Literary Geography because:
Ian Fleming stated that SMERSH HQ was in 13, Stretenka Ulitsa, Moscow, so a reader sent him a photograph of the building to show that it wasn't;
much of North America is "Montival";
Nicholas van Rijn has a penthouse in Chicago Integrate (see here), a mansion on Kilimanjaro (see here) and an office in Djakarta (see here);
Terran Admiralty Center is in the Rockies (see here) but we are not told where the capital, Archopolis (see here), is.
I suppose that future and alternative geographies differ from allegedly real geographies. Fleming claimed in an Author's Note that his information was accurate. But, in terms of literary geography, SMERSH HQ is exactly where Ian Fleming says it is.
