Abstract
The obtaining of a Digital Surface models (DSMs) at different scales and levels before the appearance of Unmanned Aerial Vehicles (UAV) was very rare or impossible. UAV’s with advanced photogrammetry software can produce high-resolution Digital Surface Models at multiscale levels with several spatial resolutions. In this paper we tested the Arc–Chord Ratio (ACR) method decouples rugosity from the slope at multiscale DSM generated from six different UAV flight altitudes of 20, 40, 60, 120, 240 and 360 meters for the study and analysis of the surface to planar areas changes with spatial resolutions.
