X Marks the Spot

Week 2

It's 1753 and you are sailing along the north west coast of some unknown island, at which point you notice what looks to be an abandoned ship floating aimlessly in the sea

You decide to investigate and after boarding, quickly spot a dead body containing gigantic bite marks, slashes and broken bones

The ship is fully stocked with luxuries, alcohol and other items typical of a pirate

Along with the body, you notice a shovel still fresh with wet sand and mud, a map of the island and its surroundings as well as some kind of recording device that seems to be chronologically plotting the person's movement

Below is the data stored on the recording device - you notice how the last 2 values are in a different format than the rest of the data - can you figure out the co-ordinates of the potential treasure?

You can assume that all units below represent 1 pixel on the map

Note: not only does this challenge require programming ability, but also a certain amount of problem-solving/"detective" logic - if you were a real person on a treasure hunt/spy/police officer etc, you wouldn't be told exactly what to do - you may have access to limited data and you would have to use your own intuition to solve the rest

If you have no idea where to start, hints will be released after 24 hours - but I'm curious (and would be impressed) if anyone is able to solve it without any hints!

Hints

Hints will be released at the start of each of the following days - e.g. the start of day 3 is 48 hours after the challenge starts

Release Day Hint
2 As you walk around, you notice the last two values on the device are changing - they seem to be the current co-ordinates (i.e. of the body on the ship). Based on these co-ordinates, it will be useful to figure out the map's origin (i.e. 0, 0) position (is the top lef, is it the bottom left, is it the middle etc)
3 They say a picture speaks a 1000 words - perhaps downloading the map and visually plotting the path on the image using a graphics library/API in your chosen programming language might be useful
4 Remember, you need to backtrack through the pirate's steps - think carefully about which direction you will be looping through the data
5 Since the device records movements in chronological order, if you backtrack, you will need to move in the opposite direction - for example, if the pirate moved 5 pixels south, you will need to move 5 pixels north to get to the position they came from
6 Burying treasure takes time
7 To make it easier for themselves to find the correct spot in the future, the pirate conveniently decided to walk in a nice 'X' at the location of the treasure
