基于组件GIS的精准水稻种植信息系统的开发

组件式软件开发已经成为当今软件技术的潮流之一,基于COM的组件式GIS开发技术近些年来广泛应用于GIS工程中。精准农业(PA)是GIS、GPS、RS等信息技术综合在农业生产中的典型应用,这一应用需要集成的信息处理系统软件支持。本文就上海精准农业试点中的配套软件“精准水稻种植信息处理系统”(PRC/INFOV1.0)的研制过程对组件GIS的开发与集成技术进行探讨。

Development of Precision Rice Cultivation Information System Based on ComGIS

Component software development has become one of the main technique trends nowadays. Development technique based on COM-GIS has been widely used in GIS projects. Precision agriculture is the classic application for integrated GIS,GPS and RS,and this application needs support of farm GIS software. The paper studies the R&;D of Precision Rice Cultivation Information System (PRC/INFO),which is used in China Precision Agriculture Experimental Unit in Shanghai.The paper analyses the key technologies and information procedure of precision rice cultivation initially. PRC/INFO can be decomposed by 5 parts in its general design based on its business logic. They are Attribute DB Management,Cropland GIS Management,Decision-making System of Rice Cultivation,Economic Evaluation System and System Integration. All the modules are organized in an integration system. Cropland GIS system provides the I/O interface and APIs for the whole platform. PRC/INFO is designed to be supported by ComGIS technology on the foundation of cropland GIS module. The platform is developed by Object-Oriented programming language. Its integrated development environment includes MS Visual Basic 6.0 components,SuperMapIII GIS components and lots of rice cultivation models. ComGIS development technology’s advantages are proved suitable to PRC/INFO in the development experience.
