Though our planet is characterised by unique, fascinating landscapes, large swathes of them remain mostly hidden from us. Gigantic mountain ranges, deep forests and endless deserts reveal themselves in all their incredible detail only when viewed from above. Drones, helicopters and balloons provide us with spectacular views: Glaciers in the European Alps, tropical rainforests in Borneo, rugged karst mountains in China, vast grassy plains in Mongolia, expansive forests in Lapland and enormous river systems like the Okavango and the Nile.
