>Howdy,

>It looks like two of us had the same idea this weekend - Richmond Park is 
nice and big and needs adding. Since my bike is currently broken, I

it turns out that some bits are quite, quite different from way back in 
the >NPE era - specifically, there's a huge golf course in the NW corner, 
and another down near Ham in the SE, neither of which are part of the 
park. >More interestingly, perhaps, is that one big chunk of the park is 
now the (not so nice) Danebury Avenue housing estate, and even the 
Beverley >brook river seems to have been re-routed by a few hundred meters 
or so. I've appropriately tweaked the NPE-traced perimeter that was added.

historical stalwarts like Richmond Park get moved around over the >years.

IMX it's still very relevant in open countryside areas, which seem just 
about unchanged (round here at least) since NPE publication. I'm certainly 
confident enough of it to add a whole load of country lanes to OSM through 
it anyhow...

For obvious reasons it's less relevant in or near towns.
