Abstract

The AA. present a novel, automatic method for water surface classification and delineation by combining the geometrical and signal intensity information provided by airborne laser scanning (ALS). The reflection characteristics of water surfaces in the near-infrared wavelength (1064 nm) of the ALS system along with the surface roughness information provide the basis for the differentiation between water and land areas. The water-land-boundary is defined by the central contour line of the transition zone between water and land points. The AA. demonstrate that the proposed workflow succeeds for a regulated river (Inn, Austria) with smooth water surface as well as for a pro-glacial braided river (Hintereisfernerbach, Austria).
