摘　　要：针对海量遥感影像地图在现有GIS软件中不能显示或显示速度缓慢的问题,本文研究了遥感图像的分层分块方法及在MapX中动态加载的方法,提出了构建基于MapX的海量遥感影像地图浏览平台的原理、方法及操作步骤。遥感影像地图分层分块采用了四叉树分割方法。分块图像在MapX中动态加载方法通过实例验证,效果良好。Aiming at the problem that current GIS software can not display the massive remote sensing image map,or can display in a low speed,the study on the delaminating and blocking method of the remote sensing image,as well as its dynamic loading method in MapX are expounded in the paper.On this base,the construction principles,methods and steps of massive remote sensing image browsing platform are established.The method of delaminating and blocking of remote sensing image map is quad tree segmentation.Dynamic loading method of block images loading in MapX shows good effect by the case studies.
