ANALYSIS OF SIGNIFICANCE WITHIN CROP-SPECTRA-A Comparison Study of Different Multispectral Scanners

摘要

In order to study the spectral signatures of vegetation canopies, reflectance data of 11 crops was gathered during the growing season of 1973 using the double beam type spectrometer of NEARS. Using the obtained spectra, it was possible to determine for each crop or group of crops the pant of the spectrum which is most significant. From this knowledge the use of the channels of different multispectral scanners is concluded in relation to the relative information-contents of the channels. This information-summary leads to a quick classification, resulting in a comparison of the multispectral scanners.
