This paper firstly analyzes problems existing in current rectification software

then presents a new rectification approach based on image and graphics overlaying and matching without the support of digital elevation model

and introduces fast overlaying technique of image and graphics based on indexed-color mode.To make rectification

this paper analyzes the feature of partial deformation

and presents a rectification formula for partial deformation based on experience.Finally

software of image rectification is developed combined general rectification and partial deformation rectification.In the experiment

a test image is rectified using the software with 13 selected control points

rectified image match the map very well by overlaying

and errors left are all within 2 pixels.The results show that rectification approach this paper presents is feasible and can be used to rectify image deformation induced by any factors.
