| Abstract: | With the development on the technique of the remote sensing,RS images are becoming the most important data source of GIS.As the RS image's data quantity is increasing with the improvement of sensor's resolution,it brings a big trouble on viewing images quickly.This paper puts forward a method based on Global Subdivision Grid which can quickly view RS image,using the model address coding relation and its partition units covering the global seamlessly.The problem of large data quantity viewing in PC can be so... |
