基于GML的精准农业数据交换模型

Precision Agriculture Data Exchange Model Based on GML

精准农业数据的多语义、获取手段多源、存储格式多样和空间基准不一致等问题已经成为制约精准农业技术集成与深入推广应用的主要障碍。为此,针对精准农业相关数据主要为空间数据的特点,设计了精准农业空间和非空间一体化数据模型,基于GML表达了精准农业数据模型的要素,给出了要素对应Schema。由此建立了通用的精准数据交换格式,方便了GIS应用软件之间数据交换、共享与互操作。

Problems which are multi -semantic, multiple medium, many memory format and spatial datum disunity exist in precision agriculture data. Agriculture integration and application technology have been inhibited. The spatial, traditional concordant data model of precision agriculture is designed, which aim for most spatial data in precision agriculture. Feature classes expressed by XML Schema, are presented by GML implementation specification. Universal data exchange format have built up in order of data share and interoperation.
