Method for generating spectral datasets, apparatus for generating spectral datasets, program for generating spectral datasets, and recording medium.

Abstract

This technology generates a spectral dataset that can be applied to any of the many formulas used to calculate vegetation indices and enables accurate calculations. [Solution] The spectral dataset generation method (S1) includes an acquisition step (S11) of acquiring multiple spectral data sets, each containing wavelength and brightness data of reflected sunlight from the ground surface where crops grow, with varying exposure times; a determination step (S12) of determining, for each spectral data set, whether there is a proportional relationship between the exposure time and the brightness data, for each wavelength; and a generation step (S13) of extracting and combining spectral data sets within the range of exposure times determined to have a proportional relationship from the multiple spectral data sets, for each wavelength, to generate a spectral dataset optimized for each wavelength.
