Random pictures about Africa

 

Africa is HUGE. Merkator projection makes land masses near the equator appear relatively smaller and ones closer to the poles to be larger.  Hat-tip to Lucas Machias.

Population density

Key to color scale. Multiply by 3 to get people per square mile. Ohio and California have a density of 100/km^2, Washington State and New Hampshire have about 50/km^2 and Kansas and Utah have about 15/km^2.

Rail lines. Only South Africa has a network of rail for inter-region transportation. The others are totally export oriented.

It is a pity the SA system could not be extended past Lake Victoria, through Ethiopia to the Red Sea, and then continue north the the Mediterranean. And another line from the ports of Dakar or Monrovia eastward, skipping over the northern parts of Cote de Ivoire, Ghana, Nigeria to just south of Lake Chad.
