“…Given that many of the volcanoes analyzed in CCVR were barely 20 m high, it was necessary to automatically generate contour lines with an equidistance of 1 m from DEMs (5-m pixel resolution) in geographic information systems (GIS) (ArcMap 10.8, ESRI license for University of Castilla-La Mancha) (Figure 3). Using contour lines with an equidistance of 1 m, the morphometric measurements are much more accurate than in the traditional literature, which used maps at scales of 1:25,000 and 1:50,000 [7,12,15,24,27,33,74]. Therefore, in the preparation of the geomorphological maps of each volcano, we worked with a scale of 1:5000, which also offers much more precision when delimiting the morphology of the cone (and lava flows), and calculating parameters such as height, surface area, cone and crater diameter, etc., as has been done in other recent studies [19,20,41,42,75].…”
