What are spectral matching techniques (SMTs)?
Matching the spectra of a class with spectra of a known or target class. The target spectra can be obtained from ideal locations (e.g., areas where we absolutely are sure it is irrigated) . In absence of ideal locations, we can group spectra of many classes that have nearly same spectral characteristics in time-series data. Such comparisons are made using quantitative or qualitative approaches as explained in detail in SMT methods.
