What Four Things Do Map Projections Distort?

What is the main drawback of Goode’s interrupted projection?

In 1923, J.

Paul Goode merged the Mollweide (Homolographic) projection and the Sinusoidal projection to create Goode’s Homolosine Interrupted.

The advantage of this projection is each of the continents are the correct size and in proportion to one another.

The disadvantage is distance and direction are not accurate..

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…•

What causes map distortion?

A map projection is a mathematical formula used to transfer all or part of the curved surface of the earth onto the flat surface of a map. The process of flattening the earth causes distortions in one or more of the following spatial properties: Distance. Area.

What are the 3 main map projections?

Three of these common types of map projections are cylindrical, conic, and azimuthal.

What are four types of distortion?

There are four basic characteristics of a map that are distorted to some degree, depending on the map projection used. These characteristics include distance, direction, shape, and area.

What is the Robinson projection good 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.

Who invented the first globe?

Martin BehaimCrates of Mallus is said to have made one in about 150 bce. The earliest surviving terrestrial globe was made in Nürnberg in 1492 by Martin Behaim, who almost undoubtedly influenced Christopher Columbus to attempt to sail west to the Orient.

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.

What is a map distortion?

If a map preserves shape, then feature outlines (like country boundaries) look the same on the map as they do on the earth. … A conformal map distorts area—most features are depicted too large or too small. The amount of distortion, however, is regular along some lines in the map.

What map projection has the most distortion?

In most maps, when you try to fix one kind of distortion, you increase another kind of distortion. However, Mercator is one of those rare maps whose answer to latitudinal distortion was to ensure that the longitudinal distortion is equally bad! On a Mercator projection, Greenland is roughly the same size as Africa.

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.

Why does map distortion occur?

Because you can’t display 3D surfaces perfectly in two dimensions, distortions always occur. For example, map projections distort distance, direction, scale, and area. Every projection has strengths and weaknesses. All in all, it is up to the cartographer to determine what projection is most favorable for its purpose.

What does the Mercator projection distort?

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.

Which map projection has no 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.

What are the four types of distortion on flat maps quizlet?

What are the four types of distortion on flat maps? area, shape, distance, and direction.
