Characterization of vegetation with combined Thematic Mapper (TM) and Shuttle Imaging Radar (SIR-B) image data

Based on TM and SIR-B image data for Fresno County, California, in October 1984, we found that the sensors proVIded quantitative information on the amounts of herbaceous and woody vegetation in a given field. Optical reflectance spectra responded primarily to green, foliar biomass, and L-band (23-cm) backscattering coefficients related pnmanly to standing, woody bIOmass. A simple progressive transformation of the concatenated spectra produced three continuous measures of biophysical condition~ F1, F2, and F3 • These indicated the percent ground cover, the green leafarea Index (or standing green bIOmass per umt area), and the woody biomass per unit area, respectively.
