Quick Answer: What Is The Difference Between Mercator And Robinson Projection?

Is Greenland larger than USA?

United States is about 4.5 times bigger than Greenland.

Greenland is approximately 2,166,086 sq km, while United States is approximately 9,833,517 sq km, making United States 354% larger than Greenland.

This to-scale map shows a size comparison of Greenland compared to United States..

What are the advantages and disadvantages of the Mercator projection?

Advantage: The Mercator map projection shows the correct shapes of the continents and directions accurately. Disadvantage: The Mercator map projection does not show true distances or sizes of continents, especially near the north and south poles.

What is wrong with the Robinson projection?

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 does Robinson map mean?

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. … Robinson published details of the projection’s construction in 1974.

What are the 4 types of map projections?

Types of Map ProjectionsGnomonic projection. The Gnomonic projection has its origin of light at the center of the globe. Less than half of the sphere can be projected onto a finite map. … Stereographic projection. The Stereographic projection has its origin of light on the globe surface opposite to the tangent point. … Orthographic projection.

Why is the Mercator projection map still in use today?

Why is the Mercator projection map still in use today? It is useful to sailors because, although size and shape are distorted, it shows directions accurately. … Mercator projections help sailors to navigate.

What is 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.

Which map projection is the most accurate?

AuthaGraphAuthaGraph. 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.

What are the 5 map projections?

Top 10 World Map ProjectionsMercator. This projection was developed by Gerardus Mercator back in 1569 for navigational purposes. … Robinson. This map is known as a ‘compromise’, it shows neither the shape or land mass of countries correct. … Dymaxion Map. … Gall-Peters. … Sinu-Mollweide. … Goode’s Homolosine. … AuthaGraph. … Hobo-Dyer.More items…•

Who uses Peters Projection?

Maps not only represent the world, they shape the way we see it. The revolutionary Peters Projection map presents countries in their true proportion to one another: it has been adopted by the UN, aid agencies, schools and businesses around the world.

What is the Robinson projection most useful for?

The Robinson projection is unique. Its primary purpose is to create visually appealing maps of the entire world. It is a compromise projection; it does not eliminate any type of distortion, but it keeps the levels of all types of distortion relatively low over most of the map.

What is the difference between the Mercator and Peters Projection?

In addition, Mercator only distorts longitudinal distances (except very close to the poles), whereas Peters screws up the scale almost everywhere for both longitude and latitude. This is why Mercator beats out Peters in the world of cartography, and why Google Maps uses a modified Mercator projection.

What is meant by Mercator projection?

Mercator projection, type of map projection introduced in 1569 by Gerardus Mercator. … This projection is widely used for navigation charts, because any straight line on a Mercator projection map is a line of constant true bearing that enables a navigator to plot a straight-line course.

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.

Why does Africa look smaller on maps?

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.
