GIS Data of Street Center Lines

GIS Data of Street Center Lines

Post  maciasluis on Mon Mar 17, 2008 2:55 am

What I need is GIS data of street center lines where each street is represented as a line or polygon, with the GPS coordinates of the end points of each line, or node of the polygons included in the data.

I have downloaded street file samples, and looked at the .dbf tables using MapInfo. I see such fields as:

- Leftadd1
- Leftadd2
- Rightadd1
- Rightadd2
- StreetNames

but cannot find GPS coordinates. Mind you, there are other files with extensions: .sbn, .shp, .shx, .sbx which I know nothing about.

Is there a companion file I should be looking at?

TIA.

Klaus,

Not sure what GIS you are using (but assume it is ArcInfo - seeing you list esri files in your post)

Check out the following URL - it is for MapInfo users, but I assume you could do something similar with ArcInfo - if that is what you use.

The posts in the link detail a number of methods of getting the beginning and end co-ords of your line segments.

Hope it helps.

Cheers,

Brian
