Background
Under the large background of industrial digital transformation, the importance of electronic maps as infrastructure is increasingly prominent, particularly in the industries of transportation and the like, core business data of the electronic maps are all spread around the electronic maps, and different business data can be further processed and applied only by aligning time and space based on the electronic maps. Therefore, the industry data space-time management based on the electronic map is a basic problem to be solved urgently in digital transformation of industries such as transportation and the like.
At present, space-time management of industry data is generally performed by adopting a map layer manufacturing mode, as shown in fig. 1, for example, the transportation industry is taken as an example, the transportation industry data comprises data such as milepost point positions, toll gate point positions, bridge and tunnel point positions, mapping of the industry data and electronic map data is realized through the map layer manufacturing process, and the problems of low point position precision, data loss, logic errors and the like commonly existing in the industry data are solved by taking an electronic map as a carrier in the mapping process. Through the space-time management process, accurate industry data are output in a layer mode, and the position description of the industry data is associated with an electronic map (a road network layer), so that space alignment and communication among different layers of the map are realized, and the multidimensional industry data are called by an upper-layer service in a one-map form, so that the fusion application of the upper-layer service to the electronic map and the data of different industries is met.
In the existing layer making process, as shown in fig. 2, due to a plurality of problems of industry data (taking mileage pile data as an example), before mapping with an electronic map, a series of preprocessing operations such as logic inspection, data filling, position correction and the like are required to be performed on the industry data based on a general GIS platform, so as to reduce errors in mapping with the electronic map; meanwhile, because the mapping of the electronic map cannot guarantee 100% accuracy, the mapping result needs to be manually checked, and the checked problem needs to be fed back to the preprocessing stage for iterative disposal. After multiple iterations, outputting a mileage pile map layer, and describing the accurate position of the mileage pile point in the road network. In view of frequent version changes of industrial data and small proportion of data change part in total data amount each time, the general GIS platform cannot effectively record human work processes such as data preprocessing, result inspection and the like, so that the processes such as data preprocessing and the like can only be 'full' operation instead of 'incremental' operation, which causes serious manual repeated labor, thereby reducing the generation efficiency of map layer data and failing to meet the requirement of layer making with increasingly high frequency.

The method may be implemented in dependence on a computer program, operable on a map layer data generating device based on the von neumann architecture. The computer program may be integrated into the application or may run as a separate tool-like application.
Referring to fig. 3, a flowchart of a map layer data generation method is provided in an embodiment of the present application. As shown in fig. 3, the method of the embodiment of the present application may include the following steps:
s101, when the version information of the industry data is monitored to change, acquiring and preprocessing the current version industry data with the changed version information, and generating a multi-batch point bit data set;
the current industry data is generally collected and maintained by different channels and then summarized by the state or industry level. The industry data can be various, and take traffic data as an example, the industry data comprises milepost data, charging data, bridge data, tunnel data, traffic violation recording device data, intelligent traffic roadside device data and the like.
Generally, for the transportation industry, the channels are generally referred to as provincial authorities in particular, because important transportation industry data such as mileposts are generally collected and maintained by provincial authorities, although the industry data have uniform definition and format specifications in the national or industry level, the definition modes of the data by different channels have certain differences, which requires preprocessing of the industry data uploaded by different channels. The preprocessing is specifically an escape operation and a batch dividing operation of the data.
In the embodiments of the present application, the present invention defines the escape operation as
Figure BDA0003584334800000071
Wherein K is 1,2, …, and K uniquely identifies a channel of industry data; tau defines the type of the industry data,
Figure BDA0003584334800000072
and uploading the content of the industry data with the type tau for the channel k.
In the process of the industry data escaping, the invention defines the content abstraction of the industry data as a point location set. Taking the traffic industry as an example, the traffic industry data is generally provided in the form of points or lines, and by extracting key points from the lines, the invention uniformly abstracts the industry data into a set of point locations, such as milepost point locations, bridge and tunnel point locations, and the like.
The point is defined as a five tuple:
p＝<k,τ,(x,y),Ω)
wherein k defines a channel of point location; τ defines the type of data; (x, y) defines the coordinates of the point location; omega is an attribute set of point locations extracted based on industry data content, such as stake numbers, high-speed names and uplink and downlink information of mileage stake point locations; the name, type and the like of the bridge and tunnel are p, omega, E to Ck。
Channel k-based industry data

The point location set formed by the escape is recorded as

Obtaining the industry data of the current version after the version is upgraded
Figure BDA0003584334800000079
Then, according to the escape operation method recorded by the system, executing

Get the point location set after escaping
Figure BDA00035843348000000711
Carrying out full channel escape on the point location to obtain P1τ。
In the embodiment of the application, in order to improve the efficiency of making map layer data, the point position set data P are combinedτAnd (3) carrying out batch division, wherein the divided batch data are atomic units for map layer production, and the meanings of the atomic units are as follows: executing one or more rounds of map layer manufacturing operation on one batch of data, wherein the map layer manufacturing operation comprises three steps of data preprocessing, electronic map mapping and result checking; the data production operations between different batches are independent of each other.
Batch data division is an efficient data organization mode, and compared with an operation mode aiming at point positions, the efficiency of manual operation can be effectively improved. Furthermore, the batch data is used as a point location set with high cohesion and low coupling, and the high cohesion characteristic of the batch data is beneficial to improving the manufacturing precision of the map layer, for example, the mileage pile point locations in the same high speed and the same uplink and downlink direction are divided into one batch for integral map mapping, and the map mapping process has richer context semantic information than that of single mileage pile point location mapping; due to the low coupling characteristic among the batch data, the operations among different batches are mutually independent, and the multi-user division and cooperation of map layer operations are facilitated.
The invention defines the batch data partitioning operation as split (tau, P)τ) Adding batch information to the divided point location, wherein the batch information is defined as follows:
Figure BDA0003584334800000081
defining a point location batch, wherein m is a data batch number where the point location is located, and n is a serial number of the point location in the data batch number; still taking the mileage stake map layer as an example, the split operation divides the mileage stake point positions with the same high speed name and the same uplink and downlink information into the same batch number m, and determines the serial number n of the point positions in the batch after sorting according to the stake number information.
Recording the data of the same divided batch as the data of the same divided batch according to a preset data batch division rule

And P1τFor P1τPerform split (τ, P1)τ) Obtaining a multi-batch dot data set B1 comprising batch marksτ。
In a possible implementation manner, when it is monitored that version information of the industry data changes, current version industry data after the version information changes is obtained first, then, the current version industry data is subjected to escape processing according to a preset data escape rule to obtain an escaped point location set, and finally, the escaped point location set is collected according to a preset data batch division rule and subjected to batch division processing to obtain a plurality of point location data sets including batch marks.

S103, judging whether each target point data is equivalent to the point location data corresponding to the previous historical version industry data, and determining the point location data set of the batch to which the non-equivalent target point data belongs as incremental batch data;
in the embodiment of the application, when equivalence judgment is performed, a first attribute set of each target point data is obtained first, historical point data corresponding to each target point data is obtained from a point data set of the previous historical version industry data, a second attribute set of each historical point data is obtained, whether the first attribute set of each target point data is consistent with the second attribute set of each historical point data corresponding to the first attribute set of each target point data is judged, if the first attribute set of each target point data is inconsistent with the second attribute set of each historical point data, inconsistent target point data is determined, and the inconsistent target point data is used as the unequivalent target point data. And if the data is consistent with the data, the data of each target point is equivalent to the point location data corresponding to the previous historical version industry data.
Further, if the point location data in the previous historical version is consistent, the point location data in the previous historical version is called
