Images of Change provides a user-friendly mobile interface for exploring an extensive gallery of land-based and space-based images showing dramatic change over time on Earth. Hosted on NASA’s Global Climate Change website, Images of Change is designed to raise awareness of climate change, inspire curiosity and interest in the programs that create the images, and highlight the importance of global climate change research.

The app offers a tablet viewing experience that feels natural in a touchscreen environment. Each image is available in three viewing methods (curtain, thumbnails, and side-by-side). The interface responds to the tap, pinch, and drag gestures familiar to Apple iPad users.

The app requires iOS 4.3 or higher for iPhone, iPad, and iPod Touch devices.

This work was done by Austin J. Fitzpatrick, Nancy J. Leon, Randal K. Jackson, Amber H. Jenkins, William M. Greene, Alexander Novati, and David Woldenberg of Caltech; and Justin M. Moore for NASA’s Jet Propulsion Laboratory. For more information, contact This email address is being protected from spambots. You need JavaScript enabled to view it..
