Detailed Description
Exemplary embodiments of the present application will now be described with reference to the accompanying drawings, in which various details of the embodiments of the present application are included to facilitate understanding, and are to be considered merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
Address description methods, apparatuses, electronic devices, and storage media according to embodiments of the present application are described below with reference to the accompanying drawings.
Fig. 1 is a flowchart of an address description method according to a first embodiment of the present application.
In practical application, the map is not fine enough to describe the address, and in general, only the range polygon data and administrative division codes of the four-level administrative area plan are provided in the map, and the description and range data of the five-level administrative area plan of the next level are not provided, and only the user address is very thick by the four-level administrative area street/village and town description, so that whether the user address is a rural area or a town cannot be judged, and in addition, for example, the five-level administrative area of China comprises a urban area, a town area, a village and the like, and the information acquisition and updating cost is high.
Aiming at the problems, the application provides an address description method which does not need to collect range data of five-level administrative areas, combines a map to accurately acquire urban and rural classification description information of which geographic coordinate information belongs to urban areas or rural areas with lower cost based on the existing internet data, map user use data, track data and the like, and improves the address description efficiency.
Specifically, as shown in fig. 1, the address description method may include the steps of:
step 101, obtaining geographic coordinate information, and obtaining a current level administrative region which is set corresponding to the geographic coordinate information on a map and information points of a next level administrative region which is identified in the current level administrative region.
In the embodiment of the present application, there are various ways of obtaining the geographic coordinate information, which can be selected according to a specific application scenario, and as an example, the geographic coordinate information (such as longitude and latitude information of a location) can be directly obtained through a positioning module such as a global positioning system; as another example, text address information entered by a user in a map is received, and the text address information is converted into geographic coordinate information by a geocoding service.
In the embodiment of the application, after the geographic coordinate information is acquired, the current level administrative region which is arranged corresponding to the geographic coordinate information on the map can be acquired, and it can be understood that in practical application, the first-level administrative region comprises provinces, autonomous regions, direct administration cities and special administrative regions; the second administrative areas comprise ground cities, regions, autonomous states and allies; the third-level administrative areas comprise municipal areas, county-level cities, counties, autonomous counties, flags, autonomous flags, forest areas and special areas; four-level administrative district: including streets, towns, villages, nations, sappan wood, nations sappan wood, county jurisdictions, four-level administrative areas set corresponding to geographic coordinate information can be generally located in the map.
Therefore, the current level administrative area, namely the four-level administrative area, set corresponding to the geographic coordinate information on the map can be obtained according to the geographic coordinate information, but the geographic coordinate information is very coarse directly according to the four-level administrative area, and whether the geographic coordinate information is rural or urban cannot be judged, so that the information point of the next level administrative area identified in the current level administrative area is obtained.
It will be appreciated that the information points of the next level administrative area identified in the current level administrative area are typically information points such as information point 1 labeled as the large willow village commission, information point 2 as the market street community commission, etc. that are reported by users in various maps (e.g., hundred degree maps, high-germany maps, etc.).
It should be noted that in the embodiment of the present application, it is mainly aimed at how the five-level administrative region carries out the accurate urban and rural classification description information, so that the current-level administrative region is generally a four-level administrative region, and the next-level administrative region is a five-level administrative region.
Step 102, inquiring a preset database, acquiring urban and rural classification identifiers of the administrative region of the next level, and judging whether the urban and rural classification identifiers belong to the same type.
And step 103, if the urban and rural classification identifiers are not of the same type, constructing a Veno diagram according to the information points of the administrative region of the next level, and matching the corresponding target region in the Veno diagram according to the geographic coordinate information.
Specifically, the relevant information is generally associated with the national statistical bureau according to the administrative division codes, and in the application, all the next-level administrative area information under the current-level administrative area can be obtained from the national statistical bureau database through the current-level administrative area (such as four-level administrative area) codes, and the urban and rural classification identifiers are stored in the preset database.
If the urban and rural classification identifiers are of the same type, urban and rural classification description information of the urban and rural classification identifiers is obtained and output, so that the urban and rural classification description information of the urban and rural classification identifiers is directly determined to be of the same type according to the urban and rural classification identifiers, and the address description efficiency is improved.
For example, taking the camping county of the Yangqing area in Beijing city as an example, five-level administrative areas of the next level of the four-level administrative areas, such as urban and rural classification identifiers from the camping county of the five-level administrative areas, are 220 and 210, which belong to the same type: rural areas.
Therefore, even if there is no five-level administrative area range data of each village committee, it can be precisely determined that if the geographical coordinate information falls in the camping and rural areas, 100% of addresses for which the geographical coordinate information can be determined are the rural areas, and it is also understood that the urban and rural classification identifications are not of the same type and need to be further processed.
Specifically, if it is known that urban and rural classification identifiers do not belong to the same type, a voronoi diagram is constructed according to information points of a next-level administrative region, wherein various manners of constructing the voronoi diagram according to information points of the next-level administrative region are available, and the configuration can be selected according to needs.
As one possible implementation manner, a triangle network is constructed according to the information points of the administrative region of the next level, the circle center of the circumscribed circle of each triangle in the triangle network is calculated, the triangle network is traversed, if the adjacent triangle with any side of the current triangle as the common side is acquired, the connecting line between the circle center of the circumscribed circle of the adjacent triangle and the circle center of the circumscribed circle of the current triangle is stored in the voronoi edge linked list, if the adjacent triangle with any side of the current triangle as the common side is not acquired, the ray of the perpendicular bisector of the outermost edge of the current triangle is calculated and stored in the voronoi edge linked list, and the traversing is finished according to the voronoi Bian Goujian voronoi diagram in the voronoi edge linked list.
Further, in matching corresponding target areas in the voronoi diagram according to the geographic coordinate information, that is, according to the information points of the administrative area of the next level, the voronoi diagram includes a plurality of areas, each area corresponds to urban and rural classification description information, for example, area 1 is XX village commission, area 2 is XX urban area, and the like, and the target area corresponding to the geographic coordinate information, for example, area 1, can be searched.
And 104, judging whether the number of urban and rural classification identifiers of the administrative region of the next level is consistent with the number of information points of the administrative region of the next level.
And 105, if the number of the urban and rural classification identifiers is consistent with the number of the information points, acquiring and outputting urban and rural classification description information of the target area in the map.
In the embodiment of the application, the information points of the administrative region of the next level are generally original by users and are not necessarily comprehensive enough, so that the number of urban and rural classification identifiers of the administrative region of the next level may be consistent with or inconsistent with the number of the information points of the administrative region of the next level, and therefore, if the number of the urban and rural classification identifiers is known to be consistent with the number of the information points, the coverage of the information points of the administrative region of the next level is complete, and thus, urban and rural classification description information of a target region in a map is acquired and output, that is, the target region corresponding to geographic coordinate information is, for example, region 1, which is the XX committee, and the address of the geographic coordinate information can be determined as the rural region.
In summary, according to the address description method of the present application, by obtaining the geographic coordinate information, and obtaining the current level administrative region set corresponding to the geographic coordinate information on the map, and the information points of the next level administrative region identified in the current level administrative region; inquiring a preset database, acquiring urban and rural classification identifiers of the administrative region of the next level, and judging whether the urban and rural classification identifiers belong to the same type; if the urban and rural classification identifiers are not of the same type, constructing a Veno diagram according to the information points of the administrative region of the next level, and matching the corresponding target region in the Veno diagram according to the geographic coordinate information; judging whether the number of urban and rural classification identifiers of the administrative region of the next level is consistent with the number of information points of the administrative region of the next level; if the number of the urban and rural classification identifications is consistent with the number of the information points, urban and rural classification description information of the target area in the map is acquired and output. Therefore, the urban and rural classification description information of the urban area or the rural area of the geographic coordinate information can be accurately obtained at low cost, and the address description efficiency is improved.
Based on the description of the above embodiment, it may be understood that the number of urban and rural classification identifiers of the administrative region of the next level is consistent with the number of information points of the administrative region of the next level, and urban and rural classification description information of the target region in the map is directly obtained and output, and if the number of urban and rural classification identifiers of the administrative region of the next level is inconsistent with the number of information points of the administrative region of the next level, further judgment needs to be performed, which is described in detail below in conjunction with fig. 2.
Fig. 2 is a flowchart of an address description method according to a second embodiment of the present application.
Specifically, as shown in fig. 2, the address description method may further include the following steps after step 104:
step 201, if the number of urban and rural classification identifiers is inconsistent with the number of information points, acquiring the development index of the administrative region at the current level.
In the embodiment of the application, if the number of the urban and rural classification identifiers is not consistent with the number of the information points, the information points in the administrative region of the next level do not comprise all the urban and rural classification identifiers, and the construction of the voronoi diagram according to the information points in the administrative region of the next level is incomplete, namely, the condition that the information points in the map are missing and the voronoi diagram is not fully depicted exists.
Therefore, the development index of the current level administrative region is further obtained, the geographical position of the current level administrative region in China can be marked according to the population total number, the domestic production total value and other data of the current level administrative region on the Internet, and meanwhile, the development index of the current level administrative region is determined by utilizing the data of regional map retrieval amount, regional vehicle track density and the like.
As one possible implementation manner, the population total number, the domestic production total value and the search times and the travel times of the current level administrative region in the map are obtained, and the development index of the current level administrative region is determined according to the population total number, the domestic production total value and the search times and the travel times of the current level administrative region in the map.
For example, developed indexes such as population total greater than X, domestic production total greater than 11, and current level administrative regions searching times greater than Z and traveling times greater than W in the map are first indexes; the developed indexes of population total number between R-X, domestic production total value between S-11, searching times T-Z of the current level administrative region in the map and traveling times between U-W are second indexes, namely different threshold intervals are respectively set for different developed indexes, and the developed indexes of the current level administrative region are determined through judgment of each numerical value. The development indexes of the administrative regions of different levels are expressed by different development indexes, and the development indexes of the administrative regions of the current level are directly obtained based on the existing data, so that the geographic coordinate information is determined to belong to urban areas or urban and rural classification description information of rural areas according to the auxiliary determination of the development indexes, and the address description efficiency is improved.
And 202, determining and outputting target urban and rural classification description information according to the developed index and the voronoi diagram of the administrative region of the current level.
As one possible implementation, first urban and rural classification description information corresponding to the developed index of the administrative region of the current level is acquired, a plurality of adjacent regions of the target region are acquired from the voronoi diagram, second urban and rural classification description information of the plurality of adjacent regions in the map is acquired, and the target urban and rural classification description information is determined and output according to the first urban and rural classification description information and the second urban and rural classification description information.
In the embodiment of the application, when the developed index of the administrative region according to the current level is, for example, a fifth index, is a rural region, and then the target region matched with the geographic coordinate information is obtained from the voronoi diagram, because the voronoi diagram is incomplete, urban and rural classification description information of one or more adjacent regions of the target region can be determined to be the rural region according to the urban and rural classification description information of the geographic coordinate information, for example, all the rural regions can be determined, if some rural regions of the urban and rural classification description information are, and some rural regions are urban regions, the target urban and rural classification description information can be calculated and determined according to the set weight information and output.
Therefore, if the number of urban and rural classification identifiers is inconsistent with the number of information points, the developed index of the current level administrative region is obtained, the target urban and rural classification description information is determined and output according to the developed index of the current level administrative region and the voronoi diagram, and the urban and rural classification description information of which the geographic coordinate information belongs to urban areas or rural areas can be accurately obtained by combining the developed index of the current level administrative region, so that the address description efficiency is improved.
In order to more fully describe the address description method of the present application, the current level administrative region is taken as a four-level administrative region, the next level administrative region is taken as a five-level administrative region as an example, and the detailed description is described with reference to fig. 3.
Fig. 3 is a flowchart of an address description method according to a third embodiment of the present application.
Specifically, as shown in fig. 3, the address description method may include the steps of:
step 301, obtaining geographic coordinate information, and obtaining a four-level administrative region corresponding to the geographic coordinate information on a map, and obtaining urban and rural classification identifiers of five-level administrative regions.
In the embodiment of the application, the text address can be acquired or the geographic coordinate information can be directly acquired, and under the condition of acquiring the text address, the geographic coding service provided by the map can be called to convert the text address into the geographic coordinate information.
Further, four-level administrative regions corresponding to the geographic coordinate information on the map are acquired, that is, four-level administrative regions corresponding to the geographic coordinate information are searched on the map, for example, four-level administrative regions corresponding to the longitude a and the latitude b are 1, and the like.
And step 302, if the urban and rural classification identifiers are known to be of the same type, acquiring and outputting urban and rural classification description information of the urban and rural classification identifiers.
Specifically, through the four-level administrative area codes in the map, the four-level administrative area codes can be associated with the four-level administrative area of the national statistical bureau, so that all five-level administrative area information and urban and rural classification identifications in the four-level administrative area are acquired, the lower five-level administrative area is 220 and 210 from the urban and rural classification codes in the urban and rural areas as shown in fig. 4, namely, even if five-level administrative area range data of each village commission are not available, if the geographic coordinate information falls in the urban and rural areas, the geographic coordinate information can be accurately determined to be the rural area in hundred percent.
Therefore, according to the data statistics analysis result of the statistical office information, most of the geographic coordinate information can be obtained to be whether the geographic coordinate information is a country or a city only through the four-level administrative region to which the real address coordinate belongs (namely, the geographic coordinate information can be determined through the inside and outside algorithm of the point in the polygon).
Step 303, if it is known that the urban and rural classification identifiers are not of the same type, a voronoi diagram is constructed according to the information points of the administrative region of the next level, and the corresponding target regions are matched in the voronoi diagram according to the geographic coordinate information.
And step 304, if the number of the urban and rural classification identifiers is consistent with the number of the information points, acquiring and outputting urban and rural classification description information of the target area in the map.
It can be further understood that there are cases where urban and rural classification identifiers are not of the same type, and the lower five-level administrative district is shown in fig. 5 when seen from the small Shang Shanzhen of the Changping district of Beijing city, and the small Shang Shan town is relatively complex in construction when seen from the urban and rural classification identifiers, and has urban areas and also has town areas, so that it is impossible to directly confirm whether the geographic coordinate information is in village or town areas.
For the region in the above example, although the cost of collecting range data is relatively high, each map has a way of reporting coordinate point data (information points) by original content of a user, so that a large number of information points in five-level administrative areas can be obtained, and as shown in fig. 6, the information point marks 7 are information points reported by the user and the like.
Aiming at the situation, a Veno diagram can be constructed according to the information points of the administrative region of the next level, corresponding target regions are matched in the Veno diagram according to the geographic coordinate information, the number of urban and rural classification identifiers is known to be consistent with the number of the information points, and urban and rural classification description information of the target regions in the map is acquired and output.
That is, if the data coverage of the information points is complete, as can be seen from the characteristics of the voronoi diagram shown in fig. 7 (the information points in fig. 7 are completely identified), the five-level administrative region where the geographic coordinate information is located is the address closest to the geographic coordinate information, and if the surrounding regions of the points where the geographic coordinate information is located are villages, the great probability is that the villages are villages.
The triangle network can be constructed according to the information points of the administrative region of the next level, the circle center of the circumscribed circle of each triangle in the triangle network is calculated, the triangle network is traversed, if the adjacent triangle with any side of the current triangle as the public side is acquired, the connecting line between the circle center of the circumscribed circle of the adjacent triangle and the circle center of the circumscribed circle of the current triangle is stored in the Veno edge linked list, if the adjacent triangle with any side of the current triangle as the public side is not acquired, the perpendicular bisector ray of the outermost edge of the current triangle is calculated and stored in the Veno edge linked list, the traversing is finished, and the Veno Bian Goujian Veno diagram in the Veno edge linked list is quickly constructed according to the information points, so that the urban and rural classification description information with geographic coordinate information belonging to urban areas or rural areas is acquired in an auxiliary manner, and the address description efficiency is improved.
And 305, if the number of the urban and rural classification identifiers is inconsistent with the number of the information points, acquiring the development index of the administrative region at the current level.
And step 306, determining and outputting the target urban and rural classification description information according to the developed index and the voronoi diagram of the administrative region of the current level.
It can be further understood that the situation that the information points in the map are missing and the voronoi diagram is not fully depicted exists, and for the situation, the data such as population total number and domestic production total value of the four-level administrative region on the internet are further grasped, the geographical position of the four-level administrative region in China is marked, meanwhile, the map retrieval times, the vehicle or user track density and other data are utilized to construct the developed index of the four-level administrative region, and the surrounding reference situation obtained by combining with the voronoi diagram is comprehensively presumed whether the geographical coordinate information is in rural areas or towns.
For example, urban areas corresponding to the development indexes of the four-level administrative areas are acquired, a plurality of adjacent areas of the target area are acquired from the voronoi diagram, and all of the plurality of adjacent areas in the map are acquired as urban areas, so that the target urban and rural classification description information is determined as the urban areas and output.
In summary, according to the address description method of the present application, geographic coordinate information is obtained, four-level administrative regions corresponding to the geographic coordinate information are obtained on a map, urban and rural classification identifiers of five-level administrative regions are obtained, if the urban and rural classification identifiers are obtained to be of the same type, urban and rural classification description information of the urban and rural classification identifiers is obtained and output, if the urban and rural classification identifiers are obtained to be not of the same type, a voronoi diagram is constructed according to information points of a next-level administrative region, and corresponding target regions are matched in the voronoi diagram according to the geographic coordinate information, if the number of the urban and rural classification identifiers is obtained to be consistent with the number of the information points, urban and rural classification description information of the target regions in the map is obtained and output, if the number of the urban and rural classification identifiers is obtained to be inconsistent with the number of the information points, a developed index of the current-level administrative region is obtained, and the target urban and rural classification description information is determined and output according to the developed index and the voronoi diagram of the current-level administrative region.
