【Abstract】 Development of geographic information system based on COMGIS has advantages of short development time, low cost, no need of additional GIS development language, and good incorporation with models related to rice production. COMGIS has become the main mode of geographic information system development. This paper elaborated the basic concept and technique foundation of COMGIS. By insertion of MapObjects component into the VB development environment using COMGIS techniques, management information system was established to supervise synthetically information related to rice production, such as climate, soil, water resource, agricultural economy, and basic geography, etc. This system can realize the general GIS function and the professional analysis function. Finally, the application of GIS technique in agricultural management was discussed.更多还原
