I can't help but think that the map seems a bit too symmetrical, particularly with the resources.
(both screenshot(or can't i say the screenshot is CC0 because it shows annex?)
Based solely on my knowledge of Wikipedia's policies regarding screenshots of software, I'm under the impression that screenshots tend to fall under the same licensing of the source, unless there is no copyrightable objects visible (which is not the case here). Since the screenshot uses almost entirely Annex media, I'd presume that it would fall under Annex's license, namely CC-BY-SA, meaning that it would also require credit to Ishmaru.
