摘要
提出了基于全球剖分格网的大数据量遥感影像快速显示方法,并基于VC平台实现。测试表明,它具有LOD技术优点,兼有影像金字塔的长处,并且利用剖分面片无缝铺盖球面的性质和地址码的关联性,可解决图像的重叠问题,能实现遥感影像的快速搜索与显示,具有局部图像快速更新、图像无缝连接等优点。
With the development on the technique of the remote sensing,RS images are becoming the most important data source of GIS. As the RS image＇s data quantity is increasing with the improvement of sensor＇s resolution,it brings a big trouble on viewing images quickly. This paper puts forward a method based on Global Subdivision Grid which can quickly view RS image, using the model address coding relation and its partition units covering the global seamlessly. The problem of large data quantity viewing in PC can be solved using the method,and the method has the advantage of LOD and pyramid-image.
