An updated edition of the classic, much praised history of cartography. It traces the adventures, discoveries, and feats of technical ingenuity by which mapmakers, over the centuries, have succeeded in charting first the surface of the globe, then the earth's interior and the ocean floors, and finally the moon and the planets of our solar system. The author has added three new chapters, as well as many updates and amplifications, to reflect the great changes that have taken place in mapmaking in the past two decades. The Mapmakers will continue to be the definitive book on this fascinating subject.
