US forests. The US Department of Agriculture’s National Forest Type Dataset shows the geographic distribution of the country’s “forest types” — defined as ”logical ecological groupings of species mixes.” (Examples include “deciduous oak woodland” and “subalpine fir.”) To estimate the extent of each forest type, the dataset’s developers combined satellite imagery with “nearly 100 other geospatial data layers, including elevation, slope, aspect, and ecoregions.” Related: The Washington Post has used the dataset to map fall foliage and forests where Christmas-y trees grow.
