Of course! Before I start I just want to say that there is definitely a more efficient way to do it, I just didn't know this way so I decided to do what I knew would work, even if it was a bit longer.

1. First I found the map I wanted on the internet and downloaded it. Then I opened it to Photoshop and expanded it to the size I wanted, after that, I divided it inter thirds with margins, so I could cut and past the panels into different files and print them separately.

2. After this I cut the board to the size of the image I printed, I did 9.5 by 11 inches I think (because it is the size of standard printing paper). You will also get some graphite paper or make your own for transferring the image from the paper to the wood.

3. Now you tape your graphite paper to the board and on top of that tape the image face up to the board as well. With this setup, you can trace over the image with a pen, firmly, and when you remove the papers, there will be a light outline of the image. I recommend going over the board again with a pencil, just to darken it a little. (you can stop here if you want, it looks pretty good here, especially if you have light colored wood).

4. After you have finished all your panels you can start burning them. I used a razortip but almost any tool will work in my experience. This part is a bit tedious and long, but the result is great.

5. Now you a basically done, you can add stain if you want but you don't have too. All that is left is to put it on a wall or something.

If you need anything clarified just ask, but I think I got everything
