The painting of Lake CarnegieThis multi-spectral Landsat Image of Western Australia’s Lake Car
The painting of Lake CarnegieThis multi-spectral Landsat Image of Western Australia’s Lake Carnegie looks like it could have been ripped from the walls of an art museum.Lake Carnegie is a closed, ephemeral lake. It only fills during particularly rainy years; during normal or dry years, the water evaporates, reducing it to a marsh or an almost dry saltpan.This is not how Lake Carnegie appears to the eye - it has been processed from data collected by the Landsat 7 spacecraft. In a multi-spectral image, the actual wavelengths of light measured have been changed, so that different types of light are moved onto the visible spectrum making it possible for our eyes to see them. Different colors reflect the different types of light reaching the spacecraft; green is tuned to show vegetation, red is tuned to show drier land, and the blues show sediment motion and flow paths within the lake itself.-JBBImage credit: http://www.nasa.gov/multimedia/imagegallery/image_feature_817.html -- source link
