After completing the model, students addressed issues of orientation and scale. Here a student
orients his model of Mt. Woodson to an aerial photograph of the same region. The students
calculated the scale of their model, approximately 1:14,000.
Using the program VistaPro, we had the students view 3-D movies of features such as Mount
Shasta (above left) and craters on Mars (above right.) They then created topographic maps of
the features.
To the left is a DEM (digital elevation model) of a portion of Mount Shasta.
To the right is a student's topographic map of the craters on Mars.
