Nice screen shot!

Hope to make this easier soon (might add a ticket on trac for "save this map" links from view-map), but if you want specific areas you can quickly hack around with the URL of the image in view-map so long as you get the proportion of width and height right. 1280x914 seems a nice compromise.

Here's London...

North/south divide?  Not much!

It may not be as one sided as you think though, although I admit the
grid-iron does figure more strongly in the older town centres. Look at all
those little cul-de-sacs in the newer residential areas. They are
effectively linear rather than grid and because of all the modern curved
roads there are loads of nodes. From all the cycling I have done up and down
this area I can say that there have been a lot more cul-de-sacs than grids.

You're right about the character of most streets, and of course the more detail you add then the less the number of nodes and lines will diverge. That's why we're accounting for a 2% divergence rather than the pure-grid divergence which would tend to 100%...

These little quiet cul-de-sacs should also carry an OSM warning about
getting funny looks when slowly riding a bike down the middle of the road in
a florescent cycling jacket. "You can't get out of here mate/love/dear"
seems to be the general response :)


This is just asking for a video to be made... Day in the life of a mapping activist :)
