Document Summary
Area: equal area/equivalent projections allow representation of areas in constant proportion. Shape: conformal projections accurately record shapes but distort area. Distance: is often distorted on a map. Some projections show true distance in all directions from a central point. Direction is often distorted but some projection show true direction. One the earth"s surface the shortest distance between two points is always along a great. Circle: the center point of the great circle is the center of the earth. Robinson projection - an effort to compromise between equal area and conformal mapping. Peter equal area projection - shows countries true size but distorts shape mercator - represent better than size. The day of "7 billion" was declared by the population division of the united nations on. In 2015 the global population increased by 78. 3 million people. Fastest rat of increase: africa (2. 4 per year = 28. 6 million people ) Largest absolute increase: asia (. 9 per year = 39. 2 million = 4. 34)
