    Question

    On which of the following projection, the world map can be prepared?

    A.

    Zenithal Equal Area Projection

    B.

    Cylindrical Equal Area Projection

    C.

    Bonne’s Projection

    D.

    Gnomonic Projection

    Correct option is B


    Introduction
    A world map requires a map projection that can represent the entire globe. While many projections are used for world maps (like Mercator, Robinson, or Winkel Tripel), the Cylindrical Equal Area Projection is suitable for a world map and is designed to preserve the equivalence of area (equal-area property) across the entire map. This feature is vital for comparing the size of continents and countries worldwide.
    Information Booster
    · Projection Type: It is a type of pseudocylindrical or orthophanic (equal-area) projection.
    · Primary Feature: The map is constructed so that every area on the map is proportional to the same area on the Earth, ensuring correct area comparison.
    · Suitable for: Used frequently in atlases to show distribution patterns and is a simple equal-area projection for world maps.
    · Distortion: Distances are correct along all parallels and the central meridian(s), but shapes are increasingly distorted away from the central meridian(s) and near the poles.
    · Mathematical Basis: Mathematically based on a cylinder tangent to the Equator.
    Additional Points
    · Zenithal Equal Area Projection: Also known as Azimuthal Equal Area Projection, it is best for showing polar regions or hemisphere maps, as distortion increases away from the central point.
    · Bonne’s Projection: A pseudoconical equal-area projection often used for single continents or countries, not typically the standard for a complete world map.
    · Gnomonic Projection: An Azimuthal projection where great circles are straight lines; best for navigation between two points, not for general world maps as it can only show slightly more than a hemisphere.
