Administrative structure and maps

Unlike physical maps, socio-economic maps show the location of settlements, mineral deposits, industrial centres, farming and routes. Data are given by the dot, cartodiagram and cartogram methods. In a cartogram, areas are coloured or shaded by an indicator (for example, population density); in a cartodiagram, a bar or circle is drawn over each area. By theme, maps are population, industry, agriculture, transport, services, recreation and foreign economic relations maps. When reading a map, first look at its title and legend. Today electronic maps (such as online maps and GPS programs) are widely used alongside printed ones: they show location, photographs and the shortest route.
