NATIONAL GEOGRAPHIC CARTOGRAPHERS bring nearly a century of mapmaking experience and cutting-edge technology to bear on every atlas product. Over the last decade, techniques used in digital mapping have undergone remarkable changes. Today, satellite and digital imaging technologies provide cartographers with new tools to map and animate Earth and its myriad regions. Leveraging these emerging technologies to build smart, well-designed, functional, informative atlases is one of the great strengths of National Geographic.
