Application of Digital Photogrammetry from UAV Integrated by Terrestrial Laser Scanning to Disaster Management Brcko Flooding Case Study (Bosnia Herzegovina)

The recent development of the unmanned aircraft (UAV) in the civil sector has generated a strong interest in the aerial survey industry, especially in sectors where costs and speed of use play a key role. In May 2014, in Brcko region, Bosnia & Herzegovina, torrential rains and flooding of rivers and torrents occurred, thus activating hundreds of landslides. In this paper, the methodology used for the survey of two landslides, identified in the Brcko area, and the obtained results have been described. Photogrammetry from UAV and laser scanning surveys were carried out in June 2015 in the framework of the international no profit Project “Assessment of flood-damaged infrastructures in Bosnia & Herzegovina and Serbia”, led and funded by SEG (Society of Exploration Geophysicists) and AGES (Association of Geophysicists and Environmentalists of Serbia). The purpose of this work is to integrate laser scanner data with the ones generated by aerial photogrammetry from UAV, in order to produce detailed maps that can be used by geophysicists to optimize their analysis.
