Accurate Digital Terrain Models (DTMs) are inevitable inputs for mapping and analyzing areas subject to natural hazards. Topographic airborne laser scanning has become an established technique to characterize the Earth's surface: lidar provides 3D point clouds allowing for a fine reconstruction of the topography while preserving high frequencies of the relief. For flood hazard modeling, the key step,...
Accurate Digital Terrain Models (DTM) are inevitable inputs for mapping areas subject to natural hazards. Topographic lidar scanning has become an established technique to characterize the Earth surface: and reconstruct the topography. For flood hazard modeling in coastal areas, the key step before terrain modeling is the discrimination of land and water surfaces within the delivered point clouds...
