主 题：CropWatch crop monitoring remote sensing crop production
摘 要：Monitoring the production of main agricultural crops is important to predict and prepare for disruptions in food supply and fluctuations in global crop market ***’s global crop-monitoring system(CropWatch)uses remote sensing data combined with selected field data to determine key crop production indicators:crop acreage,yield and production,crop condition,cropping intensity,crop-planting proportion,total food availability,and the status and severity of *** are combined to analyze the balance between supply and demand for various food crops and if needed provide early warning about possible food *** data processing is highly automated and the resulting products provide new kinds of inputs for food security *** paper presents a comprehensive overview of CropWatch as a remote sensingbased system,describing its structure,components,and monitoring *** paper also presents examples of monitoring results and discusses the strengths and limitations of the CropWatch approach,as well as a comparison with other global crop-monitoring systems.
