WorldAtlas features a political map that shows continents, countries and territories along with the location of some major cities and governmental boundaries demarcating states within countries. Maps of World has a map that features the agreed-upon boundaries of all 193 United Nations member states, as well as several contested borders and the physical locations of the two U.N. observer states. The political map at Geology.com uses the Mercator projection to show geographic features of the Earth along with national boundaries.
Although the U.N. recognizes 195 countries, it is difficult to fit the names of many tiny states, such as Vatican City, Andorra and San Marino, onto traditional political maps because of a general lack of space. Many political maps circumvent this issue by correctly drawing the international boundaries and national divisions and labeling small countries with a number that users can look up in an index.
Educational website Sheppard Software has exercises and geography games that allow users to locate countries, capitals, regions and landscapes on unmarked maps. Sheppard has games and quizzes that pertain to national boundaries in Asia, North America, Europe, Africa and the Middle East as well as the Caribbean and Oceania. It also has geography games for users who wish to learn about the locations of Canadian provinces and Mexican and American states.
