What is a map

A map is a type of information map that represents the Earth or other planets in a flat format. It is a graphic tool made by people to understand, express, manage, and utilize geographic information on the Earth or other planets. Maps can reflect all aspects of geographic information on the Earth or other planets such as topography, landforms, natural resources, climate, transportation, economy, culture and so on. Using maps, we can better understand the world, grasp the direction, plan travel routes, conduct geoscientific research, and even used in military operations and emergency rescue and other fields. Modern maps can be displayed and interacted online through computer and network technology, providing great convenience for our travel, tourism, study and work.
