World map

A world map is a cartographic representation of Earth’s surface on a flat plane, usually showing continents, oceans, and political boundaries.

Updated July 27, 20261 min readCited sources

A world map is a flat cartographic representation of Earth's surface, typically showing continents, oceans, and political boundaries. All flat world maps involve some distortion because Earth is a sphere.

What it is

A world map depicts most or all of Earth on a flat surface. It commonly shows continents, oceans, countries, and physical or political features. It can also present thematic data such as climate, population, or vegetation.

Why projection matters

No flat world map can show the planet without distortion. Different projections preserve area, shape, distance, or direction to varying degrees. The Mercator, Robinson, and other projections each have strengths and weaknesses depending on the intended use.

Modern use

World maps are widely used in education, navigation, journalism, and data visualization. Digital mapping and satellite imagery have improved geographic precision. Political boundaries shown may vary by source; for example, the number of countries listed differs between organizations.

In short

  • All world maps distort size, shape, distance, or direction to some degree.
  • Globes are three-dimensional and avoid flat-map projection distortion.
  • World maps can be political, physical, or thematic.
  • Modern mapping relies on satellite imagery for improved accuracy.
Canadian angle

World maps are widely used in Canadian education, government, media, and travel, and Canadian readers may encounter different country counts or boundary depictions depending on the map source.

Quick questions

What is the world map?
A world map is a flat map of most or all of Earth’s surface, usually showing continents, oceans, countries, and other geographic features.
Who created the first world map?
There is no single universally accepted creator. Ancient examples appeared in Mesopotamia and Greece; later Claudius Ptolemy influenced mapmaking with his work Geography.
What is the most accurate world map?
No single world map is universally the most accurate because different projections preserve different properties. Globes are the most accurate overall three-dimensional representation.
