Use Image Based on JPEG2000 in Web GIS
基于JPEG2000标准的遥感影像在Web GIS上的应用

The Internet GIS provides an open and normative environment for people to share the geographic information, the common resource of Human Kind. In particular, from 1998 the project of Digital Earth has been progressed forward. It is no doubt that the image of RS will play an important role in the progress of building the Digital Earth. But now there is a big gap between the bandwidth and the size of image, which has affected the application of RS image greatly. Therefore, in 1997 the International Standard Organization associated with Joint Photographic Experts Group began to set up a new coding system of still image-JPEG2000, which will solve this problem perfectly. This paper presents the archtecture of Web Gis application based on JPEG2000.
