Thematic Mapper radiometric characterization
Abstract
Characteristics of multispectral scanner systems that are desirable for radiometry are identified. Both 'macroscopic' and 'microscopic' studies of Landsat-4 Thematic Mapper digital image data are described which assess several of these characteristics. Included are the range and quantization of signal values, scan-angle effects, scan-direction effects, and level-shift noise characteristics. Despite good overall radiometric quality, some relatively low-amplitude artifacts were noted and correction procedures are recommended. Consideration of the use of stepwise linear system-response characteristics is recommended. The acquisition of a unique data set of coincident Landsat-4 and Landsat-5 data is noted; it was acquired before Landsat 5 reached its final orbit.
