  1. Aim: What is a topographic profile? Do Now: Determine the direction Green River is flowing. Why?

  2. Topographic Profiles • Topographic maps show the elevation or vertical distance above sea level of the surface of Earth. • Topographic profile is a side view of an area.

  3. From the June 2007 NYS Regents Construct a topographic profile from D to E

  4. Step 1 • Understand the contour interval. Contour Interval = 10m (in the legend)

  5. Step 2 • Get a sheet of paper and line it parallel to the line D-E line and mark them.

  6. Step 3 • Put a small line next to each contour line it passes (do not mark the river).

  7. Step 4 • Enter each contour interval value next to each line:

  8. Step 5 • On the answer sheet, be sure that the graph is properly labeled with elevation as the dependent and distance as the independent variables.

  9. Step 6 • Place paper with the marked D-E line on the graph. D and E must match along the x-axis.

  10. Step 7 • Mark the graph at the proper elevations (use a straight edge for accuracy).

  11. Step 8 • Connect the lines. The profile must not go under the 10m mark for the Creek.

  12. In what direction is Amethyst River and Copper Creek flowing? N

  13. Summary (based on the diagram) What is the elevation of A, B, C, and M? What is the maximum elevation of the hilltop between letters C and D? What are hachure marks? Why are they useful on a map? List the steps to produce a topographic profile.
