As a basal part of the whole project, this study is demanded to provide necessary data for other systems. One of the tasks is to extract vector data from raster images.
作为项目的基础性部分，本课题需要为其它相关的课题提供所需的数据，其中很重要的一项任务就是从栅格影像中获取矢量数据。
The SOCET GXP v3.2 software release also adds automated tools for viewing and editing live video feeds, and efficient tools for converting terrain analysis results from raster to vector file format.
该SOCET GXP V3.2软件还增加了用于查看和编辑实况视频的自动化工具和用于转换地形分析结果(从栅格转为矢量文件格式)的高效工具。
It is also very easy to convert from vector to raster formats, but the same ease doesn't hold true vice-versa.
将矢量图转换为光栅图也很简单，可反过来则不行。
