Overall percent agreement between the four input datasets classification of (a) very low or (b) low human influence of the terrestrial surface of the world and classified by biome. ‘Full’ indicates all four datasets are in full agreement and all identify that cell as low (or very low) human influence, while ‘none’ indicates zero of the datasets identify that cell as low (or very low) human influence. ‘Majority’ reference areas where three out of the four, ‘Mixed’ two out of four and ‘Minority’ one out of four datasets identify that cell as low (or very low) human influence
