摘要
利用遥感技术及时、准确地掌握主要粮食作物种植面积,对相关部门制定农业生产和农村政策具有重要的意义。针对目前商业软件(ERDAS、ENVI等)存在业务性不强、数据组织管理无序、难以操作等问题,设计并实现了一套适合粮食作物种植面积遥感测量业务软件系统。该系统以遥感技术和空间抽样技术为支撑,采用3层软件架构模式,实现了遥感图像处理、粮食作物面积测量、海量遥感数据管理等功能,具有业务流程明确、数据管理有效、升级快速便捷的特点,能够很好地满足业务化运行需要。通过2009年北京市冬小麦面积遥感测量业务运行,证明该系统能够简单、快速准确地测量出冬小麦的种植面积,达到满足业务化测量精度和时效的要求。
Timely and accurate major crop plant area data has a great significance to the relevant departments and the development of agricultural production and rural policy. In this view,designing and implementation of crop plant area monitoring system based on .NET is necessary. The system uses three-tier C/S framework model,for scientific and advanced remote sensing techniques and statistical sampling techniques as the support,it can realize many functions such as the remote sensing image pre-processing,crop plant area monitoring,mass remote sensing data management,production web publishing and so on. The rigorous system testing and operation has been conducted,which proved that the system was stable and efficiency. It can be concluded that such system is widely useful for the relevant departments about agricultural statistics with timely data for decision-making support information.
