Modeling existing buildings three-dimensional (3D) using unmanned aerial vehicles: A study case in Binus Syahdan Campus Building

Developments in the field of photogrammetric technology using UAV (Unmanned Aerial Vehicle) make it easier to represent mapping results quickly and accurately. Along with the growing need for spatial use, both horizontally and vertically, have implications for the need of accurate spatial data both in two-dimensional (2D) or three-dimensional (3D) space. 3D visualization and modeling is a representation of the surface of the earth with the aim of supplying the appearance of the earth along with the whole above it more realistic and able to provide a broader perspective compared to 2D visualization or conventional maps. In this study, the drone-based UAV was used, namely DJI Mavic Air to collect geometric data on the Syahdan campus. The digital data that has been recorded by the UAV is then processed into three-dimensional modeling using DroneDeploy software. DroneDeploy software is cloud-based and is generally used for aerial mapping, in this study it is used in making 3D modeling because of its efficient. The elevation data at each building point measured using a drone-based UAV are compared with the as-built drawing of the Syahdan Campus, Binus. The root mean square value of the comparison of elevation distance between 3D model and as built drawing is 0.47 meters.
