In 1st July 2007, China Government formally started a great project named "The Second Survey for the Land and Resources". China plans to investigate the current landuse status, and realize the land and resource informatization during two and a half years. Vectorization of Scanning Landuse Map plays an important role in land informatization and digital land project. Traditionally, it's very laborious and time-consuming to digitize from scanning landuse map by hand. Aiming at these problems, this paper designed a technology flow process for automatic vectorization of scanning landuse map based on mathematical morphology. Many key techniques, such as noise reducing, image thinning; separation of graphic and text were studied in this paper.
