Spatial data matching method oriented to urban water supply professional pipelines and integrated pipelines

Abstract

The invention discloses a spatial data matching method oriented to urban water supply professional pipelines and integrated pipelines. The method comprises the following steps that: analyzing differences between urban water supply professional pipeline spatial data and integrated pipeline spatial data, and carrying out data preprocessing on the pipeline data; giving consideration to water supply pipeline network Stroke characteristics and water supply pipeline network structural characteristics to generate a water supply pipeline network skeleton line; selecting a characteristic factor, matching two categories of pipeline skeleton lines, and according to a skeleton line matching result, generating a water supply pipeline network key structural point matching result; and selecting a similarity factor, calculating a pipeline point matching similarity result, manually setting a threshold value to generate a pipeline point matching result set, and on the basis of pipeline point matching results, finally finishing pipeline matching. The method aims at the problems that "two pieces of data are repeatedly detected" in an urban underground pipeline, and utilizes a GIS (Geographic Information System) vector space data matching method to finish the matching of the professional water supply pipeline spatial data and integrated water supply pipeline spatial data on the basis of analyzing the integral morphological structure characteristics of the water supply pipeline network.

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
