teaching geologic map interpretation.
Google Earth is a terrific resource for teaching geologic map interpretation
- Google Earth satellite images in many places in the world show
bedrock with strong, contrasting colors in areas with little vegetation
to obscure contacts and unit relationships.
- Imagery is seamless, and, in many areas of the world, the level of detail is amazing.
- Google Earth is free, and students can access Google Earth from their own computers.
What makes Google Earth truly extraordinary for teaching geologic
map interpretation is its interactive 3D terrain viewing capability.
The 3D view also helps make it clear what is topographically high and what is topographically low. As illumination direction changes, perception of what is up and what is down changes. At left, the illumination direction for the top image is opposite that for the bottom image. To most people, the dark red unit looks lower on the top image and higher on the bottom image (although it may be just the opposite for you!). The 3D view, however, helps students see that the red unit is at lower elevations than the pale pink unit.
