Somehow there are thousands of Wikipedia pages that use maps in this specific style to show the location of any kind of place imaginable. They clearly are all segments taken from some original source. But I am completely unable to determine that source.

Given the staggering number of pages on which these maps appear, the source surely must be publicly accessible, but I am absolutely unable to find it.
