A map is a representation of the earth's surface or part of it, using symbols, numbers, colors, or lines to show information about location, distance, height, or geographic features such as mountains, rivers, cities, or borders. Maps are designed to help humans understand and navigate by reducing the size of the real world down to a manageable format.
Maps not only display physical data, but can also display abstract information such as population distribution, temperature, or economic data, depending on the purpose of use. In addition, maps play important roles such as military, political, educational, and urban planning.
