Task 2: Map projection


1.- Purpose

2.- Distortion types

3.- Distortion- Areas that are most distorted?

4.- There is more than one version?

5.- Problems

6.- Socio-Cultural implications of using it as a learning resource


1.- It became the standard map projection for nautical purposes because of its ability to represent lines of constant course is straight segments that conserve the angles with the meridians.

2.- The distorsion type that it has is the area one because distorts the size of objects as the latitude increases from the Equator to the poles, where the scale becomes infinite.

3.- It greatly exaggerates areas in highest latitudes. For example: Greenland appears larger that Africa, Alaska appears larger than Brazil and the Antarctica appears as the biggest continent.

4.-Yes, the transverse Mercator projection.

5.-  Most of the main criticism of the Mercator projection are that it gives people a false impression of the size of the world’s landmasses. Other critics say that this projection and the large size of continents like Europe gave an adventage to the colonial powers because it made them appear larger than they really are. Other problem would be that it has often been used in world maps where other projections would have been more appropriate, this problem has long been recognize even outside.

6.-  As this projection makes the areas bigger than they actually are, it provides the imperialistic activities and it creates an ethnic prejudice against the third world since it places Europe in the middle of the map and it makes smaller Africa.



  1. 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.
  2. The Robinson projection has the four different distortions: shape, direction, distance and area.
  3. The greatest distortion occurs near the north and south poles. The range of acceptable distortion in these maps is usually 45 degrees north to south.
  4. No.
  5. This kind of projection isn’t equivalent so it avoids these properties. Distortion close to the poles is severe, but quickly declines to moderate levels moving away from them. The straight parallels imply severe angular distortion at the high latitudes toward the outer edges of the map, a fault inherent in any pseudocylindrical projection.
  6. This type of projection usually uses because makes the world “look right”. Better balance of size and shape of high-latitude lands than other projections.robinson


  1. It is the best one for projecting small scale maps.
  1. It has radial symmetry in the scales and hence in the distortions: map distances from the central point are computed by a function r(d) of the true distance d, independent of the angle; correspondingly, circles with the central point as center are mapped into circles which have as center the central point on the map.
  1. It depends on where the center is fixed. As you go to the edges it is more distorted.
  2. Yes.
  3. You cannot see the whole world at once; it is only useful for one hemisphere.
  4.  These maps are useful for navigation.





We’ve chosen two countries, Italy, in Europe, and Egypt, in Africa, in order to explain an evidence of distortions in the maps within different projections.

In the Robinson projection: In this projection it is clear that Egypt is bigger than Italy so both countries are right represented on it. Although this, Egypt is in the northern hemisphere.

In Mercator projection: Italy occupied a bigger place than it might and Egypt is closer to the Equator line in this projection. There was given importance to Italy and Egypt because this projection was made for sailing giving more importance to colonized countries.

In Azimuthal projection: this projection centre is placed on the equator, and its focus in Africa, in this way Italy and Egypt are in their right positions, with their almost accurate proportions.


In our case, two of us agreed that Mercator Projections was the best one in order to use it in a classroom meanwhile four of us though that the Robinson’s one is the best option to use in the school if we only focus on countries then they can be seen clearer and easier than in the other two. Besides, this projection only has got a distortion in poles and his shape wha it has not got too much important in primary learning.


Our treasure hunt consists on some riddles about the human body and each riddle links with a picture of each part.

To make this treasure hunt more interactive each time children guess a riddle the teacher will give them a paper with a word that is written in Morse. After guessing all the riddles, children will have to have ten papers that they have to translate from Morse to English in order to get a complete sentence that is the final part of the treasure hunt.

In that way, our goal is children learn different things (in this case, human body) in an active way, having fun and if the teachers want they can also work in groups.


Nowadays media and in particular social networks determine our social life. It is a way in which people can obtain acceptance of other people who don’t really know and making us forget what is our own identity.

Here we’ve got two examples of how social networks can make us believe something which does not exist.

Amalia Ulman pretended to have a ‘perfect life’ in order to prove how important are social networks nowadays. Her work was made out of three parts, the first one she pretended to be a ‘sugar baby’, young people who have relationships with wealthy people to get some profits.

The second part, she pretended to be a rude and sexy girl, with a style similar to Kim Kardashian. In this part she became a drug-addicted and finally in the third part she pretended to start a rehab and live a healthy life. All her photos were published on a Gallery of Art due to the impact of her work.

The next example is quite similar, but instead of lying thousand people, a girl called Zilla Van, lied her family and friends telling them she was going on a trip to Asia. She worked as graphic designer and with Photoshop she retouched some photos made in her own home.


Now, we’re going to explain a common distortion. If someone tell us to draw a heart, we use to draw this <3, but we know that this is not the real shape of the heart. And even when know it, we follow doing it in the same way. The teachers teach to our children to draw n tis way and in the centre of the body but we know that is more to the left.


Nowadays media is not neutral since behind them there are some people that have different perspectives that have an influence on the information that they transmit so this information is always subjective and therefore, the reality is distorted.

Something similar occurs with map projections since every researcher (Robinson, Mercator, Azimuthal and so on) had their own point of view about the world and the countries so their maps transmitted distorted realities and people thought that it was all correct.
