Recently, the use of high-dimensional spatial information, such as a 3D reality model, which is built on the basis of unmanned aerial vehicles (UAVs), has become active in various industries, including the construction sector. To overcome the limitations of the current direct field survey and 2D-image-based surface utilization and the deterioration of work efficiency in the planning of urban development, in this study, we aim to verify the effectiveness of the 3D model using UAV-based aerial photography. For this purpose, six evaluation factors, namely, presence, spatial ability, conceptual understanding, aesthetics, work efficiency, and reliability, were set before and after the application of the 3D reality model, and a t-test was conducted. As a result, compared with the current 2D method, the survey method by applying the 3D method showed an average preference of 90.6%. In addition, as a result of the t-test to confirm the difference in utility between the current statuses of obstructions, significant differences between groups were confirmed in all six utility evaluation factors. As a result, the applicability and effectiveness of the 3D method according to the application of the 3D reality model could be demonstrated in terms of spatial ability, work efficiency, and reliability.
