false colour A term used in remote sensing techniques to describe the display of data collected in a number of different wavelengths, usually longer or shorter than those perceptible to the naked eye. Typical false-colour images include infrared data, which are often displayed as visible red. Thus green vegetation, which is highly reflective in the infrared, typically appears red on a false-colour image.
