What is the maximum number of Locations Discovered that one can achieve in Skyrim?

Under Stats | General, there is a counter for Locations Discovered at the top. What is the maximum number one can achieve in this? I have tried googling the answer but I am not able to find satisfactory answer.

There are some self reports of people achieving 348, 329 or 323 in various places in internet and some obviously wrong answers like 719, but strangely enough I am not able to find definite answer for this. Is there a way to find out a definitive answer?

Solution 1:

Well according to the Skyrim wiki there are 719 locations. Link is here

EDIT

Sorry the above answer has overlapping locations:

Another link in the wiki states there are 616. This includes locations in cities as well.

Second Edit

Sorry I misread your question. This link is to gamshee and show all the locations just on the skyrim world map (which should all be discoverable). There is a total of 343 locations on this map.

Solution 2:

I have found 363 on xbox360. That includes all dlc including the 3 land plots you get in hearth fire.

Now I can't discover the 4 imperial camps due to the choices I made in game, but this should be actually total. I compared to an online map when I had 361 and found 2 plus 4 imperial camps that I did not have on my ingame map.

By the way, I have 367.33 hours on game so I was very thorough.
