Don’t expect the Ordnance Survey or any of the other professional mappers to help you in finding Terminal 5 at Heathrow.
Yep, you have to rely on Open Street Map. See how the other’s handle it on the opengeodata blog.

The OSM map data has received some attention today (largely as a result of my blog entry) and there’s now even more detail visible.
The most current OSM map of terminal 5 can be viewed here:

Thanks Etienne, I thought that would be the case so I made the map in my post clickable to the latest OSM one.

Jon it seems OK here lat=51.471&lon=-0.4583&zoom=14&,comment the correct link and I will add it
