Mapping of environmental variables often relies on map accuracy assessment through cross- validation with the data used for calibrating the underlying mapping model. When the data …
Several spatial and non‐spatial Cross‐Validation (CV) methods have been used to perform map validation when additional sampling for validation purposes is not possible, yet it is …

Spatial analyses are indispensable analytical tools in biogeography and macroecology. In a recent Guest Editorial, Hawkins (Journal of Biogeography, 2012, 39, 1–9) raised several …
Using machine learning and earth observation data to capture real-world variability in spatial predictive mapping depends on sample size, design, and spatial extent …
H Meyer, E Pebesma - Methods in Ecology and Evolution, 2021 - Wiley Online Library
Abstract Machine learning algorithms have become very popular for spatial mapping of the environment due to their ability to fit nonlinear and complex relationships. However, this …
While the application of machine-learning algorithms has been highly simplified in the last years due to their well-documented integration in commonly used statistical programming …
Abstract Machine learning algorithms find frequent application in spatial prediction of biotic and abiotic environmental variables. However, the characteristics of spatial data, especially …
The recent wave of published global maps of ecological variables has caused as much excitement as it has received criticism. Here we look into the data and methods mostly used …
