Spectral reflectance of hydrophytes

Remote Sensing of Environment 11(1): 27-36
Spectral reflectance of hydrophytes
Identification of hydrophytes will improve the delineation and classification of wetlands on remotely sensed imagery. Spectral reflectance measurements of 10 spp. of hydrophytes [Typha angustifolia (narrow-leaved cattail), Scirpus validus (soft-stem bulrush), S. fluviatilis (river bulrush), Phragmites communis (common reed), Alisma plantago-aquatica (water plantain), Scolochloa festucacea (whitetop), Sparganium eurycarpum (bur reed), Hordeum jubatum (foxtail barley), Polygonum coccineum (water smartweed) and Spartina pectinata (prairie cordgrass)] were made with an Exotech radiometer during 3 phenological stages, flowering and early seed, senescent, and early emergent. Reflectance data were analyzed to determine significant (P < 0.5) differences between species in each of 4 spectral regions during each phenological stage. Eight species had significantly (P < 0.05) different reflectances during the flower and early seed stage. Among the 10 spp., only 1 could not be spectrally isolated during at least 1 phenological stage. Apparently, films sensitive to both visible and IR spectra (e.g., ektachrome IR) should enable recognition of different species of hydrophytes.
