New stories on change detection and ERS-2 re-entry in HEDAVI
Two new stories are now available in ESA’s HEDAVI (HEritage DAta VIsualisation) tool. HEDAVI visualises Earth observation data from satellites in ESA’s Heritage and Third Party Missions programme, and includes some data from the Copernicus Sentinel satellites.
Eruption of Mount Merapi Volcano (Indonesia), May-June 2006
See Mount Merapi's 2006 activity through Envisat satellite imagery, capturing the volcano's response to seismic events.
Deforestation in Brazil: A Satellite Perspective from 1992 to 2010
Explore multi-temporal satellite images showing deforestation across various regions of the Amazon rainforest in Brazil.
Deforestation in Riau Province (Sumatra Island, Indonesia), 2005

Space data support Earth’s ecosystems
ESA’s Earth observation (EO) missions are making a critical contribution to monitoring transformations in our planet’s ecosystems, helping track changes in the vegetation, soil, and ocean that affect these systems.
Tracking the world’s forests from space
As human activities continue to threaten the planet’s forests, data delivered by satellites are boosting global efforts to conserve these crucial natural resources.
Envisat data show how volcanoes communicate with each other
Using radar data from ESA’s Envisat mission, scientists have recently proven the elastic interaction between two Hawaiian volcanoes.
Remote sensing data underpin research on soil
Environmental data disseminated by ESA’s Earth observation programmes provide knowledge about the stresses on Earth’s soils – aiding many applications such as crop management, drought and flood forecasting, and ecosystem protection.
Meet a young researcher who studies the behaviour of volcanoes worldwide
Researcher Camila Novoa Lizama, of the University of Leeds, recently analysed how the use of Synthetic Aperture Radar (SAR) imagery over the Puyehue Cordón-Caulle Volcanic Complex, in Chile, acquired by ALOS-1, Envisat and the Copernicus Sentinel-1 satellites, helped her team to better comprehend the temporal and spatial behaviour of ground displacements before, during and after the volcano’s last eruption.
Transforming space data into climate action
ESA’s Earth observation activities are playing a key role in the revitalised global drive to combat climate change.
Data preservation takes centre stage at Living Planet Symposium
Against the backdrop of the famed Rhine River, world-class scientists and Earth observation data-users are gathered this week in the historical city of Bonn, at the Living Planet Symposium (LPS).
Introducing Mirko Albani
In this short introduction, ESA's Heritage Missions Programme Manager describes what he likes most about ESA's long term archive of satellite mission data and his role in the programme.
How Envisat helped to shape global understanding of Earth’s systems
Twenty years have passed since a ground-breaking European spacecraft designed to deliver unprecedented insight into the planet’s changing environment was lofted into orbit.
