This map shows water extent along the Missouri River and surrounding regions on May 29th, 2019. Areas with likely flooding detected are shown in red.
The NASA Disasters Program responded to a request from the USDA National Agricultural Statistics Service (NASS) to provide water extent maps for the regions affected by the recent flooding rainfall in the central U.S. Maps were generated using Sentinel 1A/B satellite overpasses of the central U.S. from 5/22/19 to 6/17/19...

ARIA Damage Proxy Map Using Sentinel-1
The Advanced Rapid Imaging and Analysis (ARIA) team at NASA's Jet Propulsion Laboratory in Pasadena, California, created this Damage Proxy Map (DPM) depicting areas of Florida and Georgia that are likely damaged (shown by red and yellow pixels) as a result of Hurricane Michael. The map is derived from synthetic aperture radar (SAR) images from the Copernicus Sentinel-1 satellites, operated by the European Space Agency (ESA). The pre-event images were taken before...

ARIA damage proxy map derived from images taken before (September 02, 2016) and 12 hours after the hurricane's landfall (September 14, 2018 7:06 PM local time).
UPDATE 9/18/18:ARIA damage proxy map derived from images taken before (September 02, 2016) and 12 hours after the hurricane's landfall (September 14, 2018 7:06 PM local time). The ARIA team has created a flood extent map from Sentinel-1 SAR data acquired from Track 4, 12 hours after the landfall of Hurricane Florence. The map was pushed to the FEMA's SFTP server and is available to download from  ...

Sentinel 1A overpass of coastal North and South Carolina from 9/14/18. Contains modified Copernicus Sentinel data (2017), processed by ESA. 
Sentinel 1A overpass of coastal North and South Carolina from 9/14/18. Contains modified Copernicus Sentinel data (2018), processed by ESA.  Mission description: Sentinel 1A/B is a two satellite synthetic aperture radar constellation operated by the European Space Agency. The backscattered microwave energy from the ground can be used to map flooded areas, and estimate wind speeds over the ocean. Both satellites have a 12-day repeat cycle, providing imagery at about 20m resolution every 6...

Flood map for Kerala
In the maximum observed flooding map, areas in RED are flooding mapped from Copernicus Sentinel 1 SAR data provided by the European Space Agency. Areas in PURPLE are currently flooded and also flooded in previous years. Areas in BLUE are covered by a reference normal water extent. Areas in LIGHT GRAY are all previously mapped flooding, since 1999. The...

Satellite-Derived Map of Ground Deformation from Earthquake beneath Lombok, Indonesia
Scientists with the Advanced Rapid Imaging and Analysis project (ARIA), a collaboration between NASA’s Jet Propulsion Laboratory in Pasadena, California, and Caltech, also in Pasadena, using synthetic aperture radar (SAR) data from the European Union’s Copernicus Sentinel-1A and -1B satellites, operated by the European Space Agency, generated a map of the deformation of Earth’s surface caused by the Aug. 5, 2018 magnitude 6.9 earthquake under Lombok island, Indonesia. The deformation map is produced from automated interferometric processing of the SAR...

Motion towards satellite (up and west) in radar line-of-sight direction.
Interferogram from modified Copernicus Sentinel-1 SAR data acquired 2018/02/17 and 02/05 shows earthquake fault slip on subduction megathrust beneath coast caused up to 40 cm of uplift of the ground surface. Interferometric SAR (InSAR) analysis was automatically performed by Caltech-JPL ARIA data system. Main image shows motion towards satellite (up and west) in radar line-of-sight direction. Additional images show motion contoured with 9 cm (image 2) and 2.8 cm (image 3) color contours, also known as fringes, displayed in Google Earth. Symbols show preliminary USGS and Mexican seismic...

LAOS Dam failure
On July 25, 2018, the Sentinel-1 satellite from the European Space Agency (ESA) Copernicus program captured a clear image of the collapsed Xe-Pian Xe-Namnoy dam and resulting floods. The imagery within the map viewer shows a drastic drop in the reservoir level, the impacts of which were felt on villages downstream.  NASA and SERVIR-Mekong processed satellite imagery to estimate the extent of the flooded areas, particularly along the Xe Pian River and village of Sanamxai along the Xe Khong River in Attapeu province. Since the dam failure on July 23, cloudy skies have...
