One of the earliest types of world map is the so called "T and O map" (Swedish: T-Karta), originating during the middle ages. The name comes from the shape and form of the map, the 'T' representing the Mediterranean sea and the Nile and Don rivers. These waters separate the three continents Asia, Europe and Africa, and around them is a circular 'O' representing the surrounding ocean. It was not considered necessary to include the southern hemisphere because it was believed uninhabitied and even unreachable.
Nowadays with the advances of digital cartography, maps can be made using special technology (GIS or Grographic Information Systems) for sourcing geographic information, compiling this into a digital storage or 'geographic database', producing a map composition with the desired symbol styling, and distributing the map both in traditional printed format, and digitally on live displays, via the Internet and using touchscreens and smartphones.
Maps are often used for navigation, showing you how to get from one place to another, using different modes of transportation.
Navigation can be on foot, by bicycle, using public transport. Or even travelling by boat or flying. The map is designed such that the information it contains is relevant and useful to the purpose of the map.
Maps can be packed with information, or can be simple and stylistic.
A well designed map can be a beautiful work of art.
