OpenStreetMap
This was my first attempt at editing Open Streetmap. I created a GPS trace and used it to plot Orford Avenue, Whitworth Drive, Vicarage Lane, Lime Close, Maple Close, Beech Close, Sycamore Close and Willow Close.
I'm not fully au fait with cartography yet, but I think this was a pretty good first attempt at the basics.
One thing I'd like to know, though, is this. Although Vicarage Lane is a continuous road, it is a 'no through road'. There are bollards at approximately the location indicated against this diary entry, meaning that although pedestrians and cyclists can pass through, cars cannot. (Most GPS systems wrongly treat Vicarage Lane as a through road.)
What is the best way of showing this on the map? If someone more experienced would like to do the necessary edits, I'd be most grateful.
Thanks.

How about
osm.wiki/Tag:barrier%3Dbollard
?

I agree with wieland: This should be mapped as a node with the barrier=bollard tag, if I understand your description correctly. Most existing routing software using OpenStreetMap data will not yet interpret this correctly, though, as it has been introduced only some months ago and requires significant software modifications.

If you're just starting out, take a look at here: osm.wiki/index.php/Map_features

Ah, come to think of it, a combination of
barrier=bollardandhighway=pedestrian(instead ofhighway=residential) would work better.msg_uk 于 2009年05月 9日 23:53 的评论
Thanks for the comments, everyone. I'll see if I can get a precise location for the bollards, then have a play.

Depending exactly on the layout, the usual way is to put a short length of e.g. pedestrianised road, cycleway, footway etc. representing the length that is not drivable. This will still allow foot/cycle traffic to proceed when routing - but will prevent cars from being routed down there. You can then furnish the gap with whatever e.g. bollards etc.
Remember that the pedestrianised road, cycleway etc. should be a short way - bollards are normally on nodes.

Even if you don't know the exact location, an approximate location is good to put it at. After all, someone can move it if they work out the exact location.

If you can cycle along the bit of road where the bollards are, you should have a short way in the middle of the residential, which is a cycleway. Most routing engines don't take into account the barrier=bollards yet.
