Abstract A preliminary analysis of Thematic Mapper products, from scenes of part of Michigan and the Mississippi valley near the Arkansas-Missouri border is presented. Results show that the range of digital values for the visible bands in particular is very narrow relative to the available 255 digital counts. The visible bands in particular are very strongly correlated for the sub-scenes examined. Principal component analysis reveals the Thematic Mapper bands have an overall three dimensional structure. However, examination of individual cover categories reveals that most of the bands appear to have separate discriminatory value.
