The sinusoidal projection is used between those two latitude values for the equatorial part of the world. The projection shows discontinuity in the graticule where both projections join. The Goode homolosine projection was introduced by J. Paul Goode in 1923.
Who made 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 was the Goode projection created?
The projection was developed in 1923 by John Paul Goode to provide an alternative to the Mercator projection for portraying global areal relationships . Goode offered variations of the interruption scheme for emphasizing the world’s land and the world’s oceans.
What is the purpose of Goode Homolosine projection?
Description. Goode’s homolosine map projection is designed to minimize distortion for the entire world . It is an interrupted pseudocylindrical equal-area projection. John Paul Goode developed the projection in 1925.
What are the disadvantages of the Goode Homolosine projection?
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 is wrong with the Robinson projection?
The Robinson projection is neither conformal nor equal-area. It generally distorts shapes, areas, distances, directions, and angles . ... Angular distortion is moderate near the center of the map and increases toward the edges. Distortion values are symmetric across the equator and the central meridian.
What is wrong with the Goode projection?
Goode homolosine is an equal-area (equivalent) projection. Shapes, directions, angles, and distances are generally distorted . ... There is no distortion along the central meridians and the equator. In the uninterrupted form, bulging meridians produce considerable shape distortion toward the edge of the projection.
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 the most accurate map projection?
The lower the score, the smaller the errors and the better the map. A globe of the Earth would have an error score of 0.0. We found that the best previously known flat map projection for the globe is the Winkel tripel used by the National Geographic Society, with an error score of 4.563.
What is Robinson projection used 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.
What are the pros and cons 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. Who uses it? The Robinson is most commonly used by students, teachers, textbooks and atlases.
Who uses the Robinson projection?
Robinson Projection
Robinson in 1961 and was indeed to make world maps “look right” rather than measure precisely. This now common projection and has been used in many popular maps such as the Rand McNally series (from the 1960s) and the National Geographic Society (since 1988).
How are Gnomonic projections made?
In a gnomonic projection, great circles are mapped to straight lines. The gnomonic projection represents the image formed by a spherical lens , and is sometimes known as the rectilinear projection. and the two-argument form of the inverse tangent function is best used for this computation.
Who uses equal area projection?
The USGS commonly uses the Albers Equal Area Conic projection because of how it proportionally represents areas for the conterminous United States. Like all map projections, the Albers Equal Area Conic Projection distorts other properties in a map.
What are the pros and cons of using a conical map projection?
Conical Projections: Pros: These maps are very good for mapping regions that are primarily West-East in dimension like the United States . That is because a cone, when developed, is itself wider than tall. Cons: The basic con is that a single cone cannot show the entire globe.
What are the pros and cons of map 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.
