NASA launches new App, “Images of Change”, featuring images of changing Earth

Washington, Dec 7 (): A new iPad app from NASA gives users a sight into how climate change and natural disasters are quickly changing the landscape of the Earth.

The new iPad app is called “Images of Change” and is free in the iTunes app store. It offers side-by-side images of areas on Earth that have altered over the years, mostly due to human activity.

John Grunsfeld, NASA’s associate administrator for science in Washington, DC said 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. And by using ground-based and space-based observation systems, they are able to better understand how humans are contributing to a changing world.

A changing climate, natural disasters and human activities are rapidly changing the face of our planet, NASA said. With the use of NASA’s Images of Change iPad application, users can get an interactive before-and-after view of these changes. The app offers pairs or sets of images of places around the world that have changed intensely.

Few of these locations have seen a disaster, such as a fire or tsunami, or demonstrate the effects of human activities, such as dam building or urban growth. Some others document effects of climate change such as persistent drought and rapidly fading glaciers.

Images of Change makes NASA climate change images, interactive tools and resources more accessible to the decision makers and citizens.

The image pairs are part of the larger Images of Change gallery on NASA’s Webby-award winning Global Climate Change website. The gallery comprises of satellite views and photos taken at ground level.

The users of the app can look at the images side-by-side or overlay them using a slider bar to travel from past to present. Each image pair comprises of background information on what the viewer is seeing and its location on a map.
