If you want to read about the early, pre-1400, development of longitude and latitude positioning using lunar observations pick up a copy of "1434" by Gavin Menzies. Much research is discussed into the contribution of Toscanelli, Alberti, and Regiomontanusee. These early mathematicians shook up the Greek "flat earth" and the earth is at the center of the universe crowd.
