Maps of total and active CaCO3 content (0-30 cm) of the soils of Emilia-Romagna (NE Italy)

The two datasets contain the maps of total and active limestone (reference depth 0-30 cm) for the soils of Emilia-Romgna (NE Italy). The maps are in raster format (GEOTIF) and have a spatial resolution of 100 m; the Rs system is EPSG 7791. For both total and active limestone, maps of estimation uncertainty are provided; uncertainty classes (low, medium and high) were based on the width of the interquartile ranges (P75-P25) assessed via Digital Soil Mapping (DSM) via Quantile Random Forest. A raster map of the difference between total and active CaCO3 is also provided (in CALATT_0_30.zip).
