A Spatial Data Matching Method for Specialized Pipelines and Comprehensive Pipelines of Urban Water Supply

Abstract

The invention discloses a spatial data matching method for urban water supply professional pipelines and comprehensive pipelines. The method includes: analyzing the difference between the spatial data of urban water supply comprehensive pipelines and the professional pipeline spatial data, and performing data preprocessing on the pipeline data; taking into account Based on the Stroke characteristics of the water supply network and the structural characteristics of the water supply network, the skeleton line of the water supply network is generated; the characteristic factors are selected to match the skeleton lines of the two types of pipelines, and the matching results of key structural points of the water supply network are generated according to the matching results of the skeleton lines; the similarity is selected Factor, calculate the similarity result of pipe point matching, generate the pipe point matching result set by manually setting the threshold, and finally complete the pipeline matching according to the pipe point matching result. Aiming at the problem of "two copies of data, repeated detection" existing in urban underground pipelines, the present invention uses the GIS vector space data matching method to complete the comprehensive water supply pipeline space data and professional water supply pipelines on the basis of analyzing the overall shape and structure characteristics of the water supply pipeline network Matching of spatial data.

Description

technical field [0001] The invention belongs to the field of geographic information, and in particular relates to a spatial data matching method for urban water supply professional pipelines and comprehensive pipelines. Background technique [0002] Urban underground pipelines are an important part of urban infrastructure. They are responsible for transmitting information and transporting energy. They are the material basis for the survival and development of cities. They are called the "lifeline" and "bloodline" of cities. With the construction of "smart cities", urban underground pipeline data has become an important content of underground space information resources, and has been widely used in urban planning and design, emergency event handling, underground space development and other fields. [0003] Due to the difference in management mode and application purpose, the current pipeline data is divided into two categories: comprehensive underground pipeline data and prof...

AI Technical Summary

Problems solved by technology

Due to the lack of a comprehensive underground pipeline data matching model, the lack of solutions to large-scale spatial data matching, and the lack of efficient and convenient pipeline data matching tools, relevant departments of pipelines still use inefficient manual matching methods for data matching
