摘要
根据遥感图像在WebGIS中的应用特点和目前存在的问题,利用富互联网技术Flex和图像处理语言PixelBender,提出了将遥感图像计算工作分配于客户端浏览器执行的系统架构。并按此架构开发了一个原型系统。运行结果表明,此种架构可以在WebGIS中很好地实现遥感图像运算与增强,用户体验优良。为扩展遥感图像在WebGIS中的应用提供了新的思路。
Processing remote sensing image was always a time-consuming task in WebGIS,because all the process was placed in server side.Presently,using FlashPlayer 10,Flex has the ability to leverage customized shader which can be written by PixelBender for image processing and enhancement.Based on this technology we designed a new WebGIS architecture,placing remote sensing image process in browser side.The result of a prototype system of this architecture is promising and shows that the architecture can achieve better performance than traditional methods.
