Relating Thematic Mapper Bands TM3, TM4, and TM5 to Agronomic Variables for Corn, Cotton, Sugarbeet, Soybean, Sorghum, Sunflower and Tobacco

摘要

Red, photographic infrared, near infrared spectral data of corn, cotton, soybeans, sugar beets, sorghum, sunflowers and tobacco were collected throughout the entire growing season by using a three band handheld radiometer. Different radiance patterns were found among these crops based on their morphology, green biomass duration and leaf size. Results show near infrared radiance is a good indicator of water content in plant tissue under small scale experimental conditions.
