The Penn State University Libraries no longer maintains Digital Chart of the World (DCW); however, an archived version and alternate alternative products are available below.
The Digital Chart of the World is a comprehensive 1:1,000,000 scale vector basemap of the world, which was originally created from U.S. Defense Mapping Agency (DMA) data of aeronautical charts. Thematic layers include roads, populated places, land cover, and vegetation.
