World Map Equal Area Projection
The mercator projection is still commonly used for areas near the equator however where distortion is minimal.
World map equal area projection. It is inspired by the widely used robinson projection but unlike the robinson projection retains the relative size of areas. Robinson intended the map which is neither equal area nor conformal as a general purpose tool. The lambert cylindrical equal area projection with tissot s indicatrix of deformation cylindrical equal area projection with oblique orientation in cartography the cylindrical equal area projection is a family of cylindrical equal area map projections. The gall peters projection is not the only equal area projection.
This gives a lovely spherical feeling to this two dimensional map. Cylindrical equal area projection of the world. Tobler world in a square. He published a paper on it in 1885.
The projection is neither equal area nor conformal its main feature is that all of the parallels are curved except for the straight poles and equator. It is occasionally used by nasa other scientists for presenting statistical information where the true sizes of materials being presented are intended to be shown to scale. The equal earth map projection is an equal area pseudocylindrical projection for world maps invented by bojan šavrič bernhard jenny and tom patterson in 2018. The projection is a particular example of the cylindrical equal area projection with latitudes 45 north and south as the regions on the map that have no distortion.
Image daniel r strebe our mesmerising world geology map utilises the winkel tripel projection. Because the sphere is not a developable surface it is impossible to construct a map projection that is both equal area and conformal. The sinusoidal projection for instance provides an equal area projection. As a result of these criticisms modern atlases no longer use the mercator projection for world maps or for areas distant from the equator preferring other cylindrical projections or forms of equal area projection.
Standard parallel at 40 n. The sinusoidal projection is a mathematically precise equal area world map. Gall is credited with describing the projection in 1855 at a science convention.
