How to read map coordinates?

I have a map of some property that is (apparently) marked in coordinates. I'd like to use my iPhone to locate the property corners but can't make heads or tails out of the markings on this map.

For instance, one side of the land is marked: S - 46 - 22 - 25 - W
That side meets up to another side marked: N - 44 - 44 - 35 - W

Can someone help me to make sense of all this so I can plug some information into this iPhone app called GoTo Coordinates.

Thanks!

Added (1). Thank you for these replies. It appears what I have is called Property Coordinates and not real map coordinates. For these to work I must have a point from which to work from… Perhaps a stone pile as it says on my (not very clear copy of the) property map. Then you walk so many feet in a certain compass direction to the next "stone pile" and so forth.

Not for the faint of heart. Not sure if these can be converted somehow. For now I will see if I can find the stone piles.

Normally in mapping your coordinates will run northing and easting. I take it you're only trying to locate one side of your property line? It also depends on how old the survey was last done. If older than 10th yrs or so you'll have different gps coordinates we use today, not by much though. From the way this sounds, one corner is SW and the other NW. Is there any description as to what kind of corner the maps says? Some old places over 100 yrs could be marked as a tree. So you have to know what you're looking for. You might could go to the county register of deeds and get a copy. As far as coordinates, itll run degrees, minutes, and seconds. As a land surveyor, you never know what you're getting into until you get out and pull some distances or looking at the map. Honestly, what doesn't sound right to me is 46 degrees S and 44 degrees N. That is a very vast amount of land to cover.

I do not know.

The difficulty is that unless we know which organisation did the mapping, we can't tell what form of coordinates they were using. It doesn't look as if those are recording latitude and longitude, which is the only internationally used system which will let you find anywhere in the world. Most detailed maps, produced by national or local governments, are based on an arbitrary grid which has a fixed starting point chosen by the map makers. Your figures do not fit the OS sytem used in the UK - so I can't tell you where they are unless you tell me who produced the map they are taken from.
