<p class="MsoNormal">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. <o:p></o:p></p>

<p class="MsoNormal">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.<o:p></o:p></p>
