The Modular Optoelectronic Multispectral Scanner (MOMS), a CCD type sensor, was flown on two Shuttle missions, STS-7 and STS-11, for experimental purpose. Two MOMS scenes from STS-11 mission were given to the Earthnet Programme Office, European Space Agency for image quality analysis. However, the Thematic Mapper (TM) data from Landsat 5 which represent the state-of-the-art of current remote sensing technology are the only available auxiliary data. Based on some primitive analyses using the TM data as reference, we can conclude as follows: 1) The registration accuracy between the two MOMS spectral bands is good. However, the algorithm for the radiometric calibration of MOMS detectors must be improved to remove the striping pattern caused by the inappropriate adjustment of radiometric values. 2) The projected ground pixel size of 20 x 20m was degraded by some unknown factors and the actual resolution of the MOMS data is much larger than the projected 20m ground size. For the time being, the geoscientific applications of the MOMS data are rather limited.
