Why this webinar?

Interferometric Synthetic Aperture Radar (InSAR) is a powerful technique that allows for the analysis of Earth’s surface motions caused by both natural and anthropogenic processes. However, the processing of large SAR datasets needs large in-house processing resources.

That’s where EarthConsole® steps in.

EarthConsole® is Progressive Systems’ cloud-based platform that helps institutions, researchers, and developers create, test, and host applications and processors, enabling simplified access to Earth Observation data and processing services. By co-locating computing resources with data archives, the platform ensures faster and more efficient data processing.

During the webinar we present an overview of the InSAR theory and show the application of the P-SBAS on-demand service for Sentinel-1 (2016–present) and ENVISAT (2002–2012) hosted on the EarthConsole® platform to produce time-series of incremental ground motions and maps of the average velocities. A particular focus will be given to the study of ground deformation caused by both natural and anthropogenic processes. A demonstration will guide participants through the request and practical use of the service, with a particular emphasis on the graphical user interface (GUI) and processing parameters.

At the end of the webinar the attendants will be acquainted with the InSAR principles, as also with the procedure to request the P-SBAS service and process their own data on EarthConsole®.

EarthConsole® Stories: monitoring sand dams’ impact on water availability with satellite image time-series analysis

/in , /by

EarthConsole® Stories are experiences about how we helped universities, research centres or service developers to leverage Earth Observation data to extract valuable insights for their research, educational or pre-commercial projects.

The Project

Climate change driven by human activity is significantly altering the water cycle at global, regional, and local levels, with these effects expected to intensify in the coming years (Pörtner et al. 2022). In semi-arid regions, prolonged dry periods and high evaporation are already reducing the availability of usable water in river systems, with direct negative consequences for ecosystems and the livelihoods of local communities (Kalele et al. 2021).

Currently, around 1.5 billion people live in semi-arid areas and this number is expected to increase due to shifts in climate zones. To ensure their food security and counteract the impending water shortage, measures are necessary on different spatial and temporal scales. A comparatively simple and cost-effective method is the construction of dams along the flow cross-section of seasonal rivers. These act as natural barriers and within a few years fill up with sediment, in which the water collects and is protected from evaporation and too rapid runoff.

Led by Dr. Andreas Braun from the University of Tübingen, this research project aims to assess the impact of sand dams on water availability in selected African regions. Using time series analysis of satellite images, the study seeks to quantitatively and qualitatively evaluate how sand dams influence their surrounding environments.

The Need

To conduct this research, the research team needed advanced Earth Observation (EO) tools capable of analyzing long-term surface changes around sand dams. These dams gradually alter ground levels, leading to positive environmental effects such as for example increased soil moisture, enhanced vegetation growth, and reduced land degradation.

However, conventional EO approaches often struggle to capture changes in seasonal river systems, requiring the use of indirect indicators like vegetation cover and land-use modifications. To overcome this limitation, the team sought a solution that could track changes through closely spaced time series observations.

Why EarthConsole®

EarthConsole® was selected for its access to the P-SBAS (Parallel Small BAseline Subset) on-demand service for Sentinel-1, provided by IREA-CNR. This service implements an advanced InSAR technique enabling the generation of Earth surface deformation time-series and, more generally, interferometric products through an intuitive graphical user interface (GUI). The GUI allows the user to select SAR data for specific areas and time periods, set processing parameters, and download processing results autonomously.

Reflecting on his experience, Dr. Braun shared:

EarthConsole®’s P-SBAS for Sentinel-1 on demand service has been selected to enrich our research. In addition to Sentinel-2, US Landsat Missions and hyperspectral data such as EnMap, we wanted to explore the potential of Sentinel-1 SAR data to provide new insights into deformations caused by water extraction but also increased storage volume near the identified sand dams.

Dr. Andreas Braun, Academic Researcher, University of Tübingen – Germany

 

The Impact

This research has the potential to transform the use of sand dams as a climate adaptation strategy. It is based on the hypothesis that sand dams have a positive effect on their environment, but that this effect varies depending on the climate zone and landscape. By incorporating satellite-based monitoring, the project aims to showcase how sand dams can effectively mitigate water shortages, helping local communities build resilience against climate change.

This project has been supported via the ESA Network of Resources initiative.

Advancing Polar Research: the conclusion of the OCRE CryoSSARinSAM+ Project

/in , , /by

We are pleased to announce the conclusion of the CryoSSARinSAM+ project, an initiative funded by the European Commission’s OCRE (Open Clouds for Research Environments) program. Led by the Technical University of Denmark (DTU), the project set out to produce a single, open-access CryoSat-2 altimetry mission dataset created to become the reference standard for the radar altimetry research community to advance the knowledge of the polar oceans and ice cover, and the impact of climate change on them.

EarthConsole® by Progressive Systems, selected by DTU as service provider, supported the processing of these data and established a repository where researchers can now easily access and download the dataset.

Why Polar Regions Matter

The polar regions have always been a focal point for scientific research, and in today’s world, the need to monitor them has never been more urgent. With the accelerating effects of climate change, the melting of polar sea-ice is one of the most significant amplifiers of global warming with decreasing albedo. This makes tracking changes in the polar oceans essential for understanding long-term climate patterns, the opening of new arctic shipping routes, and the broader impact on the global ecosystem.

For years, different research groups independently processed CryoSat-2 radar altimetry data for the polar oceans, mainly covering the period 2010–2020. While these datasets were valuable for studying changes in these regions, the lack of coordination among the different research groups meant the data was fragmented. This project aimed to provide a more unified approach, also expanding the temporal and geographical coverage of these dataset.

The Expanded Cryosat-2 Dataset

The CryoSSARinSAM+ project aimed to grow and expand this vital dataset to create an Arctic and Antarctic dataset with full coverage from 2010-2024 for the Arctic region (50N-90N) and the Antarctic region (90S-50S).

The project added processing of C2 to create such. By using SARvatore for CryoSat-2 and SARINvatore for CryoSat-2 processors, the project focused on the:

  • the Subarctic region (180.00W, 50.00N, 180.00E, 65.00N) for the winter months from October 2010 to December 2020, as well as full-year data from 2021 up to January 2022, and
  • the Arctic (180.00W, 50.00N, 180.00E, 90.00N) and Antarctic (180.00W, 80.00S, 180.00E, 50.00S) regions from February 2022 up to September 2024.

A powerful dataset for many applications

The new CryoSat-2 dataset generated by the CryoSSARinSAM+ project holds immense potential for a wide range of applications. Some of the key areas of focus include:

  • Sea Level and Circulation: studying trends in sea level rise and ocean circulation in the polar regions.
  • Ice Thickness: estimating winter and summer sea ice thickness in the Arctic and Antarctic Ocean.

The dataset is designed to support a variety of research and monitoring efforts, and contribute to the global effort to understand and mitigate climate change.

Accessing the data: The Altimetry Virtual Lab repository

To download the CryoSat-2 dataset for free and explore its potential applications, simply:

  1. Register or login to EarthConsole®
  2. Request a free membership to the Altimetry Virtual Lab

These services support data processing from L1A (FBR) products to SAR/SARin L2 geophysical products.

Beyond processing services, this virtual space also offers tools to facilitate the exchange of scientific knowledge, data, and resources.

Looking Ahead

The conclusion of the CryoSSARinSAM+ project marks a significant milestone in the ongoing exploration of Earth’s polar regions. We are excited to see how this expanded dataset will contribute to the growing body of knowledge about polar oceans, ice dynamics, and sea level change.

Reducing Time Spent on Preparing Earth Observation Data: ARD for ENVISAT MERIS FR now on EarthConsole®

/in , , /by

Preparing Earth Observation data for processing can be a time-consuming and complex task, requiring technical expertise or access to an in-house processing infrastructure which may not always be readily available. This is where Analysis Ready Data (ARD) becomes increasingly valuable, above all for non-EO experts. ARD simplifies the process by providing pre-processed, georeferenced and harmonized datasets that are ready for immediate use. By eliminating the need for complex data preparation, ARD ensures consistency and comparability across time and space, allowing scientific users to move quickly to deriving insights for their research.

Introducing ARD for ENVISAT MERIS FR on EarthConsole®

To facilitate the scientific community’s use of Earth Observation data, EarthConsole® now offers a new processor designed to generate Analysis Ready Data (ARD) from MERIS, an instrument onboard ENVISAT satellite that collected data about ocean colour, atmosphere and land surface between 2002 and 2012.

Developed by us at Progressive Systems, the company behind the EarthConsole® platform, the ARD for ENVISAT MERIS FR processor automates the process of accessing and preparing this data. It downloads the needed MERIS data directly from ESA dissemination service, then creates a subset based on the region of interest.

The subset is collocated per pixel with respect to a master image (raster or re-projected onto a Coordinate Reference System).

Time series of four MERIS L2 images acquired over northern Italy from August 2002 to July 2003. The subsets are collocated and refer to the band 13 TOA reflectance.

All of this is done using EarthConsole® parallel processing environment, which optimizes data access by leveraging the co-location of computing resources with the data archives.

This processor is critical for tasks like tracking changes over time (multi-temporal analysis) or artificial intelligence applications, where each image needs to be georeferenced and comparable at the pixel level. Thematically, this tool can be applied to a wide range of research areas, ranging from vegetation to water quality and land use studies.

The value of this tool increases even further when its outputs are combined with data from active Earth Observation missions, enabling even more comprehensive analysis on long-term environmental trends.

Practical Applications

The ARD for ENVISAT MERIS FR tool is already being used in important research projects, like the ESA River Discharge Climate Change Initiative. This project focuses on studying rivers worldwide and how their flow patterns are changing over time due to climate change.

Using this tool, 25,000 satellite images were processed, focusing on 45 specific locations around the world. The tool automatically prepared smaller, targeted datasets (about 72,000 in total) for these locations. These prepared datasets were then ingested in a machine learning model developed by the project team. To learn more, you can read our EarthConsole® Story on tracking and predicting changes in river systems with ENVISAT data.

Coastal and Open Ocean Altimetry Data: How ALES unlocks insights from 1995 to today on EarthConsole®

/in , , /by

In the world of satellite altimetry, precision is key. For years, satellites have revolutionized how we measure sea levels, monitor ocean currents, and track environmental changes.

But there’s been one tricky area for researchers: coastal regions.

Historically, satellite altimeters have struggled to provide reliable data near coastlines.

That’s where ALES — the Adaptive Leading Edge Subwaveform retracker — available on EarthConsole® comes in, offering a new way to make accurate altimetry measurements.

What is ALES and why should you care?

ALES is a subwaveform retracking algorithm developed by Marcello Passaro from the German Geodetic Research Institute of the Technical University of Munich, to overcome the challenges altimeters face when measuring sea levels close to the coast.

ALES improves the accuracy of satellite data near coastlines, all while maintaining high accuracy in open ocean measurements, making it a relevant tool for scientists, oceanographers, and anyone tracking sea level rise or coastal changes.

How Does ALES Work?

To understand how ALES functions, let’s start with how satellite radar altimetry works.

Satellites send out radar signals that bounce off earth surface and catch the echoes as they bounce back. The time it takes for these signals to return helps calculate the distance to the surface, allowing us to determine for example sea level. While this process is straightforward in open waters, it becomes complicated near the coast due to interference from land or other reflective objects like for example ship traffic.

ALES works by looking at the signals the satellite gets back and focusing on a specific part of each signal – the leading edge. From this section, ALES makes a rough estimate of how tall the waves are. This information is important because knowing the wave height helps improve the accuracy of the data.

Once ALES has the wave height estimate, it can choose the best part of the wave signal to analyze. By narrowing its focus, ALES can avoid interference from other factors, such as reflections from land or ships. This targeted analysis helps to eliminate noise and enhances the quality of the data, resulting in more precise measurements of sea level.

ALES on EarthConsole®

You can now access an extensive time series of altimetry data spanning from 1995 to today, thanks to the addition of the bulk processing option for ALES for Envisat and ERS-2 data (both missions no longer operational in space) via the Heritage Missions Virtual Lab on EarthConsole®.

This addition complements the existing ALES+ SAR service for Sentinel-3 and CryoSat-2, which was already available for both bulk and on-demand processing via the Altimetry Virtual Lab on EarthConsole®.

This will provide you with a clearer understanding of how coastal zones and open ocean conditions have evolved over the last three decades.

Getting started with ALES for ENVISAT or ALES for ERS-2 (FREE ACCESS):

  1. Log in to www.earthconsole.eu.
  2. Request a free membership to the Heritage Missions Virtual Lab www.earthconsole.eu/groups/heritage-missions.
  3. Click on the card ‘Request the service you need’ and submit the service request using the dedicated form within the Lab.
  4. Wait for approval; it may take a few days as we process your request with ESA.
  5. Once approved, you’ll receive 100 free processing hours, which can be renewed for another 100 hours pending ESA approval.

What makes ALES stand out is its adaptability and versatility.

Whether it’s applied to older satellite missions like ERS-2 and Envisat, or the latest missions like CryoSat-2 and Sentinel-3, ALES is applicable to waveforms from different altimeters. This flexibility enables to extend the time series and ensures that we can analyze both historical and current satellite data to better understand sea level changes over time.

If you’re interested in finding out whether ALES is suitable for your research, feel free to contact us at info@earthconsole.eu.

EarthConsole® Stories: GPU-powered SAR back-projection fully focused processor for enhanced S6 altimetry data processing

/in , /by

EarthConsole® Stories are experiences about how we helped universities, research centres or service developers to leverage Earth Observation data to extract valuable insights for their research, educational or pre-commercial projects.

The Project

In the frame of the Sentinel-6 Poseidon-4 Ground Processor Prototype project, a Synthetic Aperture Radar (SAR) back-projection fully focused processor for Sentinel-6 (S6) was developed which processes all the chains starting from the altimeter source packets up to the Level 1B.

This processor had a major limitation: its run-time performance was too slow to be used for operational purposes. To address this, the research team decided to employ a dual strategy: optimizing the algorithm and leveraging the computational power of Graphics Processing Units (GPUs).

They successfully developed this improved processor in November 2023, which was a big step forward for the project.

Initial tests showed very promising results, showing that the processor running on GPUs has a run-time performance improvement of over 50 times with respect to the one running on CPUs. In the final phase of the project, the need arose to thoroughly test both the scientific accuracy and the run-time performance of the processor. This required a dedicated machine with specific configurations, a need which was met by EarthConsole®.

The Need

The main need was to find a robust and efficient processing environment to fully utilize the processor’s potential. The team required a high-performance computing solution to finalize the software and run tests using Sentinel-6 data. Following this phase, the intention was to perform a full 10-day cycle of S6 data with multiple configurations optimized for various surface types to verify how well the processor worked across various conditions. Finally, the generated data had to be analysed and assessed in comparison with existing operational data.

Why EarthConsole®

The decision to resort to EarthConsole® was driven by its ability to meet our computational needs, offering GPU-equipped virtual machines essential to test our processor’s optimized performance. These virtual machines with GPUs are not yet available within the European Space Agency’s (ESA) existing infrastructure. This enabled us to achieve improvements in run-time performance and scientific accuracy for our SAR back-projection processor

Marco Fornari, Ground Segment Engineer at RHEA for ESA – European Space Agency 

 

The Impact

The impact of this project extends far beyond the immediate improvements in processing efficiency for Sentinel-6.

The knowledge acquired with this project will have significant implications for future missions as well, such as CRISTAL and Sentinel-3 Next Generation Topography (S3NG-T), where similar processing capabilities will be essential.

EarthConsole® Stories: Tracking and predicting changes in river systems with ENVISAT data

/in , , /by

EarthConsole® Stories are experiences about how we helped universities, research centres or service developers to leverage Earth Observation data to extract valuable insights for their research, educational or pre-commercial projects.

The Project

The ESA River Discharge Climate Change Initiative aims to generate long-term climate data records—spanning at least 20 years—of river discharge for selected river basins and key locations within their networks. This will be achieved using satellite remote sensing observations, including altimetry and multispectral images, along with ancillary data. This data is essential for understanding the flow and behaviour of rivers in specific regions and at critical points along their courses. The goal is to develop a robust analytical tool capable of tracking and predicting changes in river systems resulting from climate change.

The Need

The research team, tasked with managing ENVISAT MERIS data spanning 2002 to 2012 from multiple global sites, required an efficient platform for handling this extensive dataset. They found the ideal solution in the Heritage Missions Virtual Lab, an ESA initiative hosted on EarthConsole®. This platform provides specialized processing services for data from discontinued Earth Observation missions like ENVISAT.

Beyond data access, the team needed to generate Analysis Ready Data (ARD) for the MERIS FR datasets. For this purpose, the EarthConsole® team developed a tool that automatically extracted time series data from approximately 25,000 MERIS FR Level 2 products, targeting specific stations within 45 worldwide sites. This process produced around 72,000 subsets, which were subsequently utilized in the neural network model developed by the team.

Why EarthConsole®

The EarthConsole® G-BOX hosting service via the Heritage Missions Virtual Lab was the research team’s choice for direct access to ENVISAT Meris data.

The service was used to process Analysis Ready Data for large ENVISAT MERIS FR datasets for 45 sites worldwide with our own neural network model. In fact, the processing of the huge number of images from 2002 to 2012 would have been too time consuming to be handled on our local infrastructure. The EarthConsole® hosting service was used to speed up the process and provide a consistent and practical method to process the multi-temporal analyses to be later on compared with the in-situ river discharge

Paolo Filippucci, Researcher at IRPI CNR – Italy

 

The Impact

The ESA River Discharge Climate Change Initiative will greatly benefit the research community and society by using advanced satellite technology to monitor and analyse river ecosystems over time. This project provides crucial data on river flow and behaviour, helping to track and predict changes due to climate change. Researchers, environmentalists, and policymakers will gain valuable insights, enabling better decision-making for sustainable water management and climate resilience.

This project has been supported via the ESA Network of Resources initiative.

Investigating Earth surface displacement with the on-demand P-SBAS service for Sentinel-1

/in /by

Our planet continually undergoes transformations, with natural and human-induced displacement shaping its surface. Comprehending these changes is paramount across various disciplines, from environmental science to disaster preparedness and response.

Fortunately, advancements in satellite technology have provided us with tools to detect and study the Earth’s surface dynamics.

In particular, the Differential Synthetic Aperture Radar Interferometry (DInSAR) technique permits to measure the deformation component along the radar line of sight (LOS) with a very large spatial coverage capability and with accuracy of a fraction of the wavelength relevant to the transmitted microwave signals. This result is achieved by exploiting the phase difference (interferogram) between pairs of complex SAR images, usually referred to as single look complex (SLC), which are acquired by the SAR sensor at different times.

Furthermore, over the last 30 years advanced DInSAR approaches, which allow the retrieval of the temporal evolution of the detected surface deformations by exploiting large multitemporal SAR data sets, have been developed. Among these, the Small BAseline Subset (SBAS) technique developed at IREA – CNR (Italian Institute for Electromagnetic Sensing of the Environment), offers the possibility to compute displacement time series and the corresponding mean deformation velocity map with centimeter to sub-centimeter accuracy.

The SBAS approach has emerged as particularly effective to investigate ground displacements both in natural and anthropogenic hazard contexts, such as volcanoes, earthquakes, landslides and human-induced deformation due to mining activities, fluids exploitation, and large infrastructures construction.

Moreover, in 2014, a parallel version of the SBAS algorithm, referred to as the P-SBAS approach, was developed. This implementation is able to properly exploit distributed computing infrastructures, such as grid and cloud computing (CC) environments.

In this context, the P-SBAS algorithm, specific for the Sentinel-1 data processing, has been released as an on-demand web-based tool by integrating it within the EarthConsole® platform.

The on-demand P-SBAS service for Sentinel-1 represents a collaboration between IREA-CNR and Progressive Systems’ EarthConsole® platform, bridging the gap between advanced satellite monitoring and end-users.

This service empowers users to investigate surface displacement autonomously.

Through the intuitive EarthConsole® interface, users can select the SAR data to be processed over their area of interest, set the input parameters for the processing, and download processing outputs once ready.

How to access the on-demand P-SBAS for Sentinel-1 service

Interested users can request the service by completing all parts of the P-PRO ON DEMAND form on the EarthConsole® webapp.

REQUEST THE SERVICE

The information collected through the form serves as a basis to help you prepare a sponsorship request for the ESA Network of Resources. If approved, the sponsorship covers the cost of using the service for up to 500 processing hours over six months.
