## 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 are the disadvantages of a Robinson map?

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.

## 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 is a weakness of the Equal Area 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 is the azimuthal projection used for?

The azimuthal equidistant projection preserves both distance and direction from the central point. The world is projected onto a flat surface from any point on the globe.

## What are the disadvantages of planar projection?

Disadvantages: -The direction and areas are only accurate in relationship to the central point. -It takes several flat projections to depict the entire earth. Description: Equal-area projections accurately depict the area of all regions of the earth at one time.

## What does azimuthal projection mean?

azimuthal projection. A map projection in which a globe, as of the Earth, is assumed to rest on a flat surface onto which its features are projected. An azimuthal projection produces a circular map with a chosen point-the point on the globe that is tangent to the flat surface-at its center.

## Which is the best map projection?

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…•

## What is a planar projection map most useful for?

Planar projections are used most often to map polar regions. Some planar projections view surface data from a specific point in space. The point of view determines how the spherical data is projected onto the flat surface. … The orthographic projection views the earth from an infinite point, as if from deep space.

## What are the advantages and disadvantages 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 are the advantages and disadvantages of a conic map 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 is a Gnomonic projection used for?

Gnomonic projections are used in seismic work because seismic waves tend to travel along great circles. They are also used by navies in plotting direction finding bearings, since radio signals travel along great circles.
