道路形状文件名称
我有一个带有道路网络的形状文件，看起来道路都被列为 1 条大折线。这是典型的吗？是否有可能获得一个道路网络，其中道路单独列出并具有与其关联的名称？
谢谢， 杰夫
I have a shapefile with a road network and it seems like the roads are all listed as 1 big polyline. Is this typical is it possible to get a road network where the roads are listed individually and have names associated with them?
thanks,
Jeff

如果有人给我发送了一个道路形状文件，其中所有道路都是一条折线，我会认为这个人在跟我开玩笑。
通常，有用的道路形状文件至少会被分成每条定义的道路的单线，或者更好的是网络交叉路口到交叉路口线段形状。
将一条多段线分割成更有用的多段形状文件并不是一项简单的任务。
进行快速的谷歌搜索会返回一些形状文件编辑器的免费解决方案，尽管我不能保证其中任何一个。我使用公司自己的 C# 代码库，使用 Tatuk 进行工作与形状文件。
If someone sent me a shapefile of roads where all the roads were a single polyline, I would assume the person was playing a practical joke on me.
Typically, a useful shapefile of roads would at least be broken into a single line for each defined road, or even better, a network intersection-to-intersection segment shapes.
It's not a trivial task to split up a single polyline into a more useful multi-segmented shapefile.
Doing a quick Google search returns a couple of free solutions for shapefile editors although I can't vouch for any of them. I use my company's own codebase written in C# using Tatuk for working with shapefiles.
