I don't know about you but I was amazed when I saw this map. I never realised Africa was so big. But then again, geography never was my strength at school.

I thought so as well Q, hence the thread. - Eddy, Jun 26, 2011
I thought you *might* like to have this image right in your post, Eddy. So, I took the liberty of inserting it. If you don't like it, edit it back out. - webdunce, Jun 27, 2011
I did have that originally before I posted. The writing was too small. I have rolled back the thread. - Eddy, Jun 27, 2011

The problem with the Mercator projection is that originally was useful for navigation, because it preserved the angles at the expense of large deformations in shape and size. All 2D projections have to sacrifice something: correct angle means unrealistic area; realistic shape also comes with unrealistic area, and realistic area comes with slight shape distortion, and bad angles. There are more than 100 types of projections. The Robinson and Wikel III projections are two commonly used projections with an overall good compromise.

Mercator projection (progressively distorted; infinite distortion at the poles) alt text alt text

Robinson projection (only significantly distorted at the poles) alt text

Winkel tripel projection (significant distortion only at the poles) alt text

Mollweide projection (shape distortion, but correct areas!) alt text

TsNIIGAiK projection (least distortion characterization, but not popular) alt text

Your wrong impression of the sizes of continents is mostly due to the over-use of the Mercator Projection, so often used in schools.

Land masses are exaggerated more, the farther from the equator they lie. Africa is as close to the equator as you can get. Greenland looks bigger than Africa.

Mercator Projection? You mean we can't blame white guys' egos? - Sabor, Jun 27, 2011

?South Sudan will declare its independence on July 9th, 2011 and it is expected to become the newest sovereign state in Africa and in the world.

alt text

?Someone has called for the creation of "the United States of Africa". If this idea is completed, Africa will pass the Russian federation to become the biggest sovereign state in the world by area.

The African Union is playing an important role in the unity and integration of Africa.

alt text

?The European Union alt text also has territory located in Africa (there are 5 European countries whose integral parts are located in both Africa and Europe).

Interesting information Fidalgo. :) - Nicole-B, Jun 27, 2011
Fidalgo amigo - the creation of north and south Sudan would indicate that a union of african countries will never happen. - ian-hill, Jun 27, 2011
Too many egos - languages - customs - geographies - histories etc etc. - ian-hill, Jun 27, 2011
Thank you so much, Nicole :) - Fidalgo, Jun 27, 2011
I agree with you, Sir Ian, it is too hard for people in Africa to create a sole homeland :) (perhaps the same as the thing called "United States of Europe") :) - Fidalgo, Jun 27, 2011

But then again, geography never was my strength at school.

I have always loved geography. I am horrible at following a road map, but love seeing where different countries and places are in the world and how their location and proximity to other countries plays a part in their culture. I am constantly checking world/country maps.

Imagine my surprise when I first opened your link to see that France, Spain, Germany and Italy were a part of Africa. wink It took me a minute, but I now understand the illustration and it is amazing. Thanks Eddy.

Nor mine wink. I remember a teacher pointing to a map and saying "what country is this?" and I had no idea... the answer was Africa LOL.

To be fair, I thought she was pointing to a specific country *in* Africa wink.

So your teacher should have asked, "What continent is this?" :) - pesta, Jun 27, 2011

The Southern Hemisphere (countries) of the Earth is larger than the Northern Hemisphere. The drawing of the maps were skewed to a larger size for the Northern Hemisphere due to the arrogance of the superior view of the white male population of the time.

If you look at maps of over a century ago you will note that the British Isles were drawn much larger than it really is: the pre-eminent country of the era.

Map drawing was a sop to the ego in charge at the time: white, (upper) middle class male.

Wow! That's truly fascinating. I never knew that, either.

Here are some facts about Africa.

  • The population of the entire continent is 800 million.
  • There are 53 countries in the continent.
  • The largest country in Africa is Sudan.
