Wu Bingfang, Meng Jihua, Li Qiangzi, Zhang Feifei, Du Xin, Yan Nana. Latest Development of “CropWatch”—An Global Crop Monitoring System with Remote Sensing[J]. Advances in Earth Science, 2010, 25(10): 1013-1022.

 “CropWatch”, developed and operated by Institute of Remote Sensing Applications (Chinese Academy of Sciences), is one of the three operational crop monitoring systems with remote sensing that can provide global-scale crop information. The system can provide information on crop yield, crop condition, crop acreage, crop production and agricultural drought, etc. The system has been developing since 1998. After 12 years′ improvement, it has been developed into a system that can provide independent, comprehensive and fast large scale crop information with advanced monitoring technology. A special issue on “CropWatch” was published by “Journal of Remote Sensing” in 2004 to summarize its methodology and development from 1998 to 2004. After that (20052009), “CropWatch” has made great improvement on system efficiency and independency. Great contribution from the system has been witnessed in snow disaster in south China in 2008, Wenchuan earthquake in 2008,  drought in north China in 2009 and drought in southwest China in 2010. The paper introduces the development of the system between 2005 and 2009 in systematization, independency, system application and system extension in detail, and then presentes a future perspective on the system′s development in the Twelfth Five Years (from 2011 to 2016).
