Learning to Draw Contours

This activity lets you step through a series of maps containing data values for you to analyze by drawing isopleths that connect points of equal value. Across the top of the drawing region are a series of buttons as follows:

  • Erase Last Line - This button erases the last line you've drawn. Hitting this button twice will erase the last two lines you drew.
  • Colors - Use this to select the color of the isolines you draw.
  • Next Map - This button erases the screen and presents more data values.
  • Show Solution - If you want to see how we analyzed the data click on this button.

    • Below the drawing region will be some words to prompt you and make suggestions.
