Annual mapping of soil organic carbon stock in Brazil 1985-2021 (beta collection). Training field soil datahttps://doi.org/10.60502/SoilData/XDBQ4UMapBiomasSoilData2023-08-042024-12-14T13:40:23ZCollection of 9649 points containing field data to the train regression models used to map the soil organic carbon stock in Brazil. The field data includes spatial and temporal coordinates, and the soil organic carbon stock at the point support for up to 30 cm depth.<b>Detailed description</b>. The source data was obtained from the Brazilian soil data repository SoilData (<a href="https://soildata.mapbiomas.org">https://soildata.mapbiomas.org</a>). A sum of 9649 data points coming from multiple datasets published before 2021 was processed. The training field data includes spatial and temporal coordinates, and the soil organic carbon stock at the point support for up to 30 cm depth.
