enigmatic puzzle - What number is hidden in this map?


This question is part of a puzzle crime story I have started recently (you can see previous puzzles from the series HERE, HERE and HERE). I would like to test the difficulty (not sure if too easy or too hard), and possibly get some feedback/ideas for improvement. The text looks a bit out of context, but the backstory is not necessary to solve the puzzle. The goal is to find a 4-digit passcode encoded in it.




Sanders arrived home and looked sick. He closed the door behind him, took off his coat, and slowly went to the living room. He opened a cupboard, took out a pack of cigarettes and lit one. He quit smoking two years ago, however today he couldn’t stop himself. Sanders turned around and went to his “memory” wall – the place where he used to hang all his favorite pictures. He stopped in front of one of them and looked at it…

“Oh Teddy…” Sanders muttered and shook his head. He took the picture in his hands, sat in an armchair, and stared at it. Suddenly, he felt something attached to the back of the photo. He turned it around and saw a map.

Initially Sanders was confused – he couldn’t see written coordinates on the map or a target place on it. After few minutes of contemplating however, he stood up, put his coat back on and left. He knew exactly where to go.




P.S. I know, probably I won't become a world-renowned writer.



Answer



Not sure if this is right, but here's my guess.


There are some hidden




Letters in the map that seem to spell "trees". This could hint that the trees are important.

Notice that there are



10 different tree symbols on the bottom and left side of the map. This might mean they should be translated into digits.



Since the thing in the



lower left corner seems like an "origin", I assumed that we're dealing with sort of an x-/y-axis situation, and the numbers increase to the right and up. Based on where the first digit changes, we can fill in some of the numbers (again, assumption: step size of 1).

enter image description here



Then we have only



three remaining unused digits (4, 5, and 6) and so can fill in the rest of the map.
enter image description here



Then if we



overlay the photograph, we notice that the cross in Teddy's hands marks a particular box.

enter image description here



And taking the



x/y coordinates of that square, our 4-digit code is 5259.
