Since common management information systems are not suitable to deal with these spatial distributed data , it is needed to develop a field level geographic information system ( fis ) , in order to meet the needs of field data processing and field information management 由于這些數(shù)據(jù)一般都具有空間分布上的特性,要分析與處理這些數(shù)據(jù),普通的關(guān)系型數(shù)據(jù)庫已不能滿足需要,因此需要開發(fā)一種田間信息系統(tǒng),或者稱之為農(nóng)田地理信息系統(tǒng),來對田間數(shù)據(jù)進行分析與處理,并對農(nóng)田信息進行管理。
