Explanation: The major difference in the map projections based on the area they distort as all he map projection are
projected to some sort of the earth surface areas as they tend to depict the landmass in different areas as related to the shape, size and the direction of the projection of the landmass
.
What are different map projections used for?
Different projections have different uses. Some projections are
used for navigation
, while other projections show better representations of the true relative sizes of continents.
What are the types of map projection?
| 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 is the difference between Mercator and Peters projection?
In addition, Mercator only distorts longitudinal distances (except very close to the poles), whereas
Peters screws up the scale almost everywhere for both longitude and latitude
. This is why Mercator beats out Peters in the world of cartography, and why Google Maps uses a modified Mercator projection.
What are the 4 main types of map projections?
| Rank Map Projection Name Examples | 1 Cylindrical Mercator, Cassini, Equirectangular | 2 Pseudocylindrical Mollweide, Sinusoidal, Robinson | 3 Conic Lambert conformal conic, Albers conic | 4 Pseudoconical Bonne, Bottomley, Werner, American polyconic |

What are the 3 main map projections?
This group of map projections can be classified into three types:
Gnomonic projection, Stereographic projection and Orthographic projection
.
What is the most accurate flat map projection to use?
The lower the score, the smaller the errors and the better the map. A globe of the Earth would have an error score of 0.0. We found that the best previously known flat map projection for the globe is
the Winkel tripel
used by the National Geographic Society, with an error score of 4.563.
What do all map projections have in common?
Terms in this set (13)
They all
have distortion in the size or shape of the continents or countries
. It means that the sizes of the continents are shown in correct relationship to each other.
What are the 5 map projections?
- Mercator. This projection was developed by Gerardus Mercator back in 1569 for navigational purposes. …
- Robinson. This map is known as a ‘compromise’, it shows neither the shape or land mass of countries correct. …
- Dymaxion Map. …
- Gall-Peters. …
- Sinu-Mollweide. …
- Goode’s Homolosine. …
- AuthaGraph. …
- Hobo-Dyer.
What is true map projection?
Conformal, or orthomorphic, map projections
preserve angles locally
, implying that they map infinitesimal circles of constant size anywhere on the Earth to infinitesimal circles of varying sizes on the map. In contrast, mappings that are not conformal distort most such small circles into ellipses of distortion.
Which projection has only one view?
Explanation: Orthographic projection is the representation of two or more views on the mutual perpendicular projection planes. But for
oblique projection
, the object is viewed in only one view.
How do you identify map projections?
To find information about the projection used to create a map,
look at its legend
. The legend of a map may list a projection by name and give its parameters, such as Lambert conformal conic with standard parallels at 34° 02′ N and 35° 28′ N and origin at 118° W, 33° 30′ N.
What are three types of maps?
Notwithstanding the actual medium of the map (e.g., our fleeting thoughts, paper, or digital display), maps represent and describe various aspects of the world. For purposes of clarity, the three types of maps are
the reference map, the thematic map, and the dynamic map
.
What is better than the Mercator projection?
The Gall-Peters projection
(shown below) makes seeing the relative size of places much easier. … Despite these benefits, the Gall-Peters projection has its flaws. It doesn’t enlarge areas as much as the Mercator projection, but certain places appear stretched, horizontally near the poles and vertically near the Equator.
What is wrong with the Mercator projection?
Mercator maps distort the shape and relative size of continents, particularly near the poles. … The popular Mercator projection distorts
the relative size of landmasses
, exaggerating the size of land near the poles as compared to areas near the equator.
What four distortions are there in the Robinson projection?
There are four main types of distortion that come from map projections:
distance, direction, shape and area
.
