What is the definition of a map?

A map is defined as a line drawing of a portion of the Earth's surface, drawn to scale as seen from above. This definition captures the essential characteristics of a map: it is a two-dimensional representation that accurately depicts features of a specific area, allowing users to discern distances and relationships between different geographical elements.

Maps are created through a process called cartography, where the surface of the Earth is projected onto a flat medium while maintaining essential details such as scale, orientation, and symbols. This allows individuals to navigate, understand, and interpret various locations, whether for travel, study, or urban planning.

The other options, while related to geographical representations, do not encapsulate the core definition of a map as effectively. For instance, a three-dimensional representation, such as a globe, differs in its dimensionality and function from a traditional map. A geographical description lacks the visual and scaled depiction that maps provide, which is crucial for numerical and analytical understanding. Lastly, an abstract rendition of topography may involve artistic interpretations rather than the precise, standardized format and practicality expected from a map.
