LDN title locations

Studying the opening titles closely on BBC LDN, it lead me to wonder where abouts the title locations were shot, as I don't recognise any of them, except the London Eye.

Does anyone recognise where they were shot, and does anyone here @ the forum live near any?

Well I think one of them is the M25 or one of the motorways, there's a tube station in one of the versions I've seen, and I think some of the shots are from the south bank.

Title sequence B, the first shown on Oct 1st at 6:30 has canary wharf station looking upwards through the glass roof as the opening shot. Love it! Was there yesterday night, looks even better when it's dark!
