Evaluation of LANDSAT MSS Data for Sugarcane Field Estimation

摘要

LANDSAT data were used to correlate with LAI, green biomass, percent ground cover, plant population, chlorophyll concentration and plant height for rangeland pasture, wheat, and soybeans. Multitemporal spectral information of sugarcane obtained during the crop year 1982 to 1983 were correlated with cane production and the possibility of using LANDSAT data for yield estimation was evaluated. Sun elevations of the eight LANDSAT data dates were corrected to 44 deg and the digital counts of the 24 sugarcane fields were acquired using an interactive image analysis system for each MSS channel. Correlation analyses were applied to cane yields and vegetation indices (i.e., D57, R75, TVI and PVI) that were derived from single or multidate LANDSAT spectral data. Significant correlation coefficients were found, however, amplitudes of the correlation coefficients were not high enough for a direct application on sugarcane yield estimation.
