Flinders Island
It was time that I tried my hand at an island map, and something outside of the United States. Luckily, I found a new source for heightmaps that is easy to use, and I want to share it and credit it here: cs.heightmap.skydark.pl/
After searching the seven seas, morcup discovered the perfect island, Flinders Island, off of the north shore of Tasmania. It has all of the resources, and plenty of flat land. Most of the eastern shore is suitable for ship activities. The western shore is a bit steeper on average, but still has a few natural harbors.
This map features no border connections, and no infrastructure.
