Quickly Create the Water Function Districts Evaluation Map Based on MapInfo

水功能区评价图是水行政主管部门了解水功能区质量的常用图件,图形内容直观明了,但采用传统CAD方法制图效率很低,无法重复利用。基于MapInfo软件强大的接口功能、方便的图层管理功能和灵活的专题图形功能,文章在数字地图的基础上提出了快速制作水功能区质量评价图的方法,且运用MapInfo的数据更新功能使得重复制图变得更为简单方便。

The evaluation map of the functional districts of water is the staple map used for the water administrative responsible institution,which has the direct viewing figure but troublesomely charting.Traditional Cad drawing methods are inefficient and cannot be reused.A new method is introduced in this paper based on the digital map,which can make pictures speedy with the powerful interface function、the convenient management function and the flexible graph function of MapInfo.Moreover,repeated charting became simple and convenient by using the data updating function of MapInfo.
