Abstract
Description
Technical Field
[0001] The present invention relates to the field of geographic information technology, and in particular to a spatial data analysis and processing method and system. Background Art
[0002] In recent years, with the growing demand for economic development and land and space development, services and applications in land and space planning, environmental assessment, and refined urban management have become increasingly widespread. Land and space statistical analysis is an important part of these applications. Spatial object analysis in land and space statistical analysis primarily involves performing attribute statistics and topological calculations of spatial position relationships within a specific buffer range for specific business content (such as environmental protection objects, building types, industrial types, and residential types). Combined with temporal attributes, this constitutes the statistical analysis requirements for specific objects within a specific range, providing business support for scientific decision-making and planning management. Currently, many regions in China have established basic land planning databases and business application databases, including basic data and related business data.
[0003] At present, GIS (Geographic Information System) platform software has been widely used in many provinces, but in actual use, it is found that many business applications have the need to complete the attribute statistics of the business objects of concern and the topological analysis of spatial location relationships within a specific buffer range. Among them, completing the object analysis and statistics within a specific buffer range requires not only analyzing the objects and their attributes, but also paying attention to the spatial range to which they belong, that is, setting a certain spatial buffer range for the business objects; spatial topological relationships are the basis of all spatial analysis. Many application scenario analyses require the implementation of spatial topological analysis between different elements, and statistical analysis of the number of specified attribute elements contained in the spatial range of business elements. The spatial range can be expressed as points, lines, surfaces, bodies and other shapes. However, in traditional business applications, topological relationship calculations are time-consuming, affecting user experience and computing efficiency. Summary of the Invention

[0044] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present invention.
[0045] Please refer to Figure 1 A first aspect of an embodiment of the present invention provides a spatial data analysis and processing method, comprising the following steps:
[0046] Step S100: Acquire analysis requirements of spatial data, where the analysis requirements include: analysis area, analysis object, and attribute fields.
[0047] Step S200 : obtaining a plurality of data tables in a business database related to both the analysis area and the analysis object, performing coordinate transformation on each of the plurality of data tables, and creating a spatial coordinate system corresponding to each data table.
[0048] Step S300 : Based on the spatial coordinate system corresponding to each data table, the attribute information corresponding to each analysis object and the attribute field in the analysis area is obtained, and the attribute information of the analysis object is classified and displayed according to the attribute field in the analysis area.
[0049] The present invention achieves spatial standardization of data by performing coordinate conversion on data tables in data sources and creating a spatial coordinate system, thereby solving the problem of inconsistent coordinate systems that may exist between different data sources. It also enhances the readability and visualization of data by extracting and classifying attribute information of objects in the analysis area, allowing users to intuitively understand and analyze the attribute distribution and characteristics of spatial data.
[0050] In one implementation of the present invention, after obtaining the attribute information corresponding to each analysis object and attribute field in the analysis area in step S300, the method further includes:
[0051] Step S311: converting multiple data tables into the same spatial coordinate system.
[0052] Step S312: Based on preset topology rules, a spatial topology rule check is performed on the data tables in the same spatial coordinate system to identify and repair topology errors.
[0053] Step S313: perform spatial topology analysis on the repaired data tables to establish the association between the analysis objects.
[0054] Through the above data processing process, multiple data tables are converted to the same spatial coordinate system, ensuring the consistency of the data in spatial position and eliminating errors caused by coordinate system differences; then, topology rule checking is performed based on preset topology rules, which can systematically identify topological errors in the data and improve data quality by repairing these errors; after repairing the topological errors, the spatial topological analysis can accurately establish the spatial relationship between the analysis objects, such as adjacency, intersection or inclusion, and more advanced spatial analysis can be performed, such as network analysis, overlay analysis and spatial statistical analysis.
[0055] Furthermore, the step S311 of converting the plurality of data tables into the same spatial coordinate system includes:
[0056] Step S311a: Select a spatial coordinate system of a data table as a reference coordinate system.
[0057] Step S312b: Obtain the coordinate system information of the spatial coordinate system of each other data table, and obtain the projection difference and reference plane difference between the spatial coordinate system and the reference coordinate system.
[0058] Step S313c: based on the projection difference and the reference plane difference, the spatial data in each other data table is converted into a value corresponding to the reference coordinate system.
[0059] By selecting the spatial coordinate system of one data table as the base coordinate system, a unified reference framework is provided for all data, simplifying spatial analysis and comparison across data tables. The coordinate system information of other data tables is then obtained and the projection and datum differences between them and the base coordinate system are calculated, ensuring the accuracy of the conversion process. By clearly distinguishing and processing projection and datum differences, conversion errors between different coordinate systems are effectively eliminated, improving the accuracy of spatial data. This process converts all data tables to the same base coordinate system, enhancing consistency between datasets and facilitating integrated analysis.
[0060] In another embodiment of the present invention, after obtaining the attribute information corresponding to each analysis object and attribute field in the analysis area in step S300, the method further includes:
[0061] Step S321: Acquire the same attribute fields or similar attribute fields in different data tables.
[0062] Step S322: Establish attribute associations for the same attribute fields or similar attribute fields in different data tables, and display them in the same category.
[0063] By identifying and associating the same or similar attribute fields in different data tables, it provides significant improvements in data integration, analytical depth and visualization effects, while simplifying data operation processes and enhancing data consistency; it also optimizes the execution of complex queries, promotes data reuse and sharing, and strengthens data governance to ensure data quality and accuracy.
[0064] Furthermore, after obtaining the same attribute fields or similar attribute fields in different data tables in step S322, the method further includes:
[0065] Step S323 : Based on the field names, data types and data consistency of similar attribute fields, it is determined whether the attribute fields in different data tables are the same attribute field.
[0066] Furthermore, in the above-mentioned process of determining the similarity of attribute fields, the similarity estimation value of two relatively similar attribute fields is first calculated, and then the calculation result is compared with the similarity threshold to determine whether the two similar attribute fields are the same attribute field.
[0067] When determining the threshold for comparing similarity estimates between similar attribute fields in different data tables, the primary considerations are typically business needs analysis and data characteristics assessment. Business needs analysis ensures that the threshold setting meets specific business objectives and decision-making criteria, while data characteristics assessment ensures the threshold is scientific and reasonable, taking into account data quality and consistency. Combining these two factors allows for the development of a threshold that reflects both business needs and data characteristics, thereby ensuring the accuracy and practicality of similarity comparisons.
[0068] The calculation formula for the similarity estimate of two similar attribute fields in different data tables is:
[0069] FSS=λ1×S name +λ2×S stat +λ3×S dist +λ4×S content +λ5×S semantic ;
[0070] Among them, FSS is the similarity estimation value of the attribute field, S name is the attribute field name similarity evaluation value, S stat is the statistical characteristic similarity estimate of the attribute field, S dist is the data distribution similarity estimate of the attribute field, S content is the data type similarity estimate of the attribute field, S semantic is the semantic similarity estimation value of the attribute field, and λ1, λ2, λ3, λ4, and λ5 are the weight coefficients of the corresponding estimation values.
[0071] The aforementioned attribute field name similarity evaluation values can use edit distance (such as Levenshtein distance) or Jaccard similarity coefficient to evaluate the similarity of field names; statistical characteristic similarity can be evaluated by calculating statistics such as the mean, median, variance, skewness, and kurtosis of two fields and using Euclidean distance and / or cosine similarity to evaluate the differences between them. Data distribution similarity can use the Kolmogorov-Smirnov test to evaluate the similarity of the data distributions of two fields. Data type similarity estimates can be used for numerical data and categorical data. For numerical data, the Pearson correlation coefficient or Spearman rank correlation is used to evaluate linear or nonlinear relationships; for categorical data, the Jaccard similarity or Kappa statistic is used. In addition, for semantic similarity estimates, natural language processing technologies such as word embedding or the BERT model can be used to evaluate the semantic similarity of field descriptions.
[0072] Furthermore, the statistical characteristic similarity estimate S stat The calculation formula is:
[0073]
[0074]
[0075]
[0076] Among them, θ1 is the Euclidean distance weight coefficient value, θ2 is the cosine similarity weight coefficient value, D euclidean is the Euclidean distance similarity estimate, D max is the maximum possible value of Euclidean distance similarity, S cos is the estimated value of cosine similarity, μ1 and μ2 are the means of the two similar attribute field data, M1 and M2 are the medians of the two similar attribute field data, σ1 and σ2 are the variances of the two similar attribute field data, S1 and S2 are the skewness of the two similar attribute field data, and K1 and K2 are the kurtosis of the two similar attribute field data.
[0077] Furthermore, the analysis area includes: several fixed administrative areas or several designated areas.
[0078] The following describes the spatial data analysis and processing process using a certain regional business requirement as an example:
[0079] First, all business data is brought into the regional big data center's data lake. The platform can connect to business databases on demand, achieving broad coverage of spatial computability. Second, after connecting to the business database, it can filter business tables and attribute fields within them, adding them to the platform for spatial analysis as needed. Business data is required to have spatial coordinates, achieving flexibility in spatial computability, and customizing static pages for adding data and selecting attribute fields. After selecting business tables and fields, they can be added to the analysis object layer. Third, one can freely configure and select one or more analysis objects for statistical analysis, including residential areas, buildings, stratified households, people, and / or commercial buildings as layer objects.
[0080] Furthermore, circles are divided into two parts: fixed circles (as shown in Table 1) and custom circles (as shown in Table 2). Among them, fixed circles can be selected by users in Table 1; custom circles can be drawn by users according to their interests. For example, the Hunan Road street will focus on and draw the area of the internet celebrity block.

[0087] (1) Taking the housing as an example, the report content includes basic information of the housing, such as the community, building, number of rooms, total number of people, basic information of the people (household registration, age, gender, etc.), and labels selected by the user (such as elderly people living alone).

[0089] On this basis, statistics and analysis results are presented in the form of an interface, recording the user's analysis object layer and spatial range as input parameters, and the statistics and analysis results as output, which can be shared by the business end by calling the interface. Initially, this will be implemented statically on the page.
