Wanting to bring the benefits of technology into your earth science classroom? Dive into the treasure trove of satellite images that Landsat makes available everyday!
What is Landsat you may ask? “Landsat represents the world’s longest continuously acquired collection of space-based moderate-resolution land remote sensing data.” Meaning it is almost 40 years straight of images of earth from satellites. And the best part of it all…you can access them all! * to learn more about Landsat check out their About Landsat page
I think the easiest way to dive into these data are through the EarthExplorer interface. Here you can search the data first by location, either by knowing an exact address or place name OR by putting in a feature. Then you can select what timeframe you want to see the images from.
You can search locations:
- around natural disasters before and after to see the changes.
- that are getting warmer over time and look for other changes.
- around your school from the first month of school each year going back as long as you have been there!
Enjoy bringing the technology of satellites and seeing things from space into your lessons!
* If you are interested in seeing how scientists use satellite images in their work and how to connect your students with that, check out Dr. Ellyn Enderlin’s Polar-ICE Data Story “How and why are glaciers changing over time?” (there is a webinar recording, datasets, and lesson plans on the Polar-ICE Data Story page that accompany this resource).
