摘要
针对扫描矢量化过程不同阶段存在的扫描图象可视化、线条有效提取、变形数据校正等问题，提出或发展了解决相应问题的方案．相应方案在ＭＡＰＧＩＳ基础平台的ＭＡＰＲＶＳ智能矢量化系统中得到精巧实现。
This paper analyzes the key factor of the problems existing in the process of raster_to_vector, such as scanning image visualization, extracted line vectorization, distorted data correction etc.. It gives a new method to solve these problems. The new method is implemented in MAPRVS, which is a raster_to_vector subsystem of MAPGIS.
