Images from Landsat 8's Operational Land Imager sensor show the dramatic transformation of the river as it flows toward Cedar Rapids. On July 8, 2016, the shallow river meanders into the city, surrounded by green crops in the heart of the growing season.

Algal blooms occur annually on Milford Lake in the summer and can be harmful to fragile wetland ecosystems. The USGS Kansas Water Science Center uses multispectral sensors on board drones to identify harmful algal blooms and study how they affect local businesses and human and animal health.

A large infrastructure project has changed the shape of the coastline of the Netherlands while increasing the cargo capacity at Europe's largest port. This pair of Landsat images spanning 15 years shows the Maasvlakte 2 project, which is an expansion of the Port of Rotterdam.

Images from Landsat 5 in 1993 and Landsat 8 in 2016 show how the Yangtze river transformed after the completion of the largest hydroelectric power plant in the world in 2012. 

Mining has been part of Center's history for more than a century. In August 1984, the Landsat 5 image shows significant surface mining of lignite coal just to the southeast of town, during a summer when drought had browned the countryside. Thirty-two years later, the mining activity moved to the southwest of Center.

A wildfire near Soberanes Creek along the Pacific coast of California started July 22, 2016, and spread to over 86,000 acres one month later. Landsat images from July 13, July 29, and August 14 show the dramatic progression as active fire burns orange in the latter two scenes, and smoke appears as a blue haze.

On June 28, 2016, a 4,000-foot-high mountainside in Glacier Bay National Park and Preserve collapsed, sending rocky debris equivalent to 60 million mid-size SUVs tumbling onto nearby Lamplugh Glacier.

Earth observation satellites help researchers confirm the presence of large plumes containing suspended sediments extending from hundreds of wind towers in the coastal waters of the North Sea southeast of England.

Landsat image taken in 1992 shows the Uinta Mountains east of Salt Lake City. The shades of dark green indicate healthy, undisturbed forest. Landsat image of the same area in 2010 captures the dramatic assault of mountain pine beetles. The dark red stains reveal widespread pine beetle destruction.

Massive defoliation caused by a severe outbreak of the European gypsy moth caterpillar during the spring and summer of 2016 across southern New England and the Mid-Atlantic was easily captured by the Landsat 8 Operational Land Imager sensor from 438 miles in space.

In September 1964, Interior Secretary Stewart Udall successfully shepherded some of the most remote and rugged terrain within the continental United States into the jurisdiction of the National Park Service (NPS) with the creation of Canyonlands National Park in southeastern Utah.

The end of Kaskawulsh Glacier lies at a drainage divide. Before spring 2016, the majority of the glacier's meltwater flowed north by way of the Slims River into Kluane Lake, and from there into the Yukon River and to the Bering Sea.

Remotely sensed imagery of wildfires burning in the Siberia region of Russia shows the complementary possibilities of Landsat 8 and NASA's ASTER sensor aboard its Terra satellite.

Cracking ice on the Arctic Ocean fractures like broken glass in far northern Canada. Uninhabited Eglinton Island is the land on the right. Fingers of land from Prince Patrick Island stretch downward in the upper left of the image.

These Landsat images show logging’s influence around the dark green protected forests. Many of the small pink spots in the lower left corner and across the right side of the 1984 scene are logging sites revealed through Landsat 5’s Thematic Mapper sensor.

Pre- and post-fire images acquired with shortwave infrared (SWIR), near infrared (NIR), and red bands on Landsat 8’s Operational Land Imager sensor reveal a significant, 14,442-acre burn scar within the park’s high country. The burn scar appears red in the June 23 image.
