Based The Microstation Scan Vector Software Development,

Along with the application of computer technology in the vocation of Cartography, All-digitalized technology & methods on map produce have been populized in army for surveying and mapping. It integrates theory and methods in cartology and computer graphics & image process organicly, and it had changed the method of map production.With the development of digital mapping technique and the broad uses of GIS,the requirement of geographical information was extended unprecedented. The development of RS technique and GPS technique and modern survey technique made the source of geographical information broad much more ,but papery maps which had been producted is fruits of survey and mapping in the past many years ,and yet its digitization is an important means to obtain geographical information. papery mapThis paper which starts from the actual needs of Digital Map Production System based on MicroStation software in map production, aimed at the problem of papery map digital, analyzed the wok flow of Map Scanning Vectorization System , investigated the theorys and methods of vectorization for Monochrome map image, accomplished the basic function that map scanning vectorization needs,and established a elementary Map Scanning Vectorization System based on MicroStation software.
