“Geography and maps are a fundamental language for understanding the world. They provide a framework for organizing and communicating our knowledge. Increasingly geography is used in virtually every field of human endeavor, providing a universal language for understanding, communicating ideas, and providing insights. Geography asks the big questions—Where? How? Why? What if?—and gives you the perspective to answer them with advanced technology and a solid knowledge of the world in which we all live.”
