The Mercator projection


The Mercator projection

The Peters projection

  • Arno Peters in 1973

  • It has:

    • Fidelity of position and area

    • Fidelity of axis

    • Different indicators with different colors

    • Neutrality

  • What about the size? – the”hanging sheet” effect

  • Helps to improve creative thinking and problem solving

  • Size and importance – socialequality


Controversies

  • Mercator projection

    • Based on the worldview of the sixteenth century

    • Alleged eurocentrism

    • Colonial attitude

    • Favors the countries of the global North

    • In the focus of cartographic and geographic debates since its inception (Robinson, Snyder, Vajukovic, Maling, Kaiser)

    • Anti-rectangular resolution form US cartographers

      • Cartographically inappropriate
