一
1.打开arccatalog 找到需要转换的线要素
E:\workspace\gy\map\xx\guiyang.gdb\一级道路

2.使用arcmap编辑线要素删除不必要的线要素.
3.使用arctoolbox工具中的 数据管理工具---制图综合---融合 把线要素合并成一条完整的线要素

注:融合工具中 融合_字段(可选)默认不需要选中字段,否则线要素不能融合成一条完整的线.
4.把融合后的线要素 E:\workspace\gy\map\xx\guiyang.gdb\一级道路_Dissolve加入到arcmap中编辑要素,选中要编辑的要素单击编辑工具中的---编辑折点,删除不需要的折点

7.等分线要素为点要素.
使用arctoolbox--数据管理工具---要素---要素折点转点

![](http://dl.iteye.com/upload/attachment/521575/93456c4b-8075-3aa5-8f33-b42fc10bfe43.jpg)
使用arctoolbox--数据管理工具---要素---在折点出分割线
8.给点要素添加ROADNAME和Mileage两个属性字段
ROADNAME为text类型Mileage为float类型
使用arctoolbox--数据管理工具---字段---添加字段

9.关联点要素图层和线要素图层
把一级道路_Dissolve_FeatureVertice,一级道路_Dissolve_SplitLine
加入到arcmap中,选中一级道路_Dissolve_FeatureVertice---属性(I)---连接和关联
![](http://dl.iteye.com/upload/attachment/521581/7f02285f-3374-30c1-b56d-216f92660730.jpg)
![](http://dl.iteye.com/upload/attachment/521583/7476da01-753b-3967-95a7-c8d971bf96f2.jpg)
关联完成后,单击把一级道路_Dissolve_FeatureVertice---打开属性表(T)
![](http://dl.iteye.com/upload/attachment/521585/47bafaf5-4764-301a-965b-2b0389a1d90f.jpg)
给属性字段填充道路数据和图形要素长度
选中表中ROADNAME单击右键在菜单中选中---字段计算器
