What do Robinson projection maps show?
The Robinson projection is a map projection of a world map which shows the entire world at once. It was specifically created in an attempt to find a good compromise to the problem of readily showing the whole globe as a flat image.
Where is the Robinson projection used?
general world maps
The Robinson projection is primarily appropriate for general world maps. National Geographic used it for their world maps for about a decade until 1998.
Where is the Robinson map distorted?
The Robinson projection is not conformal; shapes are distorted more than they would be in a truly conformal projection. However, shapes are not distorted very badly within about 45° north or south of the equator or within about 45° of the map’s central meridian.
Which property does the Robinson map projection preserve?
A Pseudocylindrical projection that preserves neither scale nor area, but which presents an aesthetically pleasing view of the entire world.
Which regions are most distorted on a Robinson Projection?
Although the Robinson Projection is not free from distortions, and the most severe distortions are near the poles. However, distortions near the outer parallels at high latitudes are common on most pseudo-cylindrical map projections. The distortions become less objectionable moving away from the poles.
What type of projection is the Robinson Projection?
Introduction
| Projection | Type | Key virtues |
|---|---|---|
| Lambert Conformal Conic | conic | conformal |
| Mercator | cylindrical | conformal and true direction |
| Robinson | pseudo-cylindrical | all attributes are distorted to create a ‘more pleasant’ appearance |
| Transverse Mercator | cylindrical | conformal |
What type of projection is the Robinson projection?
Where is most distortion found on a Robinson projection?
poles
Although the Robinson Projection is not free from distortions, and the most severe distortions are near the poles. However, distortions near the outer parallels at high latitudes are common on most pseudo-cylindrical map projections. The distortions become less objectionable moving away from the poles.
Where is most distortion found on a Robinson Projection?
What is 4 distortions of the Robinson Projection?
There are four main types of distortion that come from map projections: distance, direction, shape and area.
Why was the Robinson projection used for world maps?
It was developed because modern map makers had become dissatisfied with the distortions inherent in the Mercator projection and they wanted a world projection which ‘looked’ more like reality. In its time, the Robinson projection replaced the Mercator projection as the preferred projection for world maps.
Where does the tearing occur in a Robinson Map?
Tearing occurs along the edges of a Robinson map. Compression: Robinson projections are not equivalent; they do suffer from compression. However, the amount of area distortion is generally low within about 45° of the equator. Equivalence: Robinson projections are not equivalent; they do suffer from compression.
What do the lines on a Robinson map look like?
Robinson maps show lines of latitude as parallel straight lines and lines of longitude as nonparallel lines that become increasingly curved as you move farther away from the map’s central meridian.
What are the edges of the Robinson projection?
These east and west edges are markedly less curved than are the edges of other pseudocylindrical projections (the result being that the Robinson projection generally suffers from less shearing than do other pseudocylindrical projections). Tearing occurs along the edges of a Robinson map.
