Creating a Time Series Visualization of Two Decades of Changes in a Glacier

NASA has created a time series visualization of Greenland’s Helheim Glacier using 20 years of data from radar, lasers, and high-resolution cameras.

Sudden Landslide Identification Product (SLIP) developed by NASA detects landslide potential by analyzing satellite imagery for changes in soil moisture, muddiness, and other surface features. The Landsat 8 satellite capture the left and middle images on September 15, 2013, and September 18, 2014—before and after the Jure landslide in Nepal on August 2, 2014. The processed image on the right shows areas in red indicating a probable landslide and areas in yellow showing a possible landslide.
