Risk Mapping

Web Content Image

Identifying risks on land and in water can be a vital tool for prevention and for providing solutions. Satellites can provide invaluable views from a higher perspective, and help to analyse risks.

Sentinel-1's SAR mission supports urban deformation mapping.

Sentinel-3's SLSTR instrument supports Land Monitoring applications including Risk (i.e. Fire Location and Radiative Power), and Forestry (i.e. NDVI generation and Land Surface Temperature (LST)). More on Sentinel-3's Land Monitoring applications can be found in the User Guide.

Thematic Results

Following the appearance of a large crack in the ice shelf close to the Halley VI research station in Antarctica, information from the Copernicus Sentinel-1 and Sentinel-2 satellites helped to decide to close the base temporarily.

With the new Earth observation satellites carrying a range of technologies such as radar and multispectral imaging instruments for land, ocean and atmospheric monitoring, data are available for the next 20-30 years. However, this means little unless there are capable people handling them.

In this study the team show the usefulness of InSAR for examining surface deformation due to groundwater withdrawal and recharge in Phoenix, Arizona. Multi-track ascending and descending ERS SAR datasets from 1992-1996 and Envisat ASAR, 2003-2010 are combined to obtain vertical and horizontal (east-west) displacement time series components.

Developers of apps that use satellite data to assist the agricultural industry took home the top two prizes at this year's ESA App Camp in Barcelona.

Sentinel-1A has added yet another string to its bow. Radar images from this fledgling satellite have been used to map the rupture caused by the biggest earthquake that has shaken northern California in 25 years.

Calling all app developers: register today for the opportunity to spend a week at ESA developing new ideas and concepts for mobile apps using satellite Earth observation data.

As ESA and China mark a decade of cooperation, imagery over China's Poyang lake is testament to the new Sentinel satellite's promise of continued radar data acquisition for a multitude of applications.

From climate change monitoring to supporting humanitarian aid and crisis situations, early data applications from the month-old Sentinel-1A satellite show how the radar mission's critical observations can be used to keep us and our planet safe.

Twenty years of radar coverage from ESA satellites have been used to measure the rapid thinning of Antarctica's Pine Island Glacier - and it's losing more ice than previously thought.

The SBAS-DInSAR technique has been applied to ERS, Envisat and COSMO-SkyMed data to analyse and model the Ivancich landslide, Assisi, Central Italy.

Sentinel-1A, Europe's first satellite for Copernicus, is almost ready for launch on 3 April. Meanwhile, ESA is showing how its advanced radar will map ice, monitor subsidence and much more.

In this study the scientists use Envisast ASAR data to investigate coseismic and post-seismic surface deformation associated with the 2008 Mw 6.3 Damxung earthquake on the Tibetan Plateau.

In this study the team combined time-dependent gravity and DinSAR ground deformation measurements demonstrating that are complementary to each other and their regular recording may disclose and clarify complex volcanic dynamics.

A navigation system for self-driving vehicles that uses satellite radar data has won the top prize in the European Earth-monitoring competition.

With water security being one of Africa's biggest challenges, ESA's TIGER initiative is using satellite observations to provide local authorities with the information they need to develop this vital resource.

This research focus on the method termed here, the Intermittent Small Baseline Subset (ISBAS), which, compared with the Small Baseline Subset (SBAS) method, appears to improve results over natural, woodland and agricultural terrain.

The Santorini caldera has been a source of numerous eruptions and tsunamis in the past with the most recent seismic sequence ending in 1950 .Since then, Santorini volcano was in a "quiet" phase, with insignificant deformation and limited seismic activity.

In this study the team use geodetic data to determine surface deformation associated with the Mw 5.1 earthquake that occurred in Lorca, southeast Spain, on 11 May 2011.

In this study the team focuses on the Zhongba earthquake sequence, which occurred between 2004 and 2008 within the South Lunggar Rift in the southwest part of the Tibetan Plateau.

Those who need satellite data for a wide range of applications, from mapping sea ice and tracking maritime traffic to monitoring geohazards over land, are eagerly awaiting the launch of Sentinel-1. ESA is helping users get ahead of the game by offering test data and simulated images.
