Lasers can be used to produce images such as maps. A scanning process builds up an image on to light-sensitive paper. Originally, the information is generated by a satellite which detects the natural infra-red radiation from the surface of the Earth. These data are then re-transmitted to a receiver back on earth. More detailed images of this type are used for surveys of land use, and it is sometimes possible to distinguish between different crops.
