Abstract

This study focused on the theorial model and application foundation to solve some problems of global expanding spatial data. A global subdivision model of the Extended Model Based on Mapping Division(EMD) is introduced and used to establish a template-based rapid processing mechanism for Remote Sensing(RS) images. According to the parallel processing flow of RS images and their basic spatial relations, four kinds of computing modes are established to improve the processing speed of RS images. And a group of RS images are used in experiment to verify these operations in RS application. The results shows that this method is benefit for browsing, moving or transforming the RS images. This work provides the possibility and practicable foundation for rapidly applying RS images, and promotes practical application of EMD subdivision model.
