Special Reflectance of Hydrophytes
Identification of hydrophytes will improve the delineation and classification of wetlands on remotely sensed imagery. Spectral reflectance measurements of 10 species of hydrophytes were made with an Exotach radiometer during three phenological stages, flowering and early seed, senescence, and early …
