Development of Precision Rice Cultivation Information System Based on ComGIS
Shunbao Liao · Geo-information Science · 2004
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 RD 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.
