Глобальный набор данных об изменениях, внесённых человеком (gHM), предоставляет кумулятивную оценку антропогенного воздействия на земную поверхность с разрешением 1 квадратный километр. Значения gHM варьируются от 0,0 до 1,0 и рассчитываются путём оценки доли изменённой площади заданного участка (пикселя), а также предполагаемой интенсивности изменений, связанных с определённым типом антропогенного воздействия или «стрессовым фактором». 5 основных антропогенных стрессовых факторов, наблюдавшихся около 2016 года, были картированы с использованием 13 отдельных наборов данных:
населенные пункты (плотность населения, застроенные территории)
сельское хозяйство (пахотные земли, животноводство)
транспорт (магистральные, второстепенные и двухпутные дороги; железные дороги)
