摘要
在应用MAPGIS软件进行线条矢量化时存在着常规输入线的耗时及自动矢量化效果太差问题,交互式矢量化利用图形分层、人工干预线条走向、线条抽稀、线条光滑等手段,可有效克服矢量过程中出现的线条重叠和偏离现象,保证图件矢量化的效果。合理使用功能键进行退点、转换线向及图层屏蔽等技巧,可方便、快捷、美观的完成图形矢量化。
In MAPGIS software application,when arrow quantification line has a function to be called ＂the interactive arrow quantification＂,has some problems in the application,through to its good and bad points contrast,provides the method which may choose,causes the colleagues to use facilitates quickly completes the graph the arrow quantification process.
