It's glorious in resolution alone, as the largest map of Tamriel I've found to date.
Also which locations are wrong? They all look correct to me: http://images.wikia.com/elderscrolls/images/e/e4/Map_tamriel.jpg
Yes I've played Skyrim. I guess I wasn't being clear, technically we're both right. The second map I linked to is the official map of Tamriel created by Bethesda. The map created by Belhene is basically a retexturing and rescaling of Bethesda's map. As you see it clearly lacks Solstheim as well (which is quite peculiar) and the positioning of Markarth Side different from that seen in TES V. Your observation was also correct, the map was clearly modified for the most recent game. I suppose that map is proper cannon now, and therefore the older map is outdated.
Oh and "Markarth Side" has been the name in lore up to TES V: http://elderscrolls.wikia.com/wiki/Markarth_Side
