    The paper deals with the problems of surface temperature mapping by infrared scanning. It is found that, for vegetation covered ground, circular scanning and inclined line scanning are preferable to the common method of line scanning with normal scan plane. For water surfaces circular scanning of polarized infrared radiation at the Brewster angle seems to be the optimum. Additional information is necessary for the identification of terrain for airborne scanning, and for the separation of clouds at different altitudes from satellites. It is shown that this can be resolved by convergent scanning and stereoscopic interpretation of the images. Those methods are practicable for line scanning as well as for circular scanning.
