Natural Earth
Natural Earth is a public domain map dataset available at 1:10 million (1 cm = 100 km), 1:50 million, and 1:110 million map scales. Natural Earth's data set contains integrated vector and raster mapping data.
The original authors of the map dataset are Tom Patterson and Nathaniel Vaughn Kelso, but Natural Earth has expanded to be a collaboration of many volunteers and is supported by the North American Cartographic Information Society (NACIS). It is free for public use in any type of project.
