Fable did that, I pretty much just told it to find the best Fourier sum which can draw a map of the world in less than 500 bytes of R. It downloaded geo data and made the curves to fit that on its own.
Can you post the unencode version? It would be nice to see the vector with the data, for example to count how many coefficients each continent got.
Have you tried with Bezier curves? Your images show a lot of pointy parts, like Southeast Asia and that usually needs a lot of high frequencies in the Fourier representation, so I think something piecewise may be better. (Perhaps a polygon is better.)
