The Global Pedogenon Map: Combining and Spatialising the Factors of Soil Formation

Description

The global pedogenon map classifies soil units based on similarities in their formation processes while excluding anthropogenic effects, at a high spatial resolution of 90 meters in the Equator. 

This repository contains data from a scientific work that was published in Geoderma (Francos et al., 2025a), presented in the Digital Soil Mapping & GlobalSoilMap conference in Bengalore, India, 2025 (Francos et al., 2025b), and in the Soils for Our Future 2025 Conference in Winnipeg, Canada (Francos et al., 2025c):

• The global pedogenon map in 90-meters resolution: GPM_mosaic_17062025.tif
• The centroids of the pedogenon classes: RGB_CENTROIDS_04062025.csv
• Sampling points after data processing and before classification: POINTS_04062025.csv

Format:

• Raster map in GeoTIFF format (*.tif).
