SELECTION OF A SEVENTH SPECTRAL BAND FOR THE LANDSAT-D THEMATIC MAPPER

摘要

A study was carried out to develop recommendations for a 7th spectral band on the Landsat-D Thematic Mapper (TM). Beginning with a survey of remote sensing specialists the technical concepts supporting proposed applications were examined to identify ca idate spectral bands. Two candidate bands in the near-1K (0.70-0.74 μm and a 1.2 urn centered ban.) were investigated for agricultural applications arid two candidate bands (2.2 lira centered band and a 2nd thermal band) were investigated for geological applications. Each of these candidate bands were examined in terms of the feasibility of gathering high quality imagery from space while taking into account solar illumination. atmospheric attenuation and the signal/noise ratio achievable within the TM sensor constraints.
