ProjectionsMercator:

Meridians not converge at the poles and form together with the parallel mesh with a perpendicular straight lines other.

Cylindrical projection Aimlessly lines become straight lines on the Mercator

projection. The Ecuador or two latitudes symmetrical around

Ecuador This form of projection is conformal. Small forms are

represented properly because in this projection the local angular relationships are maintained.

Peters: Conservation of angles Ecuador situated in the center of the map It maintains the actual surface of the countries, but

shapes and distances are changed.

Robinson:

It shows the size of oceans and continents in a very successful way.

To achieve this Robinson turned to distort the North Pole and the South Pole.

Meridians are equally spaced and appear as elliptical arcs, concave from the central meridian.

  The distance between them decreases beyond these points.

  The poles are 0.53 times the length of Ecuador.
