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

A:
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.

Ah yes, thanks. I misunderstood the output I was getting from my shapefile library and thought it was one polyline, but it was actually multiple lines. I still can't seem to get the names but that could be because the .dbf file doesn't have good information. I'll try out these editors, thanks.
