updated map image can be obtained based on the updated raster image.

[0077] For example, the method provided in this disclosure embodiment further includes: displaying the updated map image.

[0078] In some exemplary embodiments, the vector data processing method provided in this disclosure may further include: when the user grants AOI data permission for a target area, obtaining a raster image corresponding to the target area, wherein the target area is located within the region covered by the map image; when it is determined that the raster image corresponding to the target area will be edited, obtaining vector data corresponding to the target area; updating the vector data corresponding to the target area to obtain updated vector data; and determining the raster image corresponding to the updated target area based on the updated vector data.

[0079] For example, the target area can be any area covered by the map image. This disclosure does not limit the target area. For example, the target area can be a shopping mall, park, residential area, etc.

[0080] Taking a residential community as an example, users can activate access to the corresponding city's community AOI data through the system. After activation, users can query the raster images of the corresponding community AOI. Then, users can edit the raster images of the community AOI. For example, users can use the selection function to load the vector data corresponding to the community AOI, edit the community AOI image using map tools, and save the updated vector data. Then, an updated raster image can be generated based on the updated vector data. Finally, an updated community AOI image can be obtained from this updated raster image.

[0081] Optionally, the updated AOI image of the community can be displayed, allowing users to view it and determine whether further editing is needed.

[0082] The method provided in this disclosure can display map images to users, avoiding the transmission of vector data. Furthermore, users can edit the map images to update the corresponding vector data. Because the image data is small in size and loads quickly, this disclosure can reduce request response time, prevent system performance degradation, improve data transmission stability, and avoid service unavailability issues caused by interface timeouts.

[0083] For example, a schematic diagram of a vector data processing process can be as follows: Figure 3 As shown.

[0084] In Figure 3 In the system, users can create maps and polygon layers. For example, this polygon layer can be an overlayable polygon layer. An overlayable polygon layer can be a two-dimensional or multi-dimensional polygon layer that is displayed together with other layers in a GIS system. Such layers typically contain geospatial data and can be overlaid with other types of layers to create a richer and more detailed geospatial view.

[0085] Then, you can load target fences at various levels. First, confirm whether to load the first-level target fence. If not, you can view the fence information. If yes, proceed to confirm whether to load the second-level target fence. If no, you can view the fence information. If yes, proceed to confirm whether to load the third-level target fence. If no, you can view the fence information. If yes, proceed to confirm whether to load the fourth-level target fence.

[0086] Next, users can view the fence information to determine whether to edit the fence. If so, they can load the vector data and then edit it to update it. Finally, the vector data can be published as a map image and saved.

[0087] For example, a schematic diagram of a process for loading vector data corresponding to a target fence can be as follows: Figure 4 As shown.

[0088] In Figure 4 The process begins by acquiring target fences at each level. Then, the first-level target fence is loaded, and a raster image of that fence is generated. The user can then view the loaded first-level target fence and decide whether to edit it. If not, the process ends. If yes, the user selects the fence area to be edited using a selection box, and vector data is returned. Editing can then be performed based on the returned vector data, and a new raster image of the first-level target fence is generated after editing.

[0089] In an exemplary embodiment, a map image can be as follows: Figure 5 As shown. In this Figure 5 The system can display target fences at various levels. For example, a provincial fence can be a level one fence, a city-level fence can be a level two fence, a district / county-level fence can be a level three fence, and a street-level fence can be a level four fence.

[0090] For example, a schematic diagram of a vector data processing process can be as follows: Figure 6 As shown.

[0091] In Figure 6 First, users can grant access to the AOI data for their chosen city and view the AOI raster image fence. Then, a decision is made whether to edit; if not, the process ends. If so, the AOI to be edited is selected using a selection box, and vector data is returned. Editing can then be performed based on the returned vector data, and the vector data for that city's AOI is saved after editing. A new raster image of the corresponding fence is then generated. Users can then view the updated AOI raster image fence.

[0092] Among them, AOI vector data can be preprocessed and published as raster images, and when viewing the AOI raster image fence, the corresponding image set can be segmented according to the front-end scaling level.

[0093] For example, a map image can be as follows Figure 7 As shown. In this Figure 7 The black portion in the diagram can represent the area of ​​the target fence after it has been edited and updated. For example, different levels of target fences can also be distinguished by different colors or different shades of gray, but this disclosure does not limit this aspect.

[0094] The method provided in this disclosure allows the system to process and convert vector data after acquisition, transforming it into a visualized image format. By converting vector data into images, the system can significantly reduce the amount of data transmitted. Since transmitting vector data requires a large data bandwidth, converting it into images only requires transmitting the image data, resulting in a substantial reduction in data volume compared to the original vector data. This effectively reduces bandwidth pressure during transmission, improving service performance and response speed. Furthermore, during queries, the system loads and displays corresponding raster images based on the user's needs. Because raster images have a small file size and load relatively quickly, users can rapidly obtain the required geographic information data. Simultaneously, since the image data is already in a visualized form, users can intuitively observe and analyze geographic information, eliminating the need for complex processing and parsing of vector data.

[0095] It should be noted that the vector data transmission and loading method provided in this disclosure can improve the performance of geographic information services and the user experience. This disclosure achieves image-based geographic information display by combining raster images and vector data. Users can quickly obtain the required geographic information through simple data interaction and query operations, reducing the complexity of data transmission and processing, and improving the efficiency and accuracy of data display. This method can effectively optimize the performance of geographic information services, enabling users to more conveniently obtain target information.

[0096] It should be noted that the acquisition, storage, use, and processing of data in this disclosed technical solution comply with the relevant provisions of national laws and regulations. The various types of data, such as personal identity data, operational data, and behavioral data related to individuals, customers, and groups, obtained in the embodiments of this disclosure have all been authorized.
