 The 1568 atlas contains the first large-scale charts of Ceylon (Sri Lanka) and Japan, later copied by many other cartographers.His chart of the northwestern coast of Africa, displayed above is executed using the so-called "plain chart model", where observed latitudes and magnetic directions were plotted directly into the plane, with a constant scale, as if the Earth were flat.Until the adoption of the Mercator projection charting method, this was the most advanced charting method in Europe.
