  1. Topographic Maps

  2. Topographic Map: • A contour map -

  3. Complicated Topographic Map

  4. Simple Topographic Map I am standing where the land meets the water, what is this called?

  5. *All elevations are relative to sea level 0 meter contour line 0 meter contour line

  6. Profile View of Island Sea level Rises another 5 meters Sea Level rises 5 meters during the night Black paint Sea Level 0 meters

  7. Profile View of Island Sea Level Rises another 5 meters A total of 15 meters 0 meters

  8. 15 meters 10 meters 5 meters 0 meters

  9. How would the island look from the Helicopter with the black lines? What are the values for the lines? 15 m 10 m 5 m 0 m Top View of the Island

  10. Contour Line Features

  11. Which side of the island is steeper? N S

  12. What do you notice about the contour lines? 15 m North South 10 m 5 m 0 m

  13. Gradient: Steep-- Gentle-- Steep Gentle

  14. What is the elevation difference between the two locations? Contour interval– 5 B 15 m A 10 m 5 m 0 m

  15. What is the value of each location? Location A B C D E Elevation _ _ _ _ _ B E 15 m C 10 m D A 5 m 0 m

  16. Reading Topographic Maps

  17. How to use a map scale 15 m 10 m 5 m 0 m 1 KM

  18. Map Scales Ex: 1:24,000 One unit on the map equals 24,000 units on Earth’s surface What about 1:100,000?

  19. Reading Topographic Maps • Contour lines are not all labeled

  20. Index contour- Intermediate contour – What is the contour interval on this map?

  21. Concentric circular contour lines represent a hill or mountain

  22. Depression --

  23. Benchmark • __

  24. River or Streams What direction do rivers flow? *-* What do you notice about the shape of the contour lines on this map?

  25. “V” pattern contours show a river or stream valley. • “V” - Rivers flow downhill

  26. Which direction is the river flowing? N W E S http://www.polleverywhere.com/multiple_choice_polls/MTIzNDQ1MTM0MQ/web
