Abstract

The invention discloses a spatial data matching method for urban gas professional pipelines and comprehensive pipelines. The method comprises the following steps: analyzing the distribution characteristics of an urban underground gas pipeline network through a layering method, and performing data preprocessing on pipeline data; considering the Stroke characteristics of the gas network and the structural characteristics of the gas network, generating the skeleton lines of the gas network; according to the matching result of skeleton line, generating the matching result of key structure points of the gas pipeline network; selecting the similarity factor, calculating the pipe matching similarity results, generating a pipe matching result set through manual threshold setting, and according tothe pipe matching results, the finally completing pipeline matching. Aiming at the problem of two data, repeated detection existing in the urban underground pipeline, on the basis of analyzing the overall shape and structure characteristics of the gas pipeline network, the method of the invention utilizes the GIS vector spatial data matching method to complete the matching of the comprehensive gaspipeline spatial data and the professional gas pipeline spatial data.

Description

technical field [0001] The invention relates to the field of geographic information, in particular to a spatial data matching method for professional urban gas 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 professional underground ...
