Portuguese craftsmen such as Agostinho de Goes Raposo, Francisco Gois and Joao Dias perfected the construction of nautical instruments. The Portuguese caravel - and its successors the great nau (1480) and the galleon (1510) - were also significantly better than other sailing ships of the time. Finally, with the Cantino Map of 1502, the Portuguese achieved a breakthrough in cartography: the first modern projection of the world's geography, with largely accurate depictions of the world's major continents aside from Australia and Antarctica (plate 7).
