The Images of Change app displays before-and-after images of places that have sustained natural calamities, human activities such as urbanization and traces of climate change, NASA said Tuesday.
John Grunsfeld, NASA’s associate administrator for science based in Washington, said the app uses ground and space observation systems for users to see how humans have contributed to those changes.
“Images of Change gives users an astronaut’s or Earth explorer’s view of the changes occurring on our planet and demonstrates the important role NASA plays in contributing to the long-term understanding of Earth,” added Grunsfeld.
Each image is taken from NASA’s Global Climate Change website gallery, including satellite and ground level views and related information.
The app shows images both side-by-side and by overlaying the photos to navigate through different times.
