The Gall–Peters projection is a rectangular, equal-area map projection. Like all equal-area projections, it distorts most shapes. It is a cylindrical equal-area projection with latitudes 45° north and south as the regions on the map that have no distortion. One projection isn't enough; it's almost impossible to accurately project the whole world on one map. As geographers, this term will be familiar. This is the world's most well-known and most recognised map projection. The Mercator projection is a cylindrical map created in 1569 but Gerardus Mercator. This projection was widely used in schools, and even Google used it until 2018. Although the Mercator projection has problems, it is still one of the most widely used map projections. On this projection, the most accurate projection is closest to the equator, but as you move away from the equator, more distortion occurs. As you can see on the image below, countries further from the equator are not accurate sizes and appear stretched. Greenland and Africa look to be the same size, but really, Africa is actually 14 times larger than Greenland. 1 On Mercator's map, Antarctica is bigger than all the continents, but in reality, Antarctica is about the same size as the US and Mexico put together.

The word Tripel comes from the German term for merging three things together. For this map, Winkel tried to reduce the distortion of three elements; area, distance, and direction. However, distortion still exists. Parallel lines have some curvature, and longitude lines curve further as they move away from the meridian. In 1998, the National Geographic Society began using this map as the dominant world map. 2

This map projection is flat-based, also named a plane projection. From the viewpoint of the top or bottom of the globe, the projection can display one/part of the hemispheres. It produces a circular map. This isn't the most common of map projections.

Donald, I’m joking, I’m not trying to cancel Gerardus! I’m impressed he did all that with just his brain and a ruler. But we should probably have something accurate . I’m not sure we could say he was a racist – he never travelled, and was more of a devout Catholic scholar. There are 3 different types of map projections. They all project the world in slightly different ways, providing different levels of distortion. AzimuthalThe Peters World Map is an Equal Area cylindrical projection with standard parallels at 45 degrees thus resulting in a distortion of shape which is stretched about the equator and squashed towards the poles, but having the great advantage that all countries are correct in size in relation to each other. Widely used in educational and business circles as an icon of the modern concept of world equality. THE HISTORY

A map projection is a method of showing our earth (or smaller sections of it) on a flat surface. It involves transferring latitudes and longitudes of our spherical earth, which is 3D, onto a flat and 2D surface. Our world isn't flat, but when we look at maps, it's been manipulated in a way that we can view it from a flattened perspective. The AuthaGraph was created in 1999 by Hajime Narukawa, and is useful for reducing distortions while still producing a rectangular map. This design, once folded, can produce a globe. Naruwaka split the globe up into 96 triangles, projecting these triangles onto a tetrahedron (pyramid with a triangle base). Once unfolded, the tetrahedron becomes a rectangle, displaying the projected world. In this map, countries are proportionate; however, shapes are slightly distorted, some countries are in different locations compared to other maps, and longitude and latitude lines are more sporadically laid out.Maps based on the projection are promoted by UNESCO, and they are also widely used by British schools. [3] The U.S. state of Massachusetts and Boston Public Schools began phasing in these maps in March 2017, becoming the first public school district and state in the United States to adopt Gall–Peters maps as their standard. [4] That’s the thing – it’s fundamentally impossible to get a nice, neat, rectangular but accurate map of the world. People have been suggesting using the Peters projection, but where Mercator distorts size but keeps shape, Peters is accurate with size but not shape. The best thing, I think, is a physical globe. The Gall–Peters projection achieved notoriety in the late 20th century as the centerpiece of a controversy about the political implications of map design.
