USGS Earthshots: Satellite Images of Environmental Change

By Activity, Article, Education, Imagery, Lesson Plan, Observation, Outreach, Resource, , , , ,

The USGS has produced an amazing collection of images (also available as trading cards!) that show Earth’s change over time. The Earthshot collection has a wide variety of examples of change over time including:
– natural phenomena changes (glaciers, deserts,)
– social change (city growth,)
– human interaction with the natural world (mining, deforestation, agriculture,)
– natural disasters (hurricanes, tornado damage, flooding.)

Below are two examples of the trading cards, Mount St. Helens pre/post volcanic explosion and Las Vegas, Nevada population growth over time.

The cards provide side by side comparison images and also context about the images on the opposite side including information about the date of the images, satellites, bands used to create the images and location data.

If you view a location on through the browser you will get about 5 images you can review as well as context about the images.
