Spatial data matching method for urban electric power professional pipeline and comprehensive pipeline

Abstract

The invention discloses an urban electric power professional pipeline and comprehensive pipeline-oriented spatial data matching method, which comprises the following steps of: analyzing the difference between urban comprehensive pipeline spatial data and professional pipeline spatial data, and carrying out data preprocessing on the pipeline data; generating a power pipe network skeleton line by considering the structural characteristics of the power pipe network skeleton line and the structural characteristics of the power pipe network; feature factors are selected, two types of pipeline skeleton lines are matched, and a power pipe network key structure point matching result is generated according to a skeleton line matching result; and selecting a similarity factor, calculating a pipe point matching similarity result, generating a pipe point matching result set by manually setting a threshold value, and finally completing pipeline matching according to the pipe point matching result. In order to solve the problem of'two data and repeated detection 'in underground pipelines, on the basis of analyzing the overall morphological structure characteristics of a power pipe network, the GIS vector spatial data matching method is utilized to complete matching of comprehensive power pipeline spatial data and professional power pipeline spatial data.

Description

technical field [0001] The invention belongs to the technical field of geographic information systems, and in particular relates to a spatial data matching method for urban power professional pipelines and comprehensive pipelines. Background technique [0002] Urban underground pipelines are one of the important material bases for urban development. They are responsible for transmitting information and transporting energy. They are the material bases for the survival and development of cities. They are called the "lifeline" and "bloodline" of cities. With the rapid development of modernization and "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...

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
