Lesson 2: What Christopher Columbus and Ptolemy already knew.




Cylindrical Projection

Cylindrical projection

Figure 2.1.3, (“Miller Cylindrical,” USGS, 2006. http://erg.usgs.gov/isb/pubs/MapProjections/projections.html)

Figure 2.1.3.1, (USGS, 2006. http://erg.usgs.gov/isb/pubs/MapProjections/projections.html)

Description: Cylindrical projections are designed as if a cylinder were wrapped around the world; both the longitude and latitude lines are straight and parallel. The example above might fit nicely around an empty paper towel roll. Notice that if a cylindrical projection were wrapped around a globe it would not touch the poles at either end unless it was crumpled up.

Advantages:

  1. can be created on a flat piece of paper, making it convenient and inexpensive
  2. accurate for depicting small areas
  3. can depict the entire earth at once

Disadvantages:

  1. distorts large areas
  2. The areas near the poles appear larger than they really are. For example, South America is eight times larger than Greenland in reality, but on Figure 2.1.3 Greenland appears to be larger.
