OLI

Overview

The spectral bands of the OLI sensor, while similar to Landsat 7’s ETM+ sensor, provides enhancement from prior Landsat instruments, with the addition of two new spectral bands: a deep blue visible channel (band 1) specifically designed for water resources and coastal zone investigation, and a new infrared channel (band 9) for the detection of cirrus clouds. A new Quality Assurance band is also included with each data product. This provides information on the presence of features such as clouds, water, and snow.

Landsat 8 OLI image prior to flooding on 7/14/17.  Landsat 8 OLI image after flooding from Hurricane Florence, acquired 9/19/18. USGS's Operational Land Imager (OLI) on the Landsat 8 satellite has captured optical imagery of devastating flooding in the Carolinas from Hurricane Florence. NASA scientiets are using this imagery to help state and local...

lava flow dynamics slide 1
These images show lava observations from USGS helicopter thermal imagery and the NASA Landsat 8 and ESA Sentinel 2B satellites. The lava flow speed was calculated for the channel which opened on May 22nd from fissure 6 and 18 which reached the ocean sometime between May 23rd and May 24th. Using two satellite overpasses 12h 37min apart and the position of  the head of the lava flow from LandSat 8 and Sentinel 2B, the inferred mean flow was near 2.6 m/min. ...

Landsat 8 image aquired June 24th, 2018.
Landsat 8 image aquired June 24th, 2018. On June 3, 2018, torrents of hot ash, rock, and gas poured down ravines and stream channels on the slopes of Volcán de Fuego—Guatamala’s Volcano of Fire. More than three weeks after the eruption, the Landsat 8 satellite continued to detect elevated temperatures in some of the pyroclastic flow deposits. The avalanches...

Mt. Fuego eruption
  It is one of Central America’s most active volcanos. Volcán de Fuego puffs continuously without notice by nearby communities, punctuated by episodes with explosive activity, huge ash plumes, and lava flows. The Guatemalan volcano is at it again, beginning its latest bout of unruly behavior on January 31, 2018. On the next day, the Operational Land Imager (OLI...

Landsat 7 image of flooding near near St. Peters, Missouri on May 9th, 2017.
Landsat 7 image of flooding near near St. Peters, Missouri on May 9th, 2017. Landsat 8 image showing the same area on April 28, 2016 for comparison. In late April and early May 2017, heavy rains in the Midwest gave way to rising rivers and flooding. These false-color images from Landsat satellites show one affected area near St. Peters, Missouri, northwest...

On January 24, 2017, the Operational Land Imager (OLI) on the Landsat 8 satellite acquired this false-color image of scorched land flanked by actively burning fires.
On January 24, 2017, the Operational Land Imager (OLI) on the Landsat 8 satellite acquired this false-color image of scorched land flanked by actively burning fires.  Wildfires continued to ravage Chile’s countryside in early February 2017, weeks after they flared up in mid-January. The blazes have thwarted firefighters’ efforts to control them, with new hot spots emerging daily. Satellite data and scientific analysis suggest the fires are among the worst the country has seen in...

The Operational Land Imager (OLI) on the Landsat 8 satellite captured this image of flooded land near the Pra River on January 9, 2017. This second image shows the same area on February 2, 2014, when waters were lower. Several days of heavy rainfall swamped much of southern Thailand in January 2017. While monsoon-related floods are common in Thailand, the wet...

The Operational Land Imager (OLI) on the Landsat 8 satellite captured this natural-color image of a smoke plume south of Río Colorado on December 29, 2016.
The Operational Land Imager (OLI) on the Landsat 8 satellite captured this natural-color image of a smoke plume south of Río Colorado on December 29, 2016. Dense smoke rose above a rash of wildfires in the Pampas region of Argentina in late December 2016 and early January 2017. Over the past month, roughly two dozen fires have spread across the rural landscape. The blazes were likely started by thunderstorms that followed a stretch of hotter-than-average weather, according to ...

Hazardous Landslide-dammed Lake, Pisang, Annapurna Region, Nepal
The April 25, 2015 magnitude 7.8 Gorkha earthquake in Nepal produced a landslide dam on the Marshyangdi River, 1.1 miles (1,800 meters) upstream from the village of Lower Pisang. The dam has impounded the river, produced a landslide-dammed lake extending approximately 1,722 feet (525 meters) up the river, and satellite imagery shows that the lake area is expanding with time. Landslide dams can be inherently unstable and may fail suddenly, leading...
