[OSM-talk] transparent road layer

Thanks everyone for responding. Here's what I found:

geoiq has a nice road layer that is very simple, no icons, just white roads
with legible labels. Depending on your application, the simplicity of the
acetate road layer can be appealing:

With the help of Ant and Deborah from MapQuest I was able to get the URL of
mapquest's transparent road layer that's part of their hybrid layer:
http://vtiles01.mqcdn.com/tiles/1.0.0/vy/hyb/z/x/y.(<http://vtiles01.mqcdn.com/tiles/1.0.0/vy/hyb/13/2479/3029.gif>
gif|png)

Note: looking at just a couple of these tiles, I'd recommend using the gif
format since the tiles are about half the file size and the PNG doesn't
appear to have any alpha anti-aliasing

For reference and comparison, here's google's version of the same tile:
(http://mt0.google.com/vt/lyrs=h@156&hl=en&src=api&x=2479&y=3029&z=13&s=Gal --
but don't use this URL in an app, you'd be in breach of their license
agreement)

and MapQuest's satellite tile:
