WANG Tao, DENG Xue-qing, DAI Chen-Guang, ZHANG Yong-sheng(Information Engineering University , Surveying and Mapping Institute, Zhengzhou450052,China)  
According to the characteristics of intelligent mobile terminals represented by PDA, a new dada model based on the tile-pyramid is presented and linear quadtree is used for remote sensing image management and display. The related dada structure of the model is explained in details, and the real-time display of the image dada is achieved by the view-dependent real-time simplifying algorithm. The experimental results show that the model and the algorithm can enable real-time display for massive remote sensing images under PDA with limited resources.
