These look more like watering holes (with animals) than houses...

I don't think these are houses.
There are no roads or bare earth around them where people have been walking

National parks here need area of forest shown (natural=wood)

Turn lane mapped wrong.
This is not divided from the main northbound lanes, hence should not exist as a separate road.

EN: The topgraphy layer (open cycle map) has many false deep pits in this area. The Digital Elevation Model needs to be updated to fix these.

Routing at this roundabout is messed up.

Despite adding turn restrictions, I am finding that the following routes give incorrect roundabout exit numbers:

1) South-east from Staines By-Pass to A308
2) North from London road to Sanwell Moor Road

Is this still incorrectly mapped or is there a bug in the routing code?

I don't think these are buildings - there's no tracks to them, nor any bare earth around them
