摘要:
Two separate types of contamination by shadowing have been identified following an analysis of two Thematic Mapper scenes from the Arctic. The well-established effect of orographic shadowing is particularly important for cryospheric surfaces. Cirrus clouds, often very difficult to identify by automated techniques, also cast shadows which decrease the radiances detected from snow and ice surfaces. These effects are illustrated here in relation to snow mapping algorithms.
