LIDAXES (version 2) - Axes of concentration of runoff (vector)

APINational · BelgiumNo auth

This vector data layer represents the natural concentration axes of runoff water, which correspond to thalwegs, valleys and dry valleys, established on the basis of the MNT LiDAR 2013-2014. The mapping of the natural concentration axes of runoff (LiDAXES) highlights areas at risk of runoff floodin…
