How do Mercator and Robinson maps distort the Earth?
Mercator is used for navigation or maps of equatorial regions.
Distortion increases away from the equator and is extreme in polar regions (Greenland appears larger than Africa but is actually 14 times smaller).
Parallels and meridians are straight lines which meet at right angles..
What are the pros and cons of a Peters Projection?
Advantages: On Peters’s projection, […], areas of equal size on the globe are also equally sized on the map. Disadvantages: Peters’s chosen projection suffers extreme distortion in the polar regions, as any cylindrical projection must, and its distortion along the equator is considerable.
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.
Why is Mercator still important today?
Because of the preserved 90° angles and straight lines of latitude and longitude, rhumb lines are also straight on the Mercator projection. … Due to this, the Mercator projection made world exploration much easier and became a essential map projection for navigation.
Why do many geographers prefer the Robinson projection?
Geographers prefer the Robinson Projection because it shows the size and shape of most of the land quite accurately. The sizes of the oceans and and distances were also very accurate.
Which projection does National Geographic use now?
In 1998, the Winkel tripel projection replaced the Robinson projection as the standard projection for world maps made by the National Geographic Society. Many educational institutes and textbooks followed National Geographic’s example in adopting the projection, and most of those still use it.
What are the advantages of the Robinson projection?
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 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 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.
Why is the Mercator 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.
Is Russia bigger than Africa?
At 6.6 million sq. mi (17 million km2), Russia is the world’s largest country. … Drag and drop it near the equator, and you see how truly huge Africa is: at 11.73 million sq. mi (30.37 million km2), it is almost twice the size of Russia.
What are the advantages and disadvantages of a 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.
Why is Africa 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.
Does Mercator preserve shape?
Mercator is a conformal map projection. Directions, angles, and shapes are maintained at infinitesimal scale. Any straight line drawn on this projection represents an actual compass bearing. These true direction lines are rhumb lines and generally do not describe the shortest distance between points.
Is Alaska bigger than Mexico?
Alaska is appears to be three times larger than Mexico, although Mexico actually is larger than Alaska. On a Mercator map, Greenland looks larger than China, even though China actually is four times larger than Greenland.
Is Mercator projection accurate?
This is much smaller than the scale inaccuracy, except very close to the equator. Only accurate Mercator projections of regions near the equator will necessitate the ellipsoidal corrections.
What is the Mercator projection best used for?
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.
What is the difference between Mercator and Robinson projection?
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 are the 4 map projections?
This group of map projections can be classified into three types: Gnomonic projection, Stereographic projection and Orthographic projection.Gnomonic projection. The Gnomonic projection has its origin of light at the center of the globe. … Stereographic projection. … Orthographic projection.
Is Greenland bigger than the US?
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.
