Abstract：This paper describes the scanning techniques for GISdata inputing and presents, a new scanning vectorization scheme based on greyscale image processing. Asoftware system named MAPINis developed according to this scheme.The key techniques of the system, such as adaptive line following,automatic image editing, whole image vectorization, sub-pixel location of control points, vector data connection, and so on, are discussed emphatically in the paper. Finally some experimental results are given to illustrate the feasibility of the scheme and the practicality of the system.
