Don’t worry, I didn’t consider your answer “rude”… I just wanted to clear things up, before we run into some missunderstandings 
.
I use the definitions from the document linked by Zhilkin for my descriptions in combination with your screenshots (a bit out of order).
I’ll go through everything, even the “easy” ones, just so I can refer back to stuff here. So, let’s get started…
These represent the overmap coordinates. The LEVEL 0 is the current z-axis of your marker, the 0'(173) is the current overmap coordinate of the x-axis, the (0’)173 is the overmap terrain currently marked by your cursor in the x-axis of that overmap, the -1'(173) is the current overmap coordinate of the y-axis while the (-1’)173 is the current overmap terrain (or overmap tiles, as I’ll call them from now on) of the y-axis.
So, from the “middle” of the game, the overmap 0'0, 0'0, you moved or started one overmap higher, and on that overmap you’re 173 overmap tiles to the right and just as many tiles down from it’s left- and uppermost point. And you’re also on the surface, since the Level is 0.
The <60,67> are the coordinates of your cursor, relative to the Local coordinates. It starts with <0,0> at the left upper edge of the reality bubble (the part of the world that is currently loaded and calculated by the game).
So your marker is 60 map squares (I’ll call them just tiles) to the right on the x-axis and 67 down on the y-axis from the start of the reality bubble. The z-axis is not shown here.
The 60:67 is again your position in the reality bubble (as described above), which starting point is located in 341:-19. The 341:-19 are the coordinates of the submap your reality bubble is currently in. From what I can tell, these are Absolute coordinates.
So, based on the overmap coordinates of 0'0, 0'0, you’re 341 submaps to the right on the x-axis and -19 “down” (since it’s negative, it’s actually “up”) on the y-axis.
So, let’s check these values…:
- 1 submap is half an overmap tile.
- So 341 submaps mean 170.5 overmap tiles to the right from 0’0 on the x-axis and -9.5 up from 0’0 on the y-axis.
- Now we end up with 0’170(.5) and 0’-9(.5) (or -1’170(.5)) in overmap coordinates.
- Pretty close to the 0’173, -1’173 you’ve got on the overmap, but not quite… but, as written, this is the start of the reality bubble.
- Your position is shifted 60 tiles to the right and shifted 67 down, so (1 overmap tile is 24 map squares) +2.5 overmap tiles to the right and +2.5 overmap tiles (and 7 map squares) down; we’re spot on where you’re standing.
Your local position: 60, 67, 0 is once again the coordinates relative to the start point of the reality bubble, this time with the z-axis also represented.
Your noble steed “Horseratio” is (again relative to the start point of the reality bubble) on the coordinates 68, 87, 0, or 8 tiles to the east of you and 20 tiles south, on the same z-axis as you are.
Your overmap position: 173, -7, 0 are straightforward your overmap tiles, this time in absolute coordinates (relative to the 0’0, 0’0 overmap tile).
Ah, yes. Thank you for your explanation. I thought you were talking about the number that you can find next to terrain, for example the 4 in [...],["t_grass",4],"t_dirt","t_grass",[...]. Good thing I asked 
.
Short answer; I think these are indeed coordinates (relative to the submap), but I have to test a bit. Luckily I’ve found my “older post” mentioned in that other topic, so it should be easier to figure it out again.
I do have to do some other work though (and probably also sleep a bit), so I’m going to add the explanation for the coordinates of the save system tomorrow… I hope the wait isn’t too dramatic.
