摘要:

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.

摘要:

The inflight calibration data of coastal zone colour scanner (CZCS) data for several scenes have been studied and it is shown that the calibration has changed with time. This variation cannot be neglected if one intends to extract quantitative information about suspended material in the sea from the CZCS data. This variation has been studied statistically and a set of correction formulae has been obtained for each of bands 1–4.

摘要:

Inconsistent or erroneous terminology can be a barrier to the dissemination of ideas and information. Eleven inconsistent or erroneous remote sensing terms are offered as a means of stimulating debate on this topic.

摘要:

An allegation that has been made that we have placed excessive weight on measurements of spectral ratios for winter wheat early in the season is refuted.
