Question: How Do Mercator And Robinson Maps Distort The Earth?

How does a Mercator map distort the world?

Conformal projections preserve angles around all locations.

Because the linear scale of a Mercator map increases with latitude, it distorts the size of geographical objects far from the equator and conveys a distorted perception of the overall geometry of the planet..

Where does a Mercator distort land forms the most?

The Mercator projection distorts a continents SIZE. The landforms near the North Pole and South Pole have more distortions than the landforms near the equator.

What are the 4 ways maps get distorted?

There are four basic characteristics of a map that are distorted to some degree, depending on the map projection used. These characteristics include distance, direction, shape, and area.

Why do all map projections have distortion?

Because you can’t display 3D surfaces perfectly in two dimensions, distortions always occur. For example, map projections distort distance, direction, scale, and area. Every projection has strengths and weaknesses.

Why is Robinson better than Mercator?

Unlike the Mercator projection, the Robinson projection has both the lines of altitude and longitude evenly spaced across the map. … In opting for a more pleasing appearance, the Robinson projection ‘traded’ off distortions – this projection is neither conformal, equal-area, equidistant nor true direction.

What is the major weakness of the Mercator projection?

Disadvantages: Mercator projection distorts the size of objects as the latitude increases from the Equator to the poles, where the scale becomes infinite. So, for example, Greenland and Antarctica appear much larger relative to land masses near the equator than they actually are.

What map projection is most accurate?

AuthaGraph. This is hands-down the most accurate map projection in existence. In fact, AuthaGraph World Map is so proportionally perfect, it magically folds it into a three-dimensional globe. Japanese architect Hajime Narukawa invented this projection in 1999 by equally dividing a spherical surface into 96 triangles.

Why is Africa smaller on the map?

It’s all down to the European cartographer Geert de Kremer, better known as Mercator, and his 16th century map projection — a common template for world maps today — which distorts the size of countries.

Why do maps show Greenland so big?

However, Greenland looks bigger than China because it is close to the North Pole and China being closer to the equator.

What map has the least distortion?

On the other hand, one kind of projection that doesn’t distort area is the Cylindrical Equal Area. Notice here how Greenland looks the right size as compared to South America. Projections which preserve areas are called equivalent or equal-area projections.

What is the purpose of the Robinson map?

The Robinson projection is a map projection of a world map which shows the entire world at once. It was specifically created in an attempt to find a good compromise to the problem of readily showing the whole globe as a flat image.

What does the Robinson map distort?

The Robinson projection is neither conformal nor equal-area. It generally distorts shapes, areas, distances, directions, and angles. The distortion patterns are similar to common compromise pseudocylindrical projections. Area distortion grows with latitude and does not change with longitude.

What is the disadvantage of the Robinson projection?

Advantage: The Robinson map projection shows most distances, sizes and shapes accurately. Disadvantage: The Robinson map does have some distortion around the poles and edges.

What’s wrong with the Mercator projection?

Mercator maps distort the shape and relative size of continents, particularly near the poles. This is why Greenland appears to be similar in size to all of South America on Mercator maps, when in fact South America is more than eight times larger than Greenland.

Why is every world map wrong?

The distortion is the result of the Mercator projection, the map most commonly seen hanging in classrooms and in text books, which was created in 1596 to help sailors navigate the world.
