Peters projection world map

Africa, South Asia, and South America all appear much smaller in relation to countries further from the equator. Spherical models are useful for small-scale maps such as world atlases and globes, since the error at that scale is not usually noticeable or important enough to justify using the more complicated ellipsoid.

Great circles passing through the center point are drawn as straight lines. But on the azimuthal polar projection from the north, the southern hemisphere has been pulled into view on the page, with the consequence that Antarctica centrifuges into a doughnut around the edge of the circular map.

A scale factor of 1 indicates actual scale is equal to nominal scale, or no scale distortion at that point on the map. Directions are true from the center point North Pole.

Keep in mind that while some projections use a geometric process, in reality most projections use mathematical equations to transform the coordinates from a globe to a flat surface.

We have been misled by a flawed world map for 500 years

Some projections minimize distortion or preserve some properties at the expense of increasing distortion of others. Measure of scale distortion on map plane can also be quantified by the use of scale factor.

Map Projections - types and distortion patterns

Gnomonic projections map all great circles as straight lines, and such property makes these projections suitable for use in navigation charts. The cone is cut lengthwise and unwrapped to form a flat map. However shapes of large areas do get distorted.

The distortion is minimal around the point of tangency in the tangent case, and close to the standard parallel in the secant case. Some cartographers, including J. It is often used for mapping Polar Regions with the source located at the opposite pole. Other claims included "absolute angle conformality", "no extreme distortions of form", and "totally distance-factual".

In gnomonic maps great circles are displayed as straight lines. Throughout the globe this scale is constant. It helps to have a reference map for a better orientation. AuthaGraph divides the globe into 96 triangles, transfers them to a tetrahedron and unfolds into a rectangle.

Gall–Peters projection

Map scale factor A globe is the only way to represent the earth with constant scale throughout the entire map in all directions.

This is not the case for most projections, which are defined only in terms of mathematical formulae that have no direct geometric interpretation. The cartographic profession is, by its retention of old precepts based on the Eurocentric global concept, incapable of developing this egalitarian world map which alone can demonstrate the parity of all peoples of the earth.

Here are four other map styles that each come with their own political implications. Proponents of the Peters projection map claim that their map is a good, fair, and non-racist view of the world.

They're comparing their map to the almost-defunct Mercator map. Unfortunately, geographers and cartographers agree that neither map projection is appropriate for use as a map of our planet. The Mercator projection used here is one way of looking at the spherical earth as a flat map.

Used since the 16th century for navigation, straight lines on this map can be used accurately as compass bearings but the size and shape of continents are distorted.

Boston public schools recently announced that they will shift to using world maps based on the Peters projection, reportedly the first time a US public school district has done so. The Population Map Laminated and tubed - - $ The Population map a new map, published January 1,shows where the human beings of the world live, and how many are where.
