Need Help - Louisiana GIS Data
« on: November 09, 2018, 10:15:02 PM »

I'm trying to write an article about US 80 in Louisiana on Wikipedia (which is currently in my user sandbox) and I can't make any sense out of the GIS source used by most articles to measure the highway's distance or mile markers. Can somebody please help with that? I want to put down the total mileage and mile markers for major intersections for US 80.

http://wwwsp.dotd.la.gov/Inside_LaDOTD/Divisions/Mgmt_Finance/GIS/Pages/GIS_Data.aspx

This is the source most Wikipedia pages use for the mileposts and total length reference. Im having trouble figuring it out. Honestly, I wish Louisiana had a state highway log.

A couple of years ago when I was making KML files and maps for Louisiana highway articles there (most of which are now redirects and the KML files don't work anymore anyway :( ), IIRC the GIS file was really only good for determining if a route existed and getting a total length of a route. If I was updating the route junction list and needed the mileposts, I just got them from Google Maps. I started by getting directions from the starting terminus and then just dragging the end point to each route/interchange.

Thanks for the tidbit. This information helps a lot. I currently put the Louisiana article on hold to work on an Alabama one.
