Map features:

1. Quantifiability resulting from special mathematical laws. Special mathematical laws contain three aspects of map projection, map scale and map orientation.

2, by the use of map language to represent things produced by the intuitive. The map represents a variety of complex natural and human things are realized through the map language. Map language includes map symbols and map notes two parts.

3, by the implementation of the cartographic synthesis produced by the glance.

4, the map must follow certain mathematical laws.

The map is drawn on the plane, must accurately reflect the relationship between it and the objective entity in the location, attributes and other elements.

5, the map must be scientifically generalized.

Shrunken maps cannot possibly accommodate all phenomena on the ground.

6, the map has a complete symbol system.

The object of the map is mainly the Earth. The earth has an extremely large number of geographic information, including natural and socio-economic phenomena. Only through a complete symbol system, can accurately express this phenomenon.

7, the map is the carrier of geographic information.

The map accommodates and stores a huge amount of information, and as the carrier of information, can be the traditional concept of paper maps, physical models, can be a variety of visualization screen images, audio-visual maps, but also tactile maps.
