Accurate on-time geo-information for disaster management and disaster prevention by precise airborne lidar scanning

Abstract

TopoSys GmbH manufactures and operates high-end fiber based airborne Lidar sensor systems which also include a for spectral optical line scanner. Airborne Lidar sensor systems are capable of playing a dominant role at data acquisition for disaster prevention and disaster management, especially the systems of TopoSys which focus on high precise, high dense mapping. Obviously disaster management could only be as good as the information it has got for its decisions. The data need to be on-time, precise, accurate and actual. The presentation shows concepts how to use Lidar sensor systems for on-time data acquisition. Basic products like high resolution RGB and CIR ortho images or elevation models and their usage for disaster management are being presented as well as derived products like shore line or vectorized flooded areas. The sketch of a disaster data acquisition plan (DDAP) is shown which integrates real-time data acquisition e.g. for the use for police, rescue teams or relief organizations and post processed data for e.g. insurances, services or activities for prevention. In addition to concepts for data acquisition for disaster management, ideas for data acquisition for disaster prevention like regular survey and change monitoring of critical areas are being presented. A view on the future is also given how airborne Lidar sensor systems will be developed further to better serve the needs of efficient autonomous on-time data collection. © 2005 Springer-Verlag Berlin Heidelberg.
