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 are the pros and cons of using a Mercator map projection?
MercatorPros: Sailors loved it; preserves angles and directions in a small area.Cons: Bad for understanding the real size and shape of continents and countries.Related: After this video you’ll never trust a map again.Pros: The only ‘area-correct’ map of its time; got featured in The West Wing (S2E16)More items…•
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. … Similarly, look at an equatorial country like Egypt (1,002,450 sq km). On a normal global map, it looks almost the same size as a north European country like, say Finland (338,424 sq km).
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. … Each type of map is particularly useful in some capacity. Conic projections are good for small-scale maps such as road maps.
Why do we still use Mercator projection?
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 Africa made to look smaller on maps?
On the Mercator map, Africa – sitting on the equator, reasonably undistorted – is left looking much smaller than it really is. … “If you would take a map projection with equal areas then there is almost no space on the map to display all [these details].”
Is Greenland larger than USA?
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. Meanwhile, the population of Greenland is ~57,616 people (332.6 million more people live in United States). … Greenland using our country comparison tool.
Why does Google Maps use Mercator?
Google Maps mainly uses the Mercator projection because it allows to preserve the angles. At first, Google Maps did not use this projection, and as a consequence in cities at high latitudes, right angles could not be maintained on roads and the like.
What are the 4 types of 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.
How does the Mercator projection work?
Although the linear scale is equal in all directions around any point, thus preserving the angles and the shapes of small objects, the Mercator projection distorts the size of objects as the latitude increases from the equator to the poles, where the scale becomes infinite.
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.
What is the most accurate map of the world?
The AuthaGraph Is The World’s Most Accurate MapYou may not know this, but the world map you’ve been using since, say, kindergarten, is pretty wonky. … Narukawa’s AuthaGraph World Map, which he unveiled in 2016, won the coveted Grand Award of Japan’s Good Design Award competition, beating out over 1,000 entries in a variety of categories.More items…•
