| 摘 要： | 光栅自动矢量化的发展是GIS发展的产物,目前矢量化的方式主要有交互式矢量化和自动矢量化两种。两者相比,自动矢量化不需要人工的干预,能够自动完成矢量化过程,节约了大量的人力物力和财力,同时大大提高了光栅图像矢量化的速度.

| Abstract: | the development of vector of raster is the produce of GIS.At present,there two vector ways-alternating vector between person and GIS and auto-vector.Comparing with two means,auto-vector dose not need person's interference and can complete vector process by itself.In addition,the method can save a lot of labor resource,substance resource and investments.Finally,the way will improve the speed of picture management. |
