Abstract With the smart city concept, the requirement for visual presentation has increased to help decision-makers or users to properly organize, plan, and simulate large-scale and complex smart city scenarios. Therefore, the requirement of three-dimensional (3D) modeling of any structure for smart city applications has emerged and the concept of digital twin has gained importance. Unmanned Aerial Vehicle (UAV) photogrammetry method is often preferred to create a 3D model because it provides time and cost savings. This study aims to produce a high-quality 3D model of a library building located at the Gebze Technical University. For this aim, GeoMax Zoom25 and DJI Phantom 3 Advance were employed for conservative measures and acquiring UAV image process respectively. 368 images were taken and the acquired images were processed in Agisoft Metashape software. After completing the processes, the total root mean square error was calculated as 1.28 cm. The indoor solid model of the building was also produced employing conventional surveying techniques. As a result of the study, it was found that a high-accurate 3D model for integration into smart city applications can be produced based on the UAV photogrammetric method. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.
