Learning to Draw Contours
In the space below, you can step through a series of maps containing
data values that you'll be asked to "analyze" by drawing isopleths
that connect points of equal value. Each lesson presents more data points
within the same field.
Across the top of the drawing region are a series of buttons:
-
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.
