## What is the Robinson projection best used for?

The Robinson projection is primarily appropriate for general world maps.

National Geographic used it for their world maps for about a decade until 1998..

## What spatial characteristics does the Robinson projection preserve?

A Pseudocylindrical projection that preserves neither scale nor area, but which presents an aesthetically pleasing view of the entire world. The Robinson projection is unlike most other projections in that it is not constructed by a mathematical formula used to transform coordinates systems.

## What are the advantages and disadvantages of the Robinson projection?

Advantage: The Robinson map projection shows most distances, sizes and shapes accurately. Disadvantage: The Robinson map does have some distortion around the poles and edges.

## What are the 4 map projections?

This group of map projections can be classified into three types: Gnomonic projection, Stereographic projection and Orthographic projection.Gnomonic projection. The Gnomonic projection has its origin of light at the center of the globe. … Stereographic projection. … Orthographic projection.

## What are the weaknesses of the Robinson projection?

List of the Disadvantages of the Robinson ProjectionDistortions exist on the edges of the map. … It offers limited benefits for navigation. … The Robinson projection is not equidistant. … It does not provide azimuthal support. … The projection suffers from compression in severe ways.More items…•

## What does the Mercator projection preserve?

Mercator found that to keep the rhumb lines straight he had to make lines of latitude move away from each other as they moved north and south of the equator. In order to do this, he created a projection that preserved the 90° angles between the latitude and longitude lines.

## What is the most accurate map projection?

AuthaGraphAuthaGraph. This is hands-down the most accurate map projection in existence. In fact, AuthaGraph World Map is so proportionally perfect, it magically folds it into a three-dimensional globe. Japanese architect Hajime Narukawa invented this projection in 1999 by equally dividing a spherical surface into 96 triangles.

## What are the disadvantages of the Mercator projection?

Disadvantages: Mercator projection distorts the size of objects as the latitude increases from the Equator to the poles, where the scale becomes infinite. So, for example, Greenland and Antarctica appear much larger relative to land masses near the equator than they actually are.

## Does Mercator projection preserve direction?

Mercator is a conformal map projection. Directions, angles, and shapes are maintained at infinitesimal scale. Any straight line drawn on this projection represents an actual compass bearing. These true direction lines are rhumb lines and generally do not describe the shortest distance between points.

## What is the difference between Mercator and Robinson projection?

Unlike the Mercator projection, the Robinson projection has both the lines of altitude and longitude evenly spaced across the map. … In opting for a more pleasing appearance, the Robinson projection ‘traded’ off distortions – this projection is neither conformal, equal-area, equidistant nor true direction.

## Which projection does National Geographic use now?

Mollweide projectionCartographers at National Geographic chose to use a version of the Mollweide projection for their map highlighting ocean floors, published as the map supplement in the September 2012 issue of National Geographic magazine. This Mollweide projection is referred to as a pseudocylindrical projection.

## Why is Mercator projection bad?

Mercator maps distort the shape and relative size of continents, particularly near the poles. This is why Greenland appears to be similar in size to all of South America on Mercator maps, when in fact South America is more than eight times larger than Greenland.

## What is the difference between Mercator and Gnomonic projections?

Mercator projections are often referred to as cylindrical maps. They represent Earth with parallel lines of latitude and longitude. … The gnomonic projection projects points from a globe onto a piece of paper that touches the globe at a single point. It creates circle routes often used in air travel.

## What are the disadvantages of cylindrical projection?

The downsides of cylindrical map projections are that they are severely distorted at the poles. While the areas near the Equator are the most likely to be accurate compared to the actual Earth, the parallels and meridians being straight lines don’t allow for the curvature of the Earth to be taken into consideration.

## Why do many geographers prefer the Robinson projection?

Geographers prefer the Robinson Projection because it shows the size and shape of most of the land quite accurately. The sizes of the oceans and and distances were also very accurate.
