From 2-D to 3-D 1. If you wanted to turn a sphere (3D) into a rectangle (2D), what challenges would you come across? Click on the link below to answer questions 2- on your note worksheet. http://www.classzone.com/books/earth_science/terc/content/investigations/es0301/es0301page01.cfm

Planar Projection What area of this map is the most accurate? What area is the least accurate?

Cylindrical Projection What area of this map is the most accurate? What parts of this projection are distorted?

Conic Projection When might you use this map projection?

Winkel Tripel Projection Most common projection Balances size and shape well Polar areas are only slightly distorted

Robinson Projection Sizes and shapes of east and west regions are accurate Polar areas are flattened

Goode’s Interrupted Equal-Area Shows sizes and shapes correctly Distorts distance

Mercator Projection Accurate at the Equator, but distorts size and distance Shows true direction and landmass shape Good for sea navigation

What do you think is the best map projection for each of the following tasks? Explain your answer. Sailing a ship from the southern tip of South America to Australia. Driving from San Francisco, CA to Washington, DC. Flying from the North Pole to the South Pole.
