What is the purpose of the Mercator projection?
Description. Mercator is a cylindrical conformal map projection that was designed to provide correct compass bearings for sea voyages. At minuscule scale, all local shapes are exact and correctly characterised, which is another property of this projection. In 1569, Gerardus Mercator presented it.
What makes a Mercator map useful for navigation?
Because any straight line on a Mercator projection map is a line of constant true bearing that allows a navigator to plot a straight-line course, it is commonly used for navigation charts. …
What is the distinction between the Mercator and Robinson projections?
The lines of height and longitude in the Robinson projection are evenly spaced across the map, unlike the Mercator projection. … The Robinson projection ‘traded’ distortions for a more appealing appearance – this projection is neither conformal, equal-area, equidistant, nor true direction.
Which map projection is best for navigation, particularly near the equator?
The Mercator Projection is the most helpful map projection near the equator since it is the most accurate.
What are the four different kinds of map projections?
Name of Rank Map Projection
1 Mercator Cylindrical, Cassini Equirectangular
2 Mollweide, Sinusoidal, Robinson, Pseudocylindrical
3 Albers conic, Lambert conformal conic
4 American polyconic Bonne, Bottomley, Werner, Pseudoconical

Which flat map projection is the most accurate?
The lower the score, the fewer the mistakes and the more accurate the map. The error score of a globe of the Earth would be 0.0. The Winkel tripel used by the National Geographic Society is the best previously known flat map projection for the globe, with an error score of 4.563. Examine the response of
What’s wrong with Robinson’s forecast?
Distortion. Robinson’s projection is neither equal-area nor conformal. Shapes, regions, lengths, directions, and angles are all distorted. … Area distortion increases with latitude but remains constant with longitude.
What is the Mercator projection’s flaw?
The shape and relative size of continents are distorted on Mercator maps, especially towards the poles. … The widely used Mercator projection distorts the relative sizes of landmasses, increasing the extent of land near the poles in comparison to areas around the equator. Read:
What is the name for two points on a map?
A cartographer is someone who creates maps.
The shortest distance between two sites is represented by the great circle route, an imaginary line that follows the arc of the Earth.
Map projection is a mathematical procedure for representing the Earth’s curving surface on a flat map surface.
What are the four distortions in the Robinson projection?
Distance, direction, shape, and area are the four basic types of distortion caused by map projections.
What do you name a person who draws maps?
A cartographer is defined as “a person who draws or produces maps” in the Oxford Dictionary of English app, “one who makes maps” in Merriam-online Webster’s dictionary, and “someone who makes or draws maps” in the Cambridge Dictionary, which is also available online.
What is the purpose of Robinson projection?
Robinson’s projection is one of a kind. Its main goal is to generate globe maps that are visually appealing. It’s a compromise projection; it doesn’t eliminate any distortion, but it keeps all sorts of distortion to a minimum over the majority of the map.
What are the three main projections for maps?
Gnomonic projection, Stereographic projection, and Orthographic projection are the three types of map projections available.
What projection does National Geographic use for their maps?
Usage. For general globe maps, the Winkel Tripel projection is acceptable. Since 1998, the National Geographic Society has adopted a variation with a standard parallel at 50°28′.
Which map projection is the best?
AuthaGraph. This is without a doubt the most accurate map projection available. In fact, the proportions of the AuthaGraph World Map are so perfect that it suddenly folds into a three-dimensional world. This projection was created by Japanese architect Hajime Narukawa in 1999 by evenly splitting a spherical surface into 96 triangles.
