The Mollweide projection is an equal-area map projection. It preserves the size of figures, but
heavily distorts the shapes when getting nearer to the edge of the map
.
What is wrong with the Mollweide projection?
Distortion. Mollweide is an equal-area (equivalent) projection.
Shapes, directions, angles, and distances are generally distorted
.
What are some of the negatives 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.
What is the biggest problem with the Mercator projection?
The biggest downfall of the AuthaGraph map is
that longitude and latitude lines are no longer a tidy grid
. As well, continents on the map are repositioned in a way that will be unfamiliar to a population that is already geographically challenged.
What is the main disadvantage of a Mercator projection quizlet?
One disadvantage of using the Mercator projection is
that it distorts size of areas
, particularly as you get closer to the North and South Poles.
What are the pros and cons of a 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. Who uses it? The Robinson is most commonly used by students, teachers, textbooks and atlases.
What are the 4 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 is one drawback of the Homolosine projection?
The resulting Goode homolosine projection is most common in its interrupted form. Disadvantages:
Mercator projection distorts the size of objects as the latitude increases from the Equator to the poles, where the scale becomes infinite
.
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
.
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.
What is the most accurate map projection?
AuthaGraph
. 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 is a problem with the Peters projection?
Countries are stretched horizontally near the poles and vertically near the Equator, so although the size may be right, the shape definitely isn’t. The problem is,
it’s impossible to stretch the 3D sphere shape of the Earth onto a 2D sheet of paper
.
Where is the most distortion found on a Robinson map?
Robinson (1963)
Directions true along all parallels and along central meridian. Distances constant along the equator and other parallels, but scales vary. All points have some distortion but it is very low along the equator and within 45° of centre. Distortion greatest
near the poles
.
What is the drawback to the Goode Homolosine projection map?
Limitations. The
Goode homolosine projection is supported on spheres only
. For an ellipsoid, the semimajor axis is used for the radius. The equal-area property and some other distortion properties are not maintained when an ellipsoid is used.
What do you call someone who makes a map?
The Oxford Dictionary of English app defines
a cartographer
as “a person who draws or produces maps.” Merriam-Webster’s online dictionary says a cartographer is “one that makes maps.” And the Cambridge Dictionary, also available online, states that a cartographer is “someone who makes or draws maps.”
What are the disadvantages of a Isoline map?
| Advantages Disadvantages | You can see gradual changes They are very time consuming to make | They avoid the problem of boundary lines. They can be difficult to read if the lines are very close together, and the numbers and lines are very small. |
