Description
Summary:In this study, we present a logical spatial data model according to the International Organization for Standardization (ISO) 19109 targeting nine types of underground utilities (wide-area water, water, sewage, heating, communication, electric power, gas, garbage, and oil) among underground information. To this end, we reviewed the integrated underground utility systems in Korea, the integrated underground spatial maps, and previous studies in South Korea and abroad. Subsequently, the design direction of the underground utility data model is constructed on the basis of the problems derived from the review of previous studies and current status. According to the design direction, the terminologies of underground utilities, classification systems, and topological association between objects are defined. The ISO and Open Geospatial Consortium (OGC) standards established as international standards are referenced to design applicable spatial data models suitable for Korea's underground space environment using Unified Modeling Language (UML) diagrams. The resulting design is expected to provide consistency to the underground utility data and play a role in the interoperability of domestic and foreign underground utility data.
