- A world map is a map of most or all of the surface of Earth. World maps, because of their scale, must deal with the problem of projection. Maps rendered in two dimensions by necessity distort the display of the three-dimensional surface of the Earth. While this is true of any map, these distortions reach extremes in a world map.

Jan 15, 2022 · Though designed with the best of intentions — to provide a detailed and coherent projection of Earth — flat maps are far from accurate; some areas look far bigger than they really are, others...

North is up, right? Only by convention. There’s no scientific reason why north is any more up than south. Equally, we could do east-up, west-up or any other compass bearing. Purposefully reversing the typical way world maps are drawn has a similar political effect to using the Peters projection, putting more developing countries in the generally po...
Another convention of world maps is that they are centred on the prime meridian, or zero degrees longitude (east-west). But this is scientifically arbitrary, deriving from the location of the Royal Observatory in Greenwich, London. The result is that Europe (although also Africa) is in the centre of the conventional world map – a rather colonial pe...
All the projections we’ve discussed so far tend to put one continent in the middle of the map, giving it greater prominence over the others. An alternative is to place the North Pole in the centre. It is strangely disorienting to gaze on the world from a polar perspective. The lower hemisphere should be hidden from view by the curve of the Earth be...
Another way of representing the world is to display countries’ sizes in proportion to key indicators of interest to geographers today, such as population, environment and development. Predictably, the world map of GDP is dominated by North America and Europe, while Africa almost disappears. The population cartogram gives greater prominence to India...

May 3, 2024 · World maps usually show political features, such as country borders, and physical features. World maps can also be used to present data on average temperature, soil type, rainfall distribution, and much else. Because Earth is an ellipsoid, a world map, which presents Earth in two dimensions, is necessarily a distorted representation.

Mar 8, 2022 · Some world maps are designed to preserve the shape of countries (called Lambert Conformal Conic projections ), whereas other maps – those globes that bulge at the equator – preserve area; these are Mollweide projections.
