摘　　要：针对传统影像组织方法——瓦片金字塔模型实现海量遥感影像调度存在的问题,提出一种瓦片实时切割与高效调度的新方法。在.net平台上使用C#语言开发了基于瓦片实时切割与调度和瓦片金字塔模型两种方法的瓦片服务发布系统,并用实验进行了对比分析。实验结果表明,新方法无需创建瓦片金字塔模型,节省了大量的时间和空间;同时瓦片调度速度有所提高,从而实现了海量遥感影像实时切割与高效调度。Based on the problem of massive remote sensing image scheduling with the traditional method of tile pyramid model, a new method which is called tile cutting implement and efficient scheduling was proposed. The tile service system based on the tile cutting implement and efficient scheduling method and tile pyramid model was developed by the C# language in . NET platform. A comparative analysts has beert down through the experiment. The results showed that the new method does not need to create a pyramid model and a lot of time and space has been saved, and at the same time the speed of tile scheduling is increased. Thus the massive remote sensing image in real-time cutting and efficient scheduling can be realized.
