The British Isles seen from space. This is a mosaic of 52 false-colour images made by the Landsat satellites in 1985. The colours represent different surface cover: reds indicate pasture, orange/brown shows arable land, blue/grey indicates urban areas. Light blue indicates coastal sands and silts. Scotland is dominated by dark olive green, denoting mixed moorland and extensive coniferous forest cover. Pale blue/green indicates moist vegetative cover and alkaline soils, seen especially in granitic formations in Wales, the Lake District and the west coast of Ireland.
