Processing this map took longer than I expected because it was divided into 10,710 tiles of 256×256 pixels each. I had to write a JS script to fetch all of these tiles and stitch them into larger tiles of 7,680×7,680-pixel images before combining then cropping them using GIMP into the final 22,860×30,116-pixel behemoth. I ran into various memory limitations because Firefox and GIMP had trouble working with these huge images.
