摘　　要：将静态的纸张和影像地图及传统的各类地理信息转化为数字时代的电子信息,其中的关键环节是怎样将栅格数据矢量化。通过在国产软件SuperMap环境下进行栅格数据矢量化过程,详细描述了栅格数据、矢量数据、坐标系、投影坐标系、地图配准和镶嵌等专业基础知识在实际中的应用。Vectorization of raster data is on of the key steps during the transformation from static paper map, image map and various kinds of traditional geographic information to electronic information of digital echo. By the implementation of vectorization of raster data based on SuperMap which is a national software, this paper discussed the practical application of professional basic knowledge, including raster data, vector data, coordinate system, projection coordinate system, map registration and mosaic.
