Traditional investment promotion display methods often rely on paper maps, text descriptions or simple electronic maps, which have many shortcomings in information display, data update or interactive experience.

[0003] At present, investment promotion systems with integrated map functions have appeared, but these investment promotion systems still have many problems in actual operation, especially in the analysis of the overall layout of enterprises. First of all, from the user experience, the existing investment promotion systems have limitations in the map function. When users use maps for investment promotion analysis, it is difficult to intuitively understand the distribution of the number of enterprises in different regions. The information display is not intuitive, which not only increases the difficulty for users to understand the overall development of the region, but also reduces the efficiency of the overall investment promotion activities, causing users to spend a lot of time and energy to organize and analyze data in order to obtain a relatively accurate enterprise layout. Secondly, the map of the existing investment promotion system only has a display function for one level of enterprise information, and cannot be further refined for sub-regions, resulting in users being unable to deeply understand the enterprise information of a certain area through the map, and can only obtain the required enterprise information by constantly switching and querying different data sources.

[0020] In the specific steps of the geocoding-based investment promotion map drawing method, various embodiments of the present disclosure will be described in detail below. The present disclosure may have various embodiments, and adjustments and changes may be made therein. However, it should be understood that there is no intention to limit the various embodiments of the present disclosure to the specific embodiments disclosed herein, but the present disclosure should be understood to cover all adjustments, equivalents and / or alternatives that fall within the spirit and scope of the various embodiments of the present disclosure.

[0021] For example, in investment promotion activities, in order to attract investors or competent authorities, it is crucial to fully display regional industries, enterprises and surrounding environment information. However, traditional investment promotion display methods, such as paper maps, text descriptions or basic electronic maps, have obvious shortcomings in information presentation, real-time data updates and user interactive experience.

[0022] Although there are investment promotion systems with integrated map functions, these systems still face many challenges in actual application, especially in the in-depth analysis of the overall layout of enterprises. From the perspective of user experience, the map function of the existing investment promotion system is still insufficient. When users use maps for investment promotion analysis, it is difficult to intuitively grasp the distribution of the number of enterprises in different regions, and the display of information is not intuitive enough, which not only increases the difficulty for users to understand the overall development status of the region, but also slows down the pace of the entire investment promotion activity. Users often need to spend a lot of time and energy to organize and analyze data in order to barely obtain a relatively accurate picture of the enterprise layout.

[0023] In addition, the map function of the existing investment promotion system usually only displays corporate information at a single level and cannot be further refined to sub-regions, which limits the user's ability to gain in-depth understanding of corporate information in a specific area through the map. Users have to frequently switch and query different data sources to obtain the required corporate information, which undoubtedly reduces work efficiency and user experience.

[0024] In response to the above problems, this embodiment provides a geocoding-based investment promotion map drawing and method, which greatly improves the efficiency of drawing investment promotion maps through automated address coordinate conversion and map drawing technology. By utilizing the latest geocoding services, the accuracy of the enterprise locations on the investment promotion map is ensured. Users can quickly obtain industrial investment promotion maps, thereby improving user experience.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] See also Figure 1 The figure is a flow chart of a method for drawing an investment attraction map based on geocoding in a specific embodiment, the method comprising: S1. Establish an enterprise database for the investment promotion area, obtain enterprise information in the enterprise database, and geocode the enterprise address in the enterprise information to obtain the enterprise geographic coordinates; It should be noted that enterprise information is obtained through system entry, offline import, third-party system member download, data crawling, etc.; these addresses are converted into geographic coordinates through geocoding technology so that they can be accurately located on the map; S2. Obtain enterprise information in the enterprise database, and perform address resolution and aggregation on the enterprise addresses in the enterprise information to obtain administrative division codes of various levels of the region to which the enterprise belongs; It should be noted that obtaining administrative division codes at all levels through address aggregation helps to understand the distribution and ownership of enterprises in geographical space; S3. Summarize the enterprise information of each level for each level of administrative division code in the investment promotion area, and store the summary results; It should be noted that the enterprise information at the corresponding level can be obtained through administrative division codes; S4. Respond to the user's hierarchical display request to render the corresponding hierarchical summary of enterprise information for the investment map, and respond to the user's enterprise display request under the lowest level display request, and render the enterprise location according to the enterprise's geographic coordinates; It should be noted that through interactive map display, users can easily understand the layout and distribution of enterprises in the investment promotion area.

[0027] This application provides a method for drawing investment promotion maps based on geocoding. By creating an enterprise library, address resolution aggregation, hierarchical aggregation and dynamic rendering, it realizes the automatic drawing of investment promotion maps, reduces the cost of map drawing, improves map drawing efficiency, enhances interactivity and practicality, and solves the problem of map service differences, thereby improving system compatibility and scalability.

[0028] Further, as a refinement and extension of the specific implementation of the above embodiment, in order to fully illustrate the specific implementation process of this embodiment, another method for drawing a business investment map based on geocoding is provided, such as Figure 2 As shown, the method comprises the following steps: S1. Establish an enterprise database for the investment promotion area, obtain enterprise information in the enterprise database, and geocode the enterprise address in the enterprise information to obtain the enterprise geographic coordinates; the specific steps of step S1 are as follows: S11. Determine the investment attraction area and all enterprises within the investment attraction area; S12. Obtain enterprise information of each enterprise in the investment promotion area and establish an enterprise database; the enterprise information includes the registered address of the enterprise; S13. Building a unified geocoding request formatting service based on the geocoding methods of various map service providers; S14. Obtain the registered address of the enterprise, determine the target map service provider, call the unified geocoding formatting request service for formatting, input the target map service provider for geocoding, and obtain the geographic coordinates of the enterprise; It should be noted that by establishing an enterprise database and performing geocoding, the accuracy of enterprise information and the reliability of geographic coordinates are ensured, providing a basis for subsequent enterprise information display; S2. Obtain enterprise information in the enterprise database, and perform address resolution aggregation on the enterprise addresses in the enterprise information to obtain administrative division codes of various levels of the region to which the enterprise belongs; the specific steps of step S2 are as follows: S21. Obtain the registered address of each enterprise in the enterprise database; for example, the format of the enterprise registration address may be No. XX, XX Road (Street), XX District (County), XX City, XX Province; S22. Building a unified address resolution aggregation request formatting service based on the address resolution aggregation methods of various map service providers; the map service providers may be Baidu Maps, Amap, Tencent Maps, and Tiandi Maps; S23. Obtain the registered address of the enterprise, determine the target map service provider, call the unified address resolution aggregation request service for formatting, input the target map service provider for address resolution aggregation, and obtain the administrative division codes of each level of the area to which the enterprise belongs; It should be noted that address resolution aggregation can obtain administrative division codes at all levels of the region where the enterprise belongs, providing key data for subsequent enterprise information aggregation and display; S3. Summarize the enterprise information of each level of the administrative division code of each level of the investment promotion area and store the summary results; the specific steps of step S3 are as follows: S31. Determine the administrative division level within the investment promotion area and summarize the enterprise information of the entire investment promotion area; S32. Group and summarize the enterprise information in each highest level administrative division area according to the highest level administrative division code, and count the number of highest level administrative division areas; S33. Locate each highest level administrative division area; S34. For the highest level administrative division area located, the enterprise information of each level of administrative division is summarized in descending order according to the administrative division code of that level, until the enterprise information of the lowest level administrative division area is summarized; S35. The auxiliary investment information of each enterprise in the investment area is counted and saved in the database; It should be noted that by summarizing and counting the information of enterprises in the investment promotion area, we can fully understand the distribution of enterprises at different levels in the investment promotion area, and provide strong support for investment promotion decisions; Exemplarily, the auxiliary investment promotion information includes traffic conditions and surrounding facilities; S4. Respond to the user's hierarchical display request to render the corresponding hierarchical summary of enterprise information for the investment map, and respond to the user's enterprise display request under the lowest level display request, and render the enterprise location according to the enterprise's geographic coordinates; the specific steps of step S4 are as follows: S41. In response to the user's request to display the investment map, the map of the overall investment area is rendered at the minimum scale by default, and the text is rendered to display the overall summary of corporate information in the investment area; S42. responding to the user's highest level display request, identifying the area of ​​the highest level administrative division selected by the user, zooming in and rendering it according to a preset ratio, and rendering text to display the aggregated enterprise information in the area of ​​the selected highest level administrative division; S43. responding to the user's request for displaying the next level, identifying the area of ​​the next level administrative division selected by the user, zooming in and rendering according to a preset ratio, and rendering text to display the aggregated enterprise information in the area of ​​the selected next level administrative division; S44.

[0029] In an embodiment of the present invention, based on step S13 and step S14, a possible embodiment is given below to illustrate its specific implementation scheme in a non-limiting manner.

[0030] The specific steps of step S13 are as follows: S131. Determine the standard format of the enterprise's registered address; S132. Establish a geographic coding request generation module for each map service provider; S133. Establish a first address conversion module to convert the registered addresses of enterprises that do not conform to the standard format; Exemplarily, since the registered addresses of many enterprises are not standardized, address formatting is required before conversion. For example, many registered addresses are 1#, 2#, etc., and this information needs to be formatted as Building 1, Building 2 to meet the requirements; S134. Establish a first map service provider selection module; S135. Integrate the first address conversion module, the first map service provider selection module, and each geographic coding request generation module into a geographic coding request formatting service, with the enterprise's registered address as the input and the geographic coding request as the output; It should be noted that since the geographic coding services of each map service provider are different, the geographic coding request formatting service created here solves the problems of different URL request addresses, request parameters, return bodies, and secret key verification mechanisms in the geographic coding APIs of multiple service providers, achieving consistent input parameters, consistent output return bodies, and allowing dynamic specification of map service providers; Taking Baidu Map and Tencent Map as an example for comparison, for example: For the Baidu Map geographic coding API, its request method is: baidu-url?output=json&extension_analys_level=true&address=address&ak=secret key&city=city where it belongs; where output is the specified data format as json, extension_analys_level is a required fixed parameter, address is the enterprise address, and the data format of this address can be XX Province XX City XX District (County) XX Road (Street) XX Number, ak is the access secret key applied for in the Baidu Open Platform, and city is the city where the address belongs; For the Tencent Map geographic coding API, its request method is: tengxun-url?output=json&address=address&key=secret key; where output is the specified data format as json, address is the enterprise address, and the data format of this address can be XX Province XX City XX District (County) XX Road (Street) XX Number, and key is the access secret key applied for in the Tencent Open Platform; Since different map service providers define geocoding APIs differently, the geocoding request formatting service is compatible with the geocoding APIs provided by various map service providers. When using it, you only need to specify the company address and the map provider enumeration value to be used. For example, Baidu Map needs to specify the enumeration value as BD, Tencent Map needs to specify the enumeration value as TX, Amap needs to specify the enumeration value as GD, and Tiandi Map needs to specify the enumeration value as TDT. The key is applied for in advance from the map service provider and placed in the corresponding geocoding request generation module; The specific steps of step S14 are as follows: S141. Obtain the registered address of the enterprise and the selected target map service provider; S142. Determine whether the registered address of the enterprise conforms to the standard format through the first address conversion module; If yes, go to step S143; If not, convert the company's registered address to a standard format; S143. Select the corresponding map service provider according to the selected target map service provider and select the corresponding map service provider through the first map service provider selection module; S144. Use the geocoding request generation module corresponding to the selected map service provider to perform geocoding, obtain the longitude and latitude as geographic coordinates, and save them in the database; It should be noted that, similar to geocoding, the address resolution aggregation service APIs provided by existing address resolution aggregation service providers, such as Baidu Map, Amap, Tencent Map, and Tiandi Map, are different. Therefore, an address resolution aggregation formatting service is created to solve the different problems of URL request addresses, request parameters, return bodies, and secret key verification mechanisms in the address resolution aggregation service APIs of multiple service providers, so as to achieve consistent entry parameters and exit return bodies, and dynamically specify service providers. Specifically, you only need to specify the company address and the map vendor enumeration value to be used. For example, Baidu Map needs to specify the enumeration value as BD, Tencent Map needs to specify the enumeration value as TX, Amap needs to specify the enumeration value as GD, and Tiandi Map needs to specify the enumeration value as TDT. By constructing a unified geocoding request formatting service in detail, the differences in geocoding methods among different map service providers are solved, and the efficiency and accuracy of geocoding are improved.

[0031] In an embodiment of the present invention, based on step S22 and step S23, a possible embodiment is given below to illustrate its specific implementation scheme in a non-limiting manner.

[0032] The specific steps of step S22 are as follows: S221. Determine the standard format for the registered address of an enterprise; S222. Establish an address resolution aggregation request generation module for each map service provider; S223. Establish a second address conversion module to convert the registered address of the enterprise that does not conform to the standard format; S224. Establish a second map service provider selection module; S225. Integrate the second address conversion module, the second map service provider selection module and each address resolution aggregation request generation module into an address resolution aggregation request formatting service, and use the registered address of the enterprise as input and the address resolution aggregation request as output; The specific steps of step S23 are as follows: S231. Obtain the registered address of the enterprise and the selected target map service provider; S232. Determine whether the registered address of the enterprise conforms to the standard format through the second address conversion module; If yes, go to step S233; If not, convert the company's registered address to a standard format; S233. Select the corresponding map service provider according to the selected target map service provider and select the corresponding map service provider through the second map service provider selection module; S234. Use the address resolution aggregation request generation module corresponding to the selected map service provider to perform address resolution aggregation, obtain the administrative division codes of each level of the area to which the enterprise belongs, and save them in the database; It should be noted that, through the detailed construction process of the address resolution aggregation request formatting service, the problem of differences in address resolution aggregation methods among different map service providers is solved, and the efficiency and accuracy of address resolution aggregation are improved.

[0033] A provincial administrative region carried out comprehensive investment promotion activities within its jurisdiction. In order to more effectively show the enterprise layout and regional characteristics of the province to potential investors, it decided to adopt an investment promotion map drawing method based on geocoding.

[0036] By implementing the above-mentioned geocoding-based investment promotion map drawing method, the provincial administrative division displays the enterprise layout and auxiliary investment promotion information of the entire province through the investment promotion map. Users can intuitively understand the number and distribution of enterprises in each city, district and county, as well as the specific information and regional characteristics of the enterprises. This not only improves the efficiency and accuracy of investment promotion activities, but also reduces the cost of data collation and analysis.

[0037] It should be understood that the order of execution of the steps in the above embodiment does not necessarily mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiment of the present invention.
