THE USE OF UNMANNED AERIAL VEHICLES (UAV) FOR RECONSTRUCTION OF TOPOGRAPHY AND BATHYMETRY MAPS: CONSIDERATION FOR CIVIL CONSTRUCTION AGAINST COASTAL ADAPTATION DUE TO CLIMATE CHANGING

Abstract

The global sea level rise is rapidly increased as the result of climate change which indicated by the expansion of marine heat and ice melting. It was identified as one of the most contributing factors, which threatens coastal communities, even national economy of a country. The combination of groundwater flooding and coastal flood was reported to make a total loss of at least 5 billion rupiahs with respect to crop failure of tons of seaweed as well as fish lost. The aim of this research is to construct a topographic and bathymetric map using Unmanned Aerial Vehicles (UAV)/drone series DJI Phantom 3 Advanced. The UAV is used in companion with other instruments, such as total station and geodetic station. The UAV is used mainly to take aerial images, which is further processed to obtain contour maps. The results indicate that the contour maps are accurate and can be used to help in making appropriate decision to the global climate change.
