| Abstract: | 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. |
