%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 and point samples to find
an initial realistic distance band to separate training and testing
datasets spatially described in Valavi, R. et al. (2019)
