Planning and Execution of a Photographic Mission over a Wheat Producing Region in Rio Grande Do Sul, Brazil

摘要

A wheat survey program was completed with the execution of a photographic mission during the booting growth stage of wheat. Three 20 km. by 40 km. target areas in Rio Grande do Sul were flown after cost/time saving changes in aircraft, oxygen requirements, geometric parameters and base of operations. A WILD RC-10 metric camera with WRATTEN filter was used to expose color IR film to produce 1:20,000 scale transparencies and semicontrolled mosaics for hectareage estimations and data integration with hardware for CCT analyses.
