Elevation Deviation Index. Elevation Deviation Index EDI (c) obtained as the ratio of elevation difference (a: 3DEP-1 - MERIT) and elevation standard deviation calculated using a moving window of 5 × 5 pixels of the 3DEP-1 (b). The coordinates reported in a are in Equi7 and expressed in metres. The study area refers to a zone of 18.4 × 20 km, which has a high level of forest cover, and is located in Alberta, Canada, close to Jasper National Park - image centre 118.25°W 53.29°N. The same area is used in the Fig. 4 to assess the geomorphometric variables.
