USGS JECAM Canada South Nation

Joint Experiment for Crop Assessment and Monitoring

The overarching goal of JECAM is to reach a convergence of approaches, develop monitoring and reporting protocols and best practices for a variety of global agricultural systems. JECAM will enable the global agricultural monitoring community to compare results based on disparate sources of data, using various methods, over a variety of global cropping systems. It is intended that the JECAM experiments will facilitate international standards for data products and reporting, eventually supporting the development of a global system of systems for agricultural crop assessment and monitoring. The JECAM initiative is developed in the framework of GEO Global Agricultural Monitoring (GEOSS Task AG0703 a) and Agricultural Risk Management (GEOSS Task AG0703 b).

JECAM（作物评估与监测联合实验）旨在实现多种全球农业系统监测与报告协议及最佳实践的统一与优化。该实验旨在通过多种方法，对全球多样化的农作物系统进行数据来源的对比分析，从而促进国际数据产品及报告标准的形成，并最终支持全球农业作物评估与监测系统的构建。JECAM项目是在地球观测系统全球农业监测（GEOSS任务AG0703 a）和农业风险管理（GEOSS任务AG0703 b）框架下开发的。
