All, I’m looking for general techniques in how to best manage rendering of over/under roadway and rail road bridges, etc.
My first thought was to use some sort of special overlay layer to handle this. But maybe a database appraoch might be better. I also start to fall into the problem of having a lot of transporation related layers, Streets and Railroads obviously, but the not the so obvious are Alleys, Sidewalks, Park Trails/Paths, Bike Routes, tunnels, etc. How to make these all stack nicely. I generally maintain these things all in thier own grouping right now as separate datasets. They originate from separate authors and are maintained that way too. Which is why I was thinking that a DB approach might be the best to make the Z-indexing work. Thoughts? Thanks bobb "Reality is merely an illusion, albeit a very persistent one." - Albert Einstein
