It's weird that it mentions the Sea of Cádiz, but not Cádiz City. Instead: Vejer ("Beger") Tarifa ("Terifa") and Gibraltar ("Zibelter"). The cities far from the coast are randomly placed. Actually, Mediterranean Sea seems mostly accurate and anything else gets deformed, more so as distance increases. See Africa.

portolan charts[0] were already common by the time this map was made, so coastal regions, especially in the mediterranean, were better documented.
