() Abstract
Since CBERS-1 was launched in October 1999,it had been running normally more than 4 years to 2004 and received tens of thousands of images.This paper introduces some key techniques,such as removing streaming noise of CBERS-1 images,image enhancement,geometric correction,image mosaic,and color adjustment.What's more,this thesis introduces the work flow and cartography criterions of using CBERS-1 images make China digital mosaic map.
