Geospatial Survey Analysis for 3D Field and Building Mapping using DJI Drone and Intelligent Flight Battery

Abstract

Geospatial industry undergoes revolution for every few years. The industry used total stations, GPS, and robotics for the past mapping method. Now, professionals around the world are using drones for mapping which boast quick data collection times, excellent accuracy, and safe operator experience. However, the method for making a 3D map of field and buildings are different. For making a 3D model of buildings, drone must collect the data of buildings by orbiting each of the building. Surveyor will need more time and effort to make a 3D map of buildings than field in the same quality. Therefore, professionals have to make an effective plan to survey different kinds of region. For this research, we used DJI Phantom 4 Pro which has the intelligent Lithium Ion Polymer Battery with the capacity of 5350 mAh. Using the drone, we used different kinds of grid plans to collect map data of regions with buildings and a sport field in Institut Teknologi Bandung, Indonesia. A 3D modelling software is being used to construct an orthophoto and 3D model of the surveyed region which results error data of 3-5 m. According to this research, we can survey about 111.180 m2 area with 0.045m/px resolution using only one battery by the overlap image of 80% We believe these flight plans can inspire researcher and professionals of geospatial to develop other plans for bigger survey application.
