# What Is The Goode Projection Used For?

What is the Goode projection used for? The Goode homolosine projection (or interrupted Goode homolosine projection) is a pseudocylindrical, equal-area, composite map projection used for world maps. Normally it is presented with multiple interruptions. Its equal-area property makes it useful for presenting spatial distribution of phenomena.

Secondly, What does the Goode projection distort?

Distortion. Goode homolosine is an equal-area (equivalent) projection. Shapes, directions, angles, and distances are generally distorted. In the uninterrupted form, bulging meridians produce considerable shape distortion toward the edge of the projection.

Furthermore, What type of projection is Goode? Goode is an interrupted, equal-area, composite projection composed of 12 regions that form six lobes, each the top section of a Mollweide projection, carefully grafted on to six interior regions along the equator. Provides an effective alternative to portraying global area relationships on the Mercator map.

One may also ask, Is the Goode Homolosine projection accurate?

The scale along all parallels in the sinusoidal part (between +/-40° 44') and the central meridians of the lobes of the projection is accurate.

What is the advantage of an equal-area projection?

The equal-area projection retains the relative size of the area throughout a map. So that means at any given region in a map, an equal-area projection keeps the true size of features.

## Related Question for What Is The Goode Projection Used For?

What is the most accurate map projection to date?

AuthaGraph. 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.

What is sinusoidal projection?

The sinusoidal projection is a pseudocylindrical equal-area projection displaying all parallels and the central meridian at true scale. The sinusoidal projection is also known as the Sanson-Flamsteed and Mercator-Sanson projection after the cartographers who used it. The projection was developed in the 16th century.

Which projection would be best for a map of the South Pole and Antarctica?

A better projection is the polar stereographic projection (EPSG:3031 for the South Pole) which shows the pole in the middle. Distortions get larger the farther you get away from the pole, but below 60° they are not that bad.

What is the gall Peters projection used for?

The Gall–Peters projection is a rectangular map projection that maps all areas such that they have the correct sizes relative to each other. Like any equal-area projection, it achieves this goal by distorting most shapes.

How is the Goode projection made?

The Earth's surface is presented on six lobes, mapped onto the Cartesian plane with appropriate offsets. The lobes join along the Equator. Each lobe is divided into two regions at the parallels ±40° 44' 11.8". Thus, the Goode's projection is formed from 12 separate regions and effectively, 12 separate map projections.

Is the Robinson projection accurate?

The Robinson projection is not conformal; shapes are distorted more than they would be in a truly conformal projection. However, shapes are not distorted very badly within about 45° north or south of the equator or within about 45° of the map's central meridian.

What are the advantages and disadvantages of the Mollweide projection?

It preserves the size of figures, but heavily distorts the shapes when getting nearer to the edge of the map. Mollweide maps are especially used for global maps where its equal-area property helps to display global distributions.

What does the Goode Homolosine projection preserve?

This combination of projections helps to preserve the shape of the land masses and results in a map that has less distortion than an uninterrupted global map.

What is the orange peel problem in cartography?

The Earth's surface is like an orange peel. If one were able to peel an orange in one piece and then try to flatten the peel, cracks and tears would appear. Attempting to “peel” the Earth and then lay that information on a flat surface in a map creates these same open areas.

What is the only map projection that accurately would show a great circle route Why?

The Gnomonic projection (Figure 9-2) is another member of the azimuthal projection family (maps projected to a plane surface that is tangent to the globe at a single point), and it has the distinction of being the only map projection on which any straight line represents a great-circle arc.

What are the pros and cons of an equal area projection?

Advantage: The Equal-Area map projection show the correct sizes of landmasses and continents. Disadvantage: The Equal area map causes the shapes of landmasses to be altered and forced into curves.

Is UTM an equal area projection?

The area distortion is more in conformal maps (TM, UTM) compared to equal-area maps. Therefore, the transformation to equal-area projection is performed in applications in which area data is important [3-5]. There are different kinds of equal-area projections, as can be seen in projection tools of GIS software.

Why do we need map projection?

The need for a map projection mainly arises to have a detailed study of a region, which is not possible to do from a globe. from a globe is nearly impossible because the globe is not a developable surface. In map projection we try to represent a good model of any part of the earth in its true shape and dimension.

Why is Greenland so big on maps?

In Mercator maps, the Earth's surface is projected on a cylinder that surrounds the globe (Fig. 4). The cylinder is then unrolled to produce a flat map that preserves the shapes of landmasses but tends to stretch countries towards the poles. This is why the size of Greenland is exaggerated in many world maps.

Who created world map?

Who created the first map of the world? The Greeks are credited with putting map making on a sound mathematical footing. The earliest Greek known to have made a map of the world was Anaximander. In 6th century BC, he drew a map of the then known world, assuming that the earth was cylindrical.

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. There is no one perfect projection and a map maker must choose the one which best suits their needs.

What is sinusoidal projection used for?

Sinusoidal projection maps present accurate area and distance at every parallel and at the central meridian; distortion increases at the outer meridians and at high latitudes. It is often used in atlases to map Africa and South America.

What is the sinusoid?

sinusoid, irregular tubular space for the passage of blood, taking the place of capillaries and venules in the liver, spleen, and bone marrow. The sinusoids form from branches of the portal vein in the liver and from arterioles (minute arteries) in other organs.

Why do we use Mollweide projection?

Mollweide projection is commonly used in small-scale mapping and thematic maps to illustrate accurate area characteristics. Thus, it is used mainly on maps that require accurate areas as opposed to those requiring accurate shapes and angles. It can also be used to show distributions of global data.

Which projection is most widely used?

Because the Earth is roughly spherical, every flat map distorts our planet one way or another. The most popular version is the Mercator projection, created by Flemish cartographer Gerardus Mercator in 1569.

Which projection is suitable for Antarctica?

The polar projection is an azimuthal projection drawn to show Arctic and Antarctic areas. It is based on a plane perpendicular to the Earth's axis in contact with the North or South Pole. It is limited to 10 or 15 degrees from the poles.

How much larger is Africa than Greenland?

The mind-blowing reality is that the continent is 14.5 times bigger than Greenland. Greenland's true size in relation to Africa.

What are the pros and cons of the 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 is accurate about the gall Peters Projection?

The Gall-Peters projection is widely used in British schools and promoted by the UNESCO. Although politically more correct, it is not without flaws: it distorts the shapes of the continents as a result of two dimensional visualisation of three dimensional landmasses. All maps lie to some extent.

What is the difference between the Mercator and Peters Projection?

The Mercator projection, by comparison, grossly distorts the sizes of the continents – causing the Greenland-is-larger-than-Africa effect – but stays true to their shapes. The Peters projection, by contrast, shows all the continents according to their true sizes, which is apparently fairer.

What does it mean when a map projection distorts the earth?

Map projections and 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.

Who created the interrupted projection?

Buckminster Fuller proposed his "dymaxion" map in 1943, using a modified icosahedral interruption scheme to divide the oceans up in a way that shows the continents in a nearly continuous mass as "one island".

Why is Winkel Tripel better than Mercator?

Differences: The Mercator projection is a more accurate projection than Winkel Tripel, however the poles cannot be represented in Mercator. In Winkel Tripel the latitide and longtitude lines curve as they move away from the Equator and the Prime Meridian. In Mercator the the latitide and longtitude lines stay straight.

Does the Robinson projection preserve direction?

The Robinson projection is neither conformal nor equal-area. It generally distorts shapes, areas, distances, directions, and angles. Area distortion grows with latitude and does not change with longitude.

Is Greenland as large as Africa?

What is Gnomonic projection?

Gnomonic is an azimuthal projection that uses the center of the earth as its perspective point. It projects great circles as straight lines, regardless of the aspect. The projection is not conformal nor is it equal-area.

What is the purpose of the Mollweide projection why is it used in many geography books?

The Mollweide projection is appropriate for small-scale mapping, especially for thematic world maps illustrating area characteristics and analysis requiring accurate areas.

What is wrong with the Mollweide projection?

Mollweide is an equal-area (equivalent) projection. Shapes, directions, angles, and distances are generally distorted. Points 40°44' north and south at the central meridian have zero distortion. The scale is correct along the 40°44' north and south parallels and constant along any given parallel.
