Digital soil suitability map of Switzerland - Permeability
This API provides access to part of the digital soil suitability map of Switzerland, focusing on soil permeability. Permeability values are derived from saturated soil core samples analyzed in the laboratory, with field observations used to relate precipitation, permeability and morphological features. The dataset evaluates the least permeable soil horizon within the top 50 cm of soil. It is published by the Swiss Confederation, likely via the Federal Office for Agriculture (BLW), and covers the national territory of Switzerland, supporting soil suitability and land-use assessment applications.Permeability is measured using saturated soil core samples in the laboratory. Observations in the field highlighted a relationship between precipitation, permeability and morphological features. The least permeable soil horizon of the top 50 cm was evaluated.
