Hammond Map or Hammond World Atlas Corporation is an American map company. It was formerly an operating subsidiary of the Langenscheidt Publishing Group, a major map publisher in the United States, but was sold to Universal Map, an affiliate of Kappa Publishing Group, in 2010. No Hammond Publishing product was sold to Kappa Map Group. Langenscheidt Publishing retained the rights to that product line.
The company was founded in 1900 in Brooklyn, New York by Caleb Stillson Hammond, who had previously headed Rand McNally's New York City office since 1894. It was formally incorporated in 1901 as C. S. Hammond & Co. and moved to Manhattan. It soon relocated to a warehouse in Maplewood, New Jersey that was near Hammond's family home. During its heyday in 1950s and 1960s it was second only to Rand McNally. Until the advent of digital mapping from Google Earth predecessor Keyhole in the mid-2000s, it provided the mapping technology for CNN and Headline News. The company was privately owned by the Hammond family until its assets were acquired by Langenscheidt Publishers Inc. in 1999.
