Paper Abstract
The suitability of visible spectral response of vegetation for remote sensing has been investigated with field and
laboratory studies on canopy and chloroplastidial pigments, respectively. To simulate band-spectral and hyperspectral
sensing, measurements were taken both in wavebands and with fine resolution of wavelength. Vegetation species and
maturity stages were distinguished with average reflectance and characteristic absorption features. The methodology
was tried on both land vegetation, viz. jute canopy of West Bengal and marine plant, viz. green algae of the eastern coast
of India. The absorbance variation within visible wavelength range was observed with both mixed chlorophyll solution
and solutions of chromatographically separated pigments. The different characteristic absorption peaks were identified,
which were quite different for higher plants and algae. The gradual changes in spectral response of leaf pigments with
senescence in a common higher plant were systematically investigated with both original leaf extracts and artificial
mixtures of fresh and decomposed chlorophyll solutions at different ratios. Mathematical models were put forward for
both average and hyperspectral absorption features to track the experimental plots and estimate absorption at different
wavelengths.
