The meridians of the Robinson projection curves are gently stretching the poles into long lines. The projection is neither equal-area nor conformal because of the compromise to show the whole planet.

The Robinson projection was created to show the globe as a flat image readily. Pseudocylindrical projections include sinusoidal with same horizontal and vertical scales. On a pseudocylindrical map, points further from the equator have higher latitudes than other points, preserving the north-south relationship. The scaling of the pseudocylindrical projections are straight along the central meridian and also along the parallels. Pseudocylindrical projections present the meridian as a straight line while other parallels as sinusoidal curves which are longer than the central meridian. The distortion caused by the Mercator distorts the perception of the entire planet by exaggerating the areas laying far from the equator. Mercator distorts the size of geographical objects because its linear scale increases with the increase in latitude. Mercator projection is an example of cylindrical projection which became a standard map projection because of its ability to represent lines of steady course. The north to south stretching equals east to west but grows with latitude faster than east to west stretching in the case of central cylindrical projection. Cylindrical projections are distinguished from each other by the north to south stretching denoted by φ. The projections stretch from east to west according to their geometric constructions and are the same at any chosen latitude. Types of Map Projections CylindricalĪ cylindrical projection is any projection in which the meridians are mapped to parallel spaced vertical lines and latitudes are mapped to horizontal lines.

There are several map projections which preserve some of the properties of the sphere at the expense of others. The map projection is classified depending on the type of projection surface on which the globe is projected conceptually.

Some of the distortions on the maps are acceptable while other distortions are not acceptable depending on the purpose of the map. Map projections are important in creating maps with map projections distorting the surface in some way. Map projections are a systematic transformation of longitudes and latitudes of a location on the surface of the sphere. What Are the Different Types of Map Projections? A map of the our world.
