What happens when a globe is flattened into a map?
When you look at it in any direction, you won’t be able to see all sides of it. But when you peel the orange, flatten and stretch it out, you can begin to see everything. Similarly, a map projection is a method by which cartographers translates a sphere or globe into a two-dimensional representation.
Why can’t a flat map present the world accurately?
Whenever you glance at a flat world map, you should take what you see with a grain of salt. One in particular, known as the Mercator projection, distorts the actual sizes of landmasses like Alaska and Greenland and makes them appear larger in comparison to Africa or North America than they are.
How do you flatten a spherical world onto paper?
How do you flatten a spherical world onto paper?…Many methods of depicting relief have been used, including:
- Hachures: A short line on a map that indicates the direction of slope.
- Hill-shading: Shadows drawn on the map to create a three-dimensional effect.
- Contours: A line on a map that connects points of equal height.
How is making a map of Earth like trying to flatten an orange peel?
There are two basic methods that the mapmaker uses in projections:
- The mapmaker “slices” the sphere in some way and unfolds it to make a flat map. This is like flattening out an orange peel.
- The mapmaker can look at the sphere from a certain point and then translate this view onto a flat paper.
What are the four types of projections?
Types of Map Projections
- Gnomonic projection. The Gnomonic projection has its origin of light at the center of the globe.
- Stereographic projection. The Stereographic projection has its origin of light on the globe surface opposite to the tangent point.
- Orthographic projection.
What are the 4 common map projections?
Introduction
| Projection | Type | Key virtues |
|---|---|---|
| Stereographic | azimuthal | conformal |
| Lambert Conformal Conic | conic | conformal |
| Mercator | cylindrical | conformal and true direction |
| Robinson | pseudo-cylindrical | all attributes are distorted to create a ‘more pleasant’ appearance |
What is the best map of the Earth?
We found that the best previously known flat map projection for the globe is the Winkel tripel used by the National Geographic Society, with an error score of 4.563. It has straight pole lines top and bottom with bulging left and right margins marking its 180 degree boundary cut in the middle of the Pacific.

What is wrong with the gall Peters Projection?
Despite these benefits, the Gall-Peters projection has its flaws. It doesn’t enlarge areas as much as the Mercator projection, but certain places appear stretched, horizontally near the poles and vertically near the Equator.
What is better a map or globe?
When talking of accuracy, a globe is more accurate than the map. A map presents the physical features of a particular region of the earth on a plane surface. A globe can be called as a duplicate earth. It is round in shape and shows accurate areas, distances, directions and relative shape and size.
Is Alaska bigger than Mexico?
Alaska is about 1.3 times smaller than Mexico. Mexico is approximately 1,964,375 sq km, while Alaska is approximately 1,481,348 sq km, making Alaska 75.41% the size of Mexico.
Why are maps wrong?
Locations aren’t the only way our mental maps can be wrong; we also have misconceptions about the relative size of things. This may be due in part to the nature of two-dimensional maps. Mercator maps distort the shape and relative size of continents, particularly near the poles.
Why does Africa look so small on maps?
The world map you are probably familiar with is called the Mercator projection (below), which was developed all the way back in 1569 and greatly distorts the relative areas of land masses. It makes Africa look tiny, and Greenland and Russia appear huge.
