Before revision: Pedometric mapping methods Pedometric mapping methods differ based on the soil survey data processing steps: Sampling Data screening Preprocessing of soil covariates Fitting of geostatistical model Spatial prediction Cross-validation / accuracy assessment Visualization of outputs One of the main theoretical basis for pedometric mapping is the universal model of soil variation: where is the deterministic part of soil variation, is the stochastic, spatially auto-correlated part of variation, and is the remaining residual variation (measurement errors, short-range variability etc.)
