ERTS-1 Multispectral Scanner Data is received from the satellite by NASA, processed, and delivered to users recorded on computer compatible tape and in photographic form. The computer tape form of the data is calibrated and line length adjusted by NASA but no geometric corrections are applied. The system-corrected photographic products are corrected for many geometric distortions including earth rotation effects in addition to the above two corrections. Also, these images are rescaled so that the horizontal and vertical scales are the same. Thus, the digital form of the MSS data contains many geometric distortions and users of this data are faced with the problem of compensating for these errors.
