Most infrared aerial documentation involves the creation of vertical infrared aerials. Combined with orthorecitification techniques, comprehensive infrared aerial maps can be created which can be invaluable both for planning and monitoring purposes. In this infrared aerial photo, the red shades indicate vegetation (and the tone of red indicates how well it is growing); tan or green indicates dead vegetation; green, blue or white can indicate ground areas, depending on the moisture and composition of the soil.http://www.aerialarchives.com/imagedb/IR0010154f.jpg
