The DEMIX ‘wine contest’ is a novel framework for a practical approach to inter-compare a range of candidate digital elevation models (DEMs) based on pre-defined criteria and a statistically sound ranking approach, known as the randomized complete block design (RCBD). The application of the `wine contest' to six 1 arc-second global DEMs, considering a wide set of study sites, covering different morphological and landcover settings, highlights the potentialities of the approach. Results confirmed significant superiority of COPDEM and FABDEM over ALOS AW3D30, NASADEM, SRTM and ASTER GDEM. |
