DIGITAL SLOPE MAPPING USING UNMANNED AERIAL VEHICLE (UAV)

This paper discusses the applications of unmanned aerial vehicle (UAV) for slope mapping and its important parameters including perimeter, area and volume of four selected areas of slope A, slope B, slope C and slope D. Modern UAV is able to capture high quality images and convert them into a natural mapping output extracted from the commercial software such as Digital Surface Model (DSM) and Digital Orthophoto. Two locations in Kuantan Pahang were selected at Sungai Lembing and Politeknik Sultan Ahmad Shah ‘POLISAS’ for slope mapping analysis. The main interest of this study is to measure the perimeter, area and volume of selected study areas using a commercial software. In addition, this modern method of mapping was proven to be more effective than the traditional method in terms of less cost, can generate huge data entry in a brief time, low man power and no potential risk of hazardous effect to man. In conclusion, modern technology of UAV is an efficient way of mapping for geotechnical engineering. Slope mapping help researchers and engineers to obtain slope measurement within a short period of time compared to previous traditional method.
