A map is an image of an area, usually of the Earth or part of the Earth. A map is different from an aerial photograph because it includes interpretation.
The word “map” can also be used to talk about a chart or drawing that shows relationships between ideas, people, events, or anything else you can think about. This is why web developers call a list of web pages on a web site a site map.
People who make maps are cartographers.
The only kind of map of the Earth that is not projected flat is one drawn on a sphere. This is called a globe.
