The illustrator seems to have used distinct "ornamental" patterns for certain terrestrial phenomena, such as mountains, water, wind etc. (By the way, it would be quite useful to create a "catalogue" of these ornaments for an easy reference).
So in the first place we need to ascertain what these particular ornaments (on either side of the "road") are meant to represent in general. Then, guided by the alleged placement of continents on this alleged map, we can derive the continents in question. And then we can make conclusions about specificity of these very instances of this ornamental pattern.
