Unmanned Aerial Vehicles (UAVs), commonly known as drones, have emerged as a transformative technology within urban management as an aerial photography tool that presents novel avenues for refining digital twin creation, fostering public engagement, and deepening comprehension of the built environment. This study examines the accuracy of 3D models produced through UAV photogrammetry in contrast to web-based 3D models. By doing so, it interprets the consequential impact of such variances on their adaptability across diverse urban and regional planning tasks. Discerning each approach's distinct merits and demerits, the research identifies optimal contexts for their respective deployment. In addition, the paper addresses the limitations intrinsic to UAV deployment in urban and regional planning. These insights pave the way for innovative avenues in 3D model construction that amplify public engagement and involvement, thereby cultivating a more inclusive and informed planning paradigm.
