Quick Answer: What Are The Disadvantages Of The Robinson Projection?

What is one disadvantage 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 the Mercator 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 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.

Why do cartographers need to use projections when drawing maps?

The larger the area covered by a map, the greater the distortion. … Depending on the map’s purpose, cartographers must decide what elements of accuracy are most important to preserve. This determines which projection to use. For example, conformal maps show true shapes of small areas but distort size.

What map projection has the least distortion?

The only ‘projection’ which has all features with no distortion is a globe. 1° x 1° latitude and longitude is almost a square, while the same ‘block’ near the poles is almost a triangle.

Which projection does National Geographic use now?

Mollweide projectionCartographers at National Geographic chose to use a version of the Mollweide projection for their map highlighting ocean floors, published as the map supplement in the September 2012 issue of National Geographic magazine. This Mollweide projection is referred to as a pseudocylindrical projection.

What are the advantages and disadvantages of a 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.

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.

What is Robinson projection used for?

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. The Robinson projection was devised by Arthur H.

What is one advantage of a Mercator projection?

One advantage of using the Mercator projection is that there are parallels and meridians to cross one another at right angles, just as they do on the globe. As a result, the direction is true everywhere on his map, a very important fact for anyone traveling east to west, or vice versa, on the Atlantic.

How do maps help focus the reader’s attention on just a few specific things?

c) How do maps help focus the reader’s attention on just a few specific things? ANSWER: They help do this by containing a limited number of elements. 6. … They are used for everyday pur- poses like finding the location of a store on a city map or planning a canoe trip in a large provincial park.

What are the weaknesses of the Robinson projection?

Robinson projections are not equivalent; they do suffer from compression. However, the amount of area distortion is generally low within about 45° of the equator. Conformality: The Robinson projection is not conformal; shapes are distorted more than they would be in a truly conformal projection.

Why is Mercator projection bad?

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.

What are the advantages and disadvantages of conic projection?

Lambert Conformal Conic Projection Map Properties The major advantage of the Lambert Conformal Conic map projection is how it retains conformality. Despite how distances are reasonable accurate and retained along standard parallels, it isn’t equal-area as distortion increases away from standard parallels.

What are the advantages and disadvantages of the three main map projections?

What are the advantages and disadvantages of the three main map projections? The advantages of a cylindrical map is that it shows accurate direction and shapes. The disadvantage is that it enlarges and distorts by exaggeration of size.

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.

Which world map is most accurate?

AuthaGraphView the world in correct proportions with this map. You may not know this, but the world map you’ve been using since, say, kindergarten, is pretty wonky. The Mercator projection map is the most popular, but it is also riddled with inaccuracies.

What are the advantages and disadvantages of azimuthal projection?

List of the Disadvantages of Azimuthal ProjectionIt applies well when looking from a polar perspective only. … A perspective azimuthal projection cannot plot out the entire Earth. … Distortions increase as the distance expands on the map. … It creates an awkward perspective when used for centering purposes.More items…•
