It is also modeled more accurately as an Maps do not suffer from the above shortcomings and are more practical than globes in most applications.
A map is a replica or representation of certain things that exist in real life.
Distortion increases by moving away from standard parallels. Originally, this and other map projections were achieved by a systematic method of drawing the Earth’s meridians and latitudes on the flat surface. While the Peters projection map is superior in its portrayal of proportions and sizes, its importance goes far beyond questions of cartographic accuracy – … Big News! Examples include It is a model of reality. The shape of the Earth is represented as a sphere. Robinson called this the orthophanic projection (which means “right appearing”), but this name never caught on. Between the secant lines where the surface is inside the globe, features appear smaller than in reality and scale factor is less than 1. It is impossible to flatten any spherical surface (e.g. Scale factor of 2 indicates that the actual map scale is twice the nominal scale; if the nominal scale is 1:4million, then the map scale at the point would be (1:4million x 2) = 1:2million. The Peters map, the work of the German historian Arno Peters, provides a helpful corrective to the distortions of traditional maps. Examples of equidistant projections are Directions from a central point to all other points are maintained accurately in True-direction projections are used in applications where maintaining directional relationships are important, such as aeronautical and sea navigation charts.

Stereographic projection is a In orthographic projections, the point of perspective is at infinite distance on the opposite direction from the point of tangency. 1) Mercator Projection… The best known map projection is named for its inventor, Gerardus Mercator, who developed it in 1569. Looking for GIS data? The Robinson projection is highly unique. All projections cause distortions in varying degrees; there is no one perfect projection preserving all of the above properties, rather each projection is a compromise best suited for a particular purpose.Different projections are developed for different purposes. The scale of Mercator projection distortions For starters, it’s important to fully get the scale of the problem related to the unconscious use of Mercator projection. No flat map can be both equal-area and conformal. Similarly, when trying to project a spherical surface of the Earth onto a map plane, the curved surface will get deformed, causing distortions in shape (angle), area, direction or distance of features. The graticule layout is affected by the choice of the aspect.The cone may be either tangent to the reference surface along a Scale is true (scale factor = 1) and there is no distortion along standard parallels. In response to such discrepancies, Dr. Arno Peters created a new world map that dramatically improves the accuracy of how we see the Earth. Robinson began with an artistic approach; his first intention was to achieve a plastic and aesthetic balance. Unlike all other projections, Professor Robinson did not develop this projection by developing new geometric formulas to convert latitude and longitude coordinates from the surface of the Model of the Earth to locations on the map.
A common method of classification of map projections is according to distortion characteristics - identifying properties that are preserved or distorted by a projection.
