Navigation is tough for me. Thanks to Google maps and help from people, I find my way. Maps are an essential to explorers, travelers, and navigators Cartography is an art and a science both. Even with technology and centuries of exploration, mapmakers today have an easier time creating maps. Imagine the difficulties of a 13th century mapmaker: the seas hadn’t been explored as much; the ports that were not accessible – how would a cartographer depict them on maps; and no availability of modern technology to correctly assess distances, places and points.
