基于Flex Viewer框架的北冰洋海冰卫星遥感信息系统的设计与实现

北冰洋是世界上最小、最浅和最冷的大洋,位于地球最北端,终年覆盖着海冰,是地球的最大冷源之一。北冰洋的海冰变化在不同的时间尺度上影响着全球的气候变化。卫星遥感技术是海冰监测的有效手段之一。目前为止,国内外相关海冰研究机构已获取了三十多年的海冰数据,这些数据是今后更加深入地开展北冰洋海冰研究的重要依据。针对海量的海冰卫星遥感数据,在Flex Viewer开源框架下,利用互联网应用(rich internet applications,RIA)技术和Web GIS技术,开发了北冰洋海冰卫星遥感信息系统。系统具有GIS功能强大、界面友好、平台无关以及开发效率高、开发成本低等优点,为北冰洋海冰遥感数据采集、查询、空间分析和实时数据服务的网络应用提供了一种很好的解决方案。

Design and implementation of Arctic Ocean sea ice satellite remote sensing information system based on Flex Viewer

The Arctic Ocean, located in the Earth's northernmost, is the smallest, most shallow and the coldest ocean all over the world, and it is one of earth's largest cold sources because of the Polar Ice Packs. Changes in the Arctic sea ice affect global climate change at different time scales. Satellite remote sensing is one of the most effective means of sea ice monitoring, so far, native and foreign sea ice research institutions have access to a large number of sea ice data for more than thirty years, which is an important basis for in-depth research. We developed the Arctic Sea ice satellite remote sensing information system based on flex viewer with the help of RIA and Web GIS technology. The system has powerful GIS function, friendly interface, platform independence, development efficiency, and low cost advantages. It is a good solution to web applications that achieves remote-sensing data collection, query, spatial analysis and near real-time services of the Arctic sea ice.
