The SWIR/NIR/RED false-color composite (left) makes vegetation obvious: Irrigated farmland is bright green; woodland darker green; bare fields tan; the city of Dubbo blue-gray; and water dark blue. The midwave infrared band (middle) responds to both temperature and surface type. Warmer is brighter, but infrastructure, buildings, and crop patterns still show through. The longwave infrared (right) is a temperature map. In this daytime image, water and vegetation are the coolest surfaces and appear dark; bare fields and pavement are warmest and appear brighter.
