  1. For each definition, the value between brackets indicates the resolution of the elevation raster in arc minutes and seconds. The GMBA Definition v2.0 layer corresponds to the output of step iii after the application of the majority filter. The columns are not ordered by year of publication of the mountain delineations but increasingly relative to the cover percentage of the GMBA Definition v2.0.
