基于移动GIS的农业信息采集系统

随着智能终端、嵌入式技术和无线通信技术等的不断进步和发展，移动GIS突破了硬件和软件的瓶颈，实现了多领域的扩展和应用。移动GIS因具有实时更新、协作同步、数据共享等特质，成为数据采集领域应用的主流技术。以移动GIS组成及系统结构为研究基点，在深入分析农业信息采集系统的功能需求基础上，采用PDA为基础硬件平台、SQL Server2005作为数据库支撑，以Visual C++ 4.0进行编程开发，介绍了系统架构、功能模块及开发环境，该系统能够有效满足农业信息的实时定位、采集及传输需求。 

Agricultural Information Collection System Based on Mobile GIS

With the continuous progress and development of intelligent terminals，embedded technologies and wireless communication technologies，mobile GIS has broken through bottleneck of hardware and software.Mobile GIS has realized expansion and application in many fields.Due to characteristics of real-time updating，collaboration synchronization，and data sharing，mobile GIS has become mainstream technology for data acquisition applications.Based on this，taking mobile GIS composition and system structure as basic research points，based on deep analysis of functional requirements of agricultural information collection system，the PDA was used as underlying hardware platform，SQL Server2005 as the database support，and Visual C++ 4.0 was used for programming and development.The system architecture，functional modules and development environment were given.The system can effectively meet real-time positioning，acquisition and transmission requirements of agricultural information.
