%description
Creating spatially or environmentally separated folds for cross-validation
to provide a robust error estimation in spatially structured environments;
Investigating and visualising the effective range of spatial
autocorrelation in continuous raster covariates to find an initial
realistic distance band to separate training and testing datasets
spatially described in Valavi, R. et al. (2019)
