Picture of the day
A pre-
Mercator
nautical chart
of
West Africa
from 1571, by
Portuguese
cartographer
Fernão Vaz Dourado
. It is done using the so-called "plane chart model", where observed
latitudes
and magnetic directions were plotted directly into the plane, with a constant scale, as if the Earth were flat.
