The Difference Between Mercator and Peter's Projection maps

Mercator map
  • Was created by the Flemish cartographer Gerardus Mercator in the 16th century
  • it became the standard map for navigation because it showed everything because it allows the ship to sail at a constant compass direction.
  • the lines of longitude and latitude are constant at any point on the map
    • one flaw of the map is that it wildly misrepresents the size of landmasses by making the landmasses farther from the equator larger.
  • used for most street maps and marine navigation
  • in most cases size is associated with importance
    • this map makes the countries of North America and Europe seem far larger than the third world countries around the equator  thereby making them seem far more important

Peter's Projection Map
  • this is a rectangular map that shows the more accurate sizes of the places in relation to the other places around the globe
    • it achieves this goal by distorting the shapes f some places
    • this map shows is part of a family of maps and the places at 45* north and south have no distortion
  • it is named after James Gall and Arno Peters because Gall presented this idea at a science convention in the 1850s and then Peter brought this idea to a wider audience in the 1970s
  • maps based on or using this projection are widely promoted by UNESCO (The United Nations Educational, Scientific, and Cultural Organization.) and is used in most British schools
  • Although in the US only Massachusets and the Boston School District became the first school district to use these maps in March of 2017
  • this map gained notoriety in the late 1900s and began to raise controversy about the creation of maps. 


All in all, I believe that the Peters projection Map should be used in most schools due to the fact that it represents the size of the landmasses more accurately.
