Set data Modifikasi Manusia global (gHM) memberikan ukuran kumulatif modifikasi manusia terhadap lahan terestrial secara global pada resolusi 1 kilometer persegi. Nilai gHM
berkisar dari 0,0-1,0 dan dihitung dengan memperkirakan proporsi lokasi (piksel) tertentu yang dimodifikasi, perkiraan intensitas modifikasi yang terkait dengan jenis modifikasi manusia atau "pemicu stres" tertentu.
5 tekanan antropogenik utama sekitar tahun 2016 dipetakan menggunakan 13 set data individual:
permukiman manusia (kepadatan penduduk, area terbangun)
pertanian (lahan tanaman, peternakan)
transportasi (jalan utama, jalan kecil, dan jalan dua jalur; rel kereta api)
pertambangan dan produksi energi
infrastruktur listrik (saluran listrik, lampu malam)
Lihat makalah ini untuk mengetahui detail metodologi tambahan.
Aset ini diproyeksikan ulang ke WGS84 untuk digunakan di Earth Engine.
