How deep soil and loose rock go (global, 1 km)
What it measures. Estimates how thick the loose, permeable material above solid bedrock is, that is, the combined depth of soil, regolith (weathered rock), and sediment, on a roughly one-kilometer worldwide grid.
How it's made. Modeled by combining the best available data on terrain, climate, and geology, organized by landform type, rather than measured directly by a single sensor.
How & where you'd use it. Useful for groundwater and hydrology studies, landscape and erosion research, and Earth-system models that need to know how much loose ground sits on top of rock.

Official description
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.
