Global 1-km Gridded Thickness of Soil, Regolith, and Sedimentary Deposit Layers

Data Set Overview

Data setGlobal 1-km Gridded Thickness of Soil, Regolith, and Sedimentary Deposit Layers
Release date2016-02-03
ProjectSoil Collections
Time Period1900-01-01 to 2015-12-31


This data set provides high-resolution estimates of the thickness of the permeable layers above bedrock (soil, regolith, and sedimentary deposits) within a global 30-arcsecond (~1-km) grid using the best available data for topography, climate, and geology as input. These data are modeled to represent estimated thicknesses by landform type for the geological present.
