[I hope to re-write this when I have a bit more time. Tracking thoughts, for now.]
I’ve been seeing quite a few versions of this map of Africa pop up across all the various flavors of social media in the past week.
Years ago I worked at National Geographic, so I know the difference between a cylindrical map projection, such as the Mercator, which looks like what is used to make this image.
Maps are always political and power related, I won’t argue that, I believe it is the history of the world, the history of mapmakers, and there are a lot of books to read about this.
Mercator’s map was created for sailing, its best use is nautical. But, flatting an oval onto a cylinder results in significant distortion, particularly on the edges. In the late 1600s this distortion was not really important.
Maps distort in area, direction, and distance. Pause for a moment to consider. This Winkel Tripel, which is the projection Geo switched to as standard when I was there (from the Robinson), tries to minimize all three of these (hence the Tripel). It was a good goal, for a map designed 350 or so years after the Mercator, and in a world that had changed.
Once, only adventurers needed maps, the crown, the insane, perhaps, who sailed off the edges. Now we have maps on all of our devices, and not only are they the Mercator projection, they are fixed (fire up the iphone and try to travel west from hawai’i to china). I sometimes express sadness at the limitations of what is on today’s maps, so standardized.
If you’ve gotten through all that noise I just wrote, here is what I am thinking about: why do I need a map that is true to area? or even distance? In this modern world, I don’t use these things. I do need to know direction, and direction, distorted on a mercator, its OK. Area surely has political concerns, from the days of the colonists to whose property is where and where crazy old mr brown’s yard starts. (But you know that, he has a fence.)
What do we, individuals, use maps for now, other than directions in the small sense, local directions? I use them for dreaming. I use them to figure out how to walk from here to there. Sometimes I use them to figure out how long it will take me to get from here to there.
So what is the purpose of that map I linked to above? I think it is to make you feel bad. I’m not sure why, or to what end, but that is the sense I get. Now that you know the area of Africa is Very Large, what now? I also think its interesting that Canada is not included. Maybe because it would have taken up about third?
