【摘要】 在分析现有几种主要的WebGIS遥感影像发布解决方案及各自特点的基础上,针对遥感影像数据发布模式的不足之处,为解决影像在线浏览速度,提出了一种基于AJAX模式的WebGIS遥感影像数据发布解决方案,并在ArcIMS平台上开发了WebGIS遥感影像数据的发布系统。在当前Web2.0互联网应用迅速发展的形势下,这一方案有效解决了WebGIS遥感影像数据发布速度问题。更多还原

【Abstract】 Based on the analysis of several current WebGIS solutions for the publication of remote sensing image on the Internet,the authors conclude that these solutions have obvious limitations in publication of remote sensing image.In order to get higher performance with additional functionalities,they integrate a new model-AJAX(Asynchronous JavaScript and XML)-into image publication system and implement this online publication system for remote sensing image.As the Web2.0 platform continues to mature,this approach has made some attempts to improve the traditional method in WebGIS for image publication.更多还原
