摘要
农田地块是农田地理要素的典型要素。为此,分析了农田地块变更的数据源及其更新形式,并提出了农田地块更新模型,以便满足不同数据源的地块更新实现的需要,最后依据农田地块更新模型设计了面向精准农业应用的农田地块更新地理信息系统的体系结构、数据库结构及其功能结构。
Field parcel is one of the typical features in field geographical features, it analyzed the data-sources for obtaining field parcel changed information and the change modes of field parcel, then proposed the update model for field parcel to meet the demands realization of real-time update according to the data-sources. Finally, it designed a precision agriculture oriented system for field parcel information collection and update, mainly discussed the system architecture, database structure and function structure.
