“…These covariates are organism activities, topographic conditions, spatially relative positions [18,20], land cover, and geological aspects [25]. Topographic covariates consist of slope, aspect, curvature, flow accumulation, wetness index, stream power index, landform classification, vegetation index, and soil map [26][27][28]. Peatland visual conditions also have a specific correlation to the existing peat depth, i.e., length and slope condition, land cover, vegetation, and the groundwater surface [14,29,30].…”
