Let’s break this task down step by step.

To begin, let’s mark the index contours of different elevation levels using different colors.

  • The lowest contour in this section will be light blue.

  • The next higher contour will be blue.

  • The highest one here will be red.


Now, let’s start determining the relative elevation of each control, beginning with the lowest — in this case it is probably the easiest way to go.

  • The lowest control is Control 7 — it is the only one located below the light blue contour.

  • Then we have Control 4, Control 3, and Control 8, which are positioned between the light blue and blue contours.
    Among them:
    — Control 3 is closest to the light blue contour,
    — Control 4 is a bit higher,
    — and Control 8 is the highest of the three, almost touching the blue contour.

  • Next, Control 2/6/10 is located in a depression and are the lowest from the red contour.

  • Then comes Control 11, which lies two contour lines below the red one.

  • After that, Control 9 sits about one and a half contour lines below the red contour.

  • And finally, the highest control in this section is Control 5 — it is located just half a contour line below the red contour, which is the highest index contour in this area.

Order from lowest to highest:
Control 7, 3, 4, 8, 2/6/10, 11, 9, 5.
