3D MODEL PROTOTYPE OF PALANGKA RAYA UNIVERSITY BASED ON GEOSPATIAL DATA USING DRONE PHOTOGRAMMERY

Abstract

Utilization of Drone Technology (Unmanned Aerial Vehicle/UAV) in the geospatial field has rapidly advanced in recent years, particularly in mapping and three-dimensional (3D) modeling. This study aims to explore and apply drone imagery technology in the creation of a 3D model (digital mock-up) of the environment at the University of Palangka Raya campus, serving as an accurate and informative spatial visual representation. Data collection was conducted through aerial image acquisition using a drone equipped with a high-resolution camera, with systematically planned flight parameters to ensure adequate coverage and overlap. The data processing was carried out using Structure from Motion (SfM)-based photogrammetry software, which included stages such as image orientation, point cloud reconstruction, mesh model creation, and texturing. The resulting 3D model was then evaluated both visually and geometrically to assess its spatial accuracy and completeness. The results show that 3D modeling using drone imagery is capable of representing the shapes and structures of buildings, vegetation, and other campus environmental features with a high level of detail. The spatial accuracy of the model also falls within acceptable tolerance limits for visualization and site planning purposes. The significance of this research lies in the time and cost efficiency of the mapping process compared to conventional methods such as manual field surveying. Additionally, the 3D model holds great potential to support academic activities, campus development planning, asset preservation, and as an engaging medium for visual promotion. Thus, the integration of drone and photogrammetry technology can serve as an innovative solution for the development of modern and applicable geospatial information systems in higher education environments
