Maps
We are going to discuss between two maps the
Peters
and the
Mercator's
. And we are also going to answer one question:
WHICH MAP PROJECTIONS ARE MOSTLY USED TODAY?
Mercator´s Map
The Mercator projection was developed in 1569 by Gerardus Mercator as a navigation tool. The lines of latitude and longitude are all parallel. If a navigator wishes to sail from Spain to the West Indians, all they have to do is draw a line between the two points and the navigator knows wich compass direction continually sail to reach their destination. The Mercator map has always been a poor projection for a world map yet people found it useful for wall maps, atlas maps, and maps in books and newspapers published by non-geographers. It became the standard map projection in the mental map of most people.
Peters Map
German historian Arno Peters called a conference in 1973 to announce his new map projection that treated each country fairly by representing the area accurately. The Peters projection map uses a coordinate system that showed parallel lines of latitude and longitude. Arno said that his map more fairly displayed third world countries than the popular Mercator projection map, wich distorts and dramatically enlarges Eurpe and North America countries.
Maps
People of the Peters projection may say that their map is a good, fair and non-racist view of the world.
But geographers and cartographers agree that non map projection is good for use as a map of our planet.
All maps distort distance, shape, area, or direction to present a map that meets the people´s needs. This shows that you cannot make a completely accurate map from a spherical Earth.
Introduction
The real life of Gerardus Mercator
The real name of Gerards Mercator was Gerardus Kermer, but he changed it when he was at school and his mother passed away. He left the university early and travelled trough several cities working, in many different jobs. Some of them are: an instrument maker; a teacher; etc. His travels also lead to his interest in geography, and with his mathematical talent and his interest in cartography. It is not surprise that he started working as a map maker, but there was a problem maps in that time were mostly not accurate. So he created a map that would make it easy to travel from one place to another. Today we call this maps Mercator´s projection.
More about maps
A lot of different agencies use the Peters map because it represents the developing countries at their true proportion.The Peters map has been adopted in many different places, but remains a curiosity in the United States.
The mapmaker´s difficulty is that you cannot show both shape and size accurately. The Mercator´s projection creates increasing distortions as you move away from the equator.
Even more about maps
As you get closer to the poles in the Mercator´s map the distortion becomes severe. We refer to the problem size on a Mercator projection as " the Greenland Problem". Because the Mercator projection distorts size so much at the poles it is common to crop Antarctica off the map.
If there are so many other projections to chose from, why is that today the Mercator projection is still such a widely recognized image used to represent the globe? The answer may be simply convention or habit. The inertia of habit is a powerful force.
Characteristics of Peters map:
- The Peters map is an equal area map.
- This map shows all areas - wether countries, continents or oceans - according to their actual size.
- The Peters map shows equal positions.
- Fairness to all people.
- The Peters map is the map of our day.
Comparing
The North is 18.9
million square
miles
The South is 38.6
million square
miles.
My opinion:
I have read a lot of different things during researching for this presentation. Some websites say that Peters projection is better other say the opposite. But I think that the closest map of the Earth is the Peters Map. Even if the Peters map is the closest map of the Earth, the Mercator's map is the mostly map use today. Most of the people prefer using the Mercator's map only because it is the one that they had always used so is easier to use if you want to look for a place. The same happens to me.
Thanks for listening!

Answer for the research question.
Question-Which map projections are mostly used today?
Answer-The map that it is mostly used today is the Mercator's map, but the closest map of the Earth is the Peters map.
