Abstract:

Predicting the grain production duly,objectively and exactly has great 〖JP2〗importance to the constitution〖JP〗 of grain policy,the control of food price and economic trade,the security of foodstuff,and the regulation of planting structure.This paper introduces the Hubei Crop Watch System with Remote Sensing,based on the remote sensing data,statistical data,meteorological data,field data and other data.The system utilized DBMS as the database platform,adopted the systematized framework of Client/Server(C/S),and it was developed by Interactive Data Language (IDL) with the character of orienting matrix.Hubei Crop Watch System consists of several components,including crop condition monitoring,〖JP2〗crop acreage estimation,yield prediction,and grain production estimation〖JP〗.The system is fast with stable operations and high efficiency,and it can provide accurate and reliable results.Thus the system could provide reliable information services for agricultural decisionmaking supporting and grain production of Hubei Province。
