The Art of American Cartography

Living on Earth
A prize-winning map tells the story of the United States as never before. Map-maker Dave Imus spent 6000 hours creating a depiction of America that is much art as it is cartography. He explains to host Bruce Gellerman why it takes a big sheet of paper to understand the beauty and vastness of this country. Then we celebrate National Poetry Month with a poem from Walt Whitman that celebrates America and its varied voices.
