These are several convenience datasets that make it easier to plot and analyze the anthromes data. They primarily include lookup tables to easily translate between numeric and character representations of anthromes, biomes, and other data, as well as color ramps for easy plotting. The biome data are derived from the 15-class potential natural vegetation dataset of Ramankutty, N. and Foley, J.A., 1999. Estimating historical changes in global land cover: Croplands from 1700 to 1992. Global biogeochemical cycles, 13(4), pp.997-1027, along with a simplification using only 9 classes.
