UTILIZING CASSINI-HUYGENS INSTRUMENTS WE PROPOSE TO COMBINE THE SPATIAL INFORMATION FROM ITS RADAR WITH THE SPECTRAL INFORMATION AND TEMPORAL COVERAGE OF ITS VISUAL AND INFRARED MAPPING SPECTROMETER (VIMS) TO INVESTIGATE THE CORRELATION BETWEEN GEOMORPHOLOGIC AND COMPOSITIONAL SIGNATURES ON OF SATURN S MOON TITAN. WE WILL DETERMINE THE DEGREE OF COMPOSITIONAL SEPARABILITY OF RADAR DEFINED GEOMORPHOLOGIC UNITS USING THE ENTIRE SET OF VIMS OBSERVATIONS - A DATASET UNIQUELY SUITED TO STATISTICAL ANALYSIS. BY KNOWING THE SPATIAL UNITS A PRIORI FROM RADAR WE WILL CLUSTER THE DATA INTO PHYSICALLY SIGNIFICANT GROUPS TO TEST SPECIFIC GEOLOGIC HYPOTHESES
