Description

Download, project and (optionally) resample SoilGrids data for the area of your interest. SoilGrids is a global collection of gridded soil property data produced using machine learning at 250m resolution. Predictions are made at six standard depths (0-5, 5-15, 15-30, 30-60, 60-100, 100-200cm), except for organic carbon stocks, which provide one single value for the upper soil (0-30cm).
