1 Map Scales and Legends #5 -Describe the different types of map scales used #6 – Define Map Legend

2 Map Scale Relationship of distance on map to distance on Earth 1:24,000 1:100,0001:250,000

3 How Map Scales are Represented Verbal –1 inch = 1mile –May not be precise, but close enough for estimates Graphic –Printed on map, if map enlarged or reduced still gives reliable scale Numerical (Fractional) –Ratio 1:500 –Fraction 1/500 –Can be used with any units

4 Large Scale vs Small Scale Large scale 1:24,000 Small scale 1:100,000 1:24,0001:100,0001:250,000

5 Map Legend Explains what symbols used on map mean

6 Conversions you may need 1 mile = –5280 ft –63360 in –1.6 km 1 kilometer = –1000m –.62 miles

7 Practice - AES Calculate the verbal scale –1:62500 –____________mi/in Write the fractional scale of the map provided (bottom center) Write the verbal scale of the map provided –__________mi/in Compare the verbal scale you wrote above against the graphic scale. Are they the same?

8 Assignment: AES – worksheet and read p 60-62, 876 –EC p. 62 GES – worksheet and read pages , 806 –EC p. 170
