What is a map? A graphic representation of the earth’s surface drawn to scale, as seen from above
Uses colors, symbols, and labels to represent features found on the ground
Key=a legend used to explain the meaning of each of the symbols used. For example, a star in a country represents the capital

7. Types of Map Projections
Three basic categories: conic, cylindrical, conic
Maps show 4 things: direction, distance, shape, and size
Only a globe can show all 4 with accuracy at same time

8. Goode’s Interrupted Projection (Equal Area)
Advantage:
+ True Size & Shape of Landmasses
Disadvantage:
-Distances Distorted

9. Robinson’s Projection
Advantages:
+Only minor distortions in size, distance, and shape of landmasses
Disadvantages:
-Polar Areas appear Flat

10. Mercator Projection Advantages:
+Shows true directions & shapes of landmasses
Disadvantages:
-Distances not true
-Size of landmasses near N and S Poles exaggerated

11. Winkel Tripel Most often used Advantages
+Balance between size and shape of land areas, including polar areas
Disadvantages
E & W edges more distorted
