Throughout the first hundred years after the discovery of the New World late in the fifteenth century, determining the location and extent of their overseas domains was a principal preoccupation of the Spanish empire. Not only were terrestrial coordinates vital for navigation, but following the 1494 Treaty of Tordesillas, knowing with certainty the location of newly discovered territories carried significant geo-political implications as well. Further complicating the matter were the technical…
