1. Map Projections

2. Students must be able to identify and understand the following projections.
Mercator
Polar
Robinson

3. Mercator Projection Most Accurate in the tropics
from Cancer to Capricorn
Most Distortion at the North and South Poles

4. Mercator Projection Used for: Locating Latitude and Longitude
Sea Captains use it for navigation at sea

5. Mercator Projection Characteristics: All lines are at 90 degree angles
Simplest to read
Accurate direction
Distorted size, distance, shape

7. Robinson Projection Most Accurate at the equator
Most Distortion around the outer edges

8. Robinson Projection Same characteristics as the Mercator except:
lines of longitude are curved
shapes at the poles are flat and not as distorted
used mostly in classrooms--one of the most accurate maps

10. Peters Projection Most Accurate at showing the actual size of places
Most Distortion in direction

11. Robinson Projection Same characteristics as the Mercator except:
shapes are distorted
Direction is innacurate
