The version 3.0 annual 100m land cover classes were mapped with high temporal stability across years and an overall mapping accuracy just over 80% (80.6% in 2015, 80.3% in 2019), when compared to the 28K independent validation points. The statistical validation meets the CEOS Land Product Validation Stage 4 requirements. The updated 2019 classification map shows slightly higher accuracy than the previous version and improvements in characterizing forest, cropland and permanent water classes. Spatial accuracy assessment for three aggregated classes (forest, crops and natural vegetation) against a set of over 200K independent validation points revealed a high level of accuracy in different regions of the world and highlighted areas for further improvement.
