[Openstreetmap] Downloading OSM data

[simon green]

Thanks for the help guys, I did manage to get this to work in the end. I've
done some simple perspective renderings of the London trackpoint data, but
this list won't let me attach images.

The track points don't always seem to be in time order -  i.e. if you draw
lines between them you often get a big mess. Why is this?

It's not map related, but here's a link to some of my visualization work:
