지하시설물 정확도 향상을 위한 Data Life Cycle 상의 개선방안 도출 - 영천시, 경주시, 구리시의 사례를 중심으로 -

Abstract

The purpose of this study is to present measures to improve the data improvement plan, generation, construction, management, storage, and utilization stage in consideration of in-depth interviews with local governments and data characteristics of underground facilities. The results derived are that first, the project promotion plan at the planning stage needs to review the appropriateness of the budget design of the underground facility accuracy improvement project of local governments and review the appropriateness of the selection of the project target area. Second, the project promotion plan at the creation and construction stage needs to extract areas that are feared to degrade DB accuracy, check the consistency of field drawings and location editing data, and check major errors in structured editing data performance. Third, the project promotion plan at the management stage requires management and inspection of non-detection sections, adequacy check of the cause of non-detection, performance check in areas where water, sewage, power, and communication facilities are concentrated, and attribute and logical error check. Fourth, the project promotion plan at the storage and utilization stage needs to be checked for compliance with table definitions by local governments UIS and for the appropriateness of data loading. It is judged that the derived project promotion plan can secure the quality of performance and improve the reliability of performance in terms of data. In addition, from a national perspective, it is judged that it is possible to reduce the national budget and secure consistency in administrative work.
