In this study, we establish a 3D data model of underground utilities that applies international spatial information standards correspondingly, and we design a data model on the basis of this model to improve the systematic construction and management of underground utilities information and its accuracy and quality. The detailed research procedure is as follows. First, through a review of the existing system status and preceding studies, the necessity of this study and how it is differentiated from existing studies are derived by reviewing domestic and overseas research trends related to underground utilities and the current status of existing underground information systems. Second, considering the establishment of a 3D data model, we selected a reference model suitable for expressing underground utilities information by comparing and reviewing international standards, and this model was used as the basis of the data model. Lastly, regarding the design of a data model for underground utilities, a 3D data model of an underground utility based on international standards was designed using a Unified Modeling Language (UML) diagram based on previously defined contents. On the basis of these results, it is expected that the 3D data model for underground utilities with improved consistency with the real world for both above-ground and underground spaces will improve the accuracy and utilization of existing underground information.Corresponding author: Jong Wook Ahn
