Our 2020 in Review

/in /by

2020 was an out-of-the ordinary year but, despite the unusual challenges, here at Progressive we were able to achieve important milestones made possible by the commitment and dedication of our Team and our Partners. Such projects have laid the foundations for exciting initiatives coming up in 2021, which we are looking forward to sharing soon.

These are the key highlights of our 2020:

January and February

We continued assisting the growing community of Earth Observation Altimetry data enthusiasts, in the frame of the ESA Research and Service Support – RSS, the ESA service we operate since 2006 dedicated to supporting the Earth Observation (EO) community in exploiting EO data.

We kicked-off 2020 by putting together several processing services for Sentinel-3 and CryoSat-2 developed over the years by different PIs, under a unified umbrella: the SARvatore Services (SAR Versatile Altimetric TOolkit for Research and Exploitation) family. This collection of services enabled more than 200 users to get Earth surface heights over ocean, inland water bodies, rivers or ice sheets.

March and April

Together with our partners Solenix, Qualteh JR, Terrasigna and GISAT, we released an updated version of the ESA Copernicus Sentinel App, the gateway to knowing the Copernicus Sentinel satellites. The App enables users to track the Sentinel satellite in orbit, search for products in a specific point over the 3D globe, visualize the latest product acquired from the satellite and save the searches. The new version is enriched with the possibility to browse Sentinel-5P products.

Additionally, during the same months, we furthered our work within the Sentinel-3 Mission Performance Centre by contributing to increase the level of quality and maturity of the new Copernicus S3 Fire Radiative Power (FRP) product derived from S3 Sea and Land Surface Temperature Radiometer (SLSTR). We supported the development of a new algorithm for the validation of S3 FRP SLSTR with the objective to measure with higher accuracy the radiative power of land and ocean hotspots (wildfires, volcanoes, agricultural burning etc.) over an area size of 1 km2 on our planet.

May and June

We successfully run the 4th edition of the EODA (Earth Observation Data Analysis) Lab in the frame of the ESA Research and Service Support. Through the EODA Lab we opened a window on the sensors, characteristics, and main applications of the Copernicus Sentinel 1-2-3 missions to aspiring data scientists attending the EODA course taught by prof. Marzano within the Master Degree in Data Science of Sapienza University of Rome.

Alongside our activities in the education field, the work we performed in the two following projects has been featured in two new publications.

Part of the work carried out in the frame of the ESA funded project AIDEO (AI and EO Data Innovative Methods for Monitoring West Nile Disease Spread in Italy) together with IZSAM, Istituto Zooprofilattico Sperimentale dell’Abruzzo e del Molise “Giuseppe Caporale, AImage Lab (University of Modena and Reggio Emilia) and ReMedia resulted in a research paper titled [Vincenzi, S., et al. 2020] “The color out of space: learning self-supervised representations for Earth Observation imagery” accepted at the 25th International Conference on PATTERN RECOGNITION (ICPR 2020). The publication provided new insights into the development of effective deep learning techniques for Remote Sensing, proposing for the first time a novel representation learning procedure on a colorization-based method which allows users to overcome the lack of large annotated datasets for satellite images.

The second one [Cigna, F., et al. 2020] “Supporting Recovery After 2016 Hurricane Matthew In Haiti With Big Sar Data Processing In The Geohazards Exploitation Platform (GEP)”, features a work led by the Italian Space Agency aimed at investigating the generation of experimental scientific products of change detection and ground deformation monitoring that Haitian end-users can exploit to support decision-making process and recovery progress after the Hurricane that hit Haiti back in 2016. More specifically, the project exploited two processing services available in the ESA’s Geohazards Exploitation Platform (GEP) that were integrated by us in the context of the RSS service support provisioning.

At the same time the RSS team collaborated with La Sapienza University of Rome in the research project SMIVIA – Snow-mantle Modeling, Inversion and Validation using multi-frequency multimission InSAR in central Apennine addressing snow-deposits monitoring using multi-frequency multi-mission InSAR in central Apennine, by supporting the research team with the automation of the InSAR processing chain and with elaborations and expert technical assistance for the use of the RSS CloudToolbox service.

July and August

The first of August marked an important milestone for the ESA Research and Service Support service which entered into an extension phase until Summer 2021. The tasks we have been in charge so far will remain unchanged during this extension phase. We will continue to be responsible for the service operation and for providing research support by facilitating Earth Observation data exploitation, the development of new algorithms and the generations of value-added processing results.

In these months, we also laid important groundwork for three new Earth Observation tools which we plan to deliver as operational services in 2021:

  • Integration of ACOLITE (Atmospheric Correction for Operational Land Imager) in the processing environment, allowing for a simple and fast processing of coastal and inland water applications;
  • Development of CoDeMinT (Coastline Detection and Monitoring Tool) extracting and analysing shorelines from Landsat and Sentinel-2 imagery;
  • the Cloudy Earth Observation Time Series Restoration Tool, a working implementation of the algorithm proposed in [Bertoluzza et al. 2019] to restore the missing pixels of multispectral imagery time series acquisitions covered by clouds.

September and October

Our team participated in the digital edition of the ESA EO Phi-Week, the ESA event dedicated to the latest achievements in Earth Observation science, technology and applications. We showcased the tools, services and projects derived from some of our latest research and engineering activities:

In the same period, the ESA/ESRIN contract “Maintenance and Evolution of the Copernicus Apps for Mobile Devices” was successfully completed. The contract, started in 2017, has rebranded and upgraded the Copernicus Sentinel App which became one of the most successful ESA mobile apps as of today, with 16 different app versions delivered over the years. In parallel to the evolution of the Copernicus Sentinel App, two new prototypes were also developed within the contract: the Copernicus Eye and the Copernicus Dashboard. The former visualizes information on land, atmospheric and ocean variables taken by The Copernicus Services. The latter is a web-base version of Copernicus Sentinel App. We played an important role as Customer’s interface and in the software independent testing and validation activities to ensure a proper functioning of the apps. The maintenance of the current features of the Copernicus Sentinel App is guaranteed, therefore it is still possible to download the most recent app release on the App Store and Google Play. Its newest features allow users to track the different Copernicus Sentinels directly from their ground position, browse new products for Sentinel-3 and Sentinel-5P through the search feature and download the different Sentinel products on the computer with the Sentinel Download Manager.

November and December

The results of our collaboration with IZSAM, AImage Lab and ReMedia within the AIDEO Project were presented in a final review meeting with ESA. Combining past West Nile Virus occurrences, Earth Observation data and Machine Learning algorithms, the project aimed at putting in place a model to predict areas at risk of West Nile Disease circulation two weeks in advance.
The results were promising and represented an important first step towards the development of an early warning system that could support public authorities in better targeting surveillance measures for the prevention of West Nile Disease. Our contribution was focused on the generation and provisioning of Analysis-Ready-Data tailored to the artificial intelligence requirements, which considerably facilitated EO data exploitation and value-added information retrieval.
A conclusive AIDEO paper [Candeloro, L., et al. 2020] “Predicting WNV Circulation in Italy Using Earth Observation Data and Extreme Gradient Boosting Model” was also published in the MDPI Remote Sensing journal and is available here.

In the same months, the first phase of the validation activities for the new S3 SLSTR FRP nighttime product has been successfully concluded in collaboration with the S3 SLSTR Mission Performance Centre experts, and its results have been included in an interactive Web Application. The project officially entered its second phase: the development of the daytime algorithm is currently ongoing, the validation algorithm is being revised and updated accordingly, and the web application is being upgraded.

In the meantime, the RSS altrimetry processing services offer continued to expand improving accuracy and spatial resolution. The SARvatore service in G-POD now offers the possibility to include in output an additional product obtained with ALES+ SAR retracker, a waveform retracker for open ocean and coastal zone SAR altimetry data. The family of SARvatore services was enriched with a Fully Focused SAR altimetry algorithm for CryoSat-2 (FFSAR, developed by Aresys), which allows for a consistent improvement of the along-track spatial resolution (from about 300 m to order of meters), and the Sentinel-6 High Resolution L1A Ground Processor Prototype (GPP) processor.

Over the last year the entire Progressive Systems team joined forces to bring to light a new platform for the analysis of Earth Observation Data which will be released in 2021 and that will incorporate some of the tools and competencies we have developed in 2020. This is Earth Console, a platform bringing Earth Observation data, algorithm development, integration and processing services, analysis and visualization tools, powerful computing resources and high-speed network connections, all in one place. A comprehensive service characterized by a great degree of flexibility allowing its users to exploit satellite data at diverse extent depending on their needs, from developing their own algorithm, to accessing specific know-how to scale up their application to massive data processing or wide service exposure.

Stay tuned and we really look forward to an even more fruitful 2021!

The “Maintenance and Evolution of the Copernicus Apps for Mobile Devices” contract successfully completed

/in /by

The Consortium which developed one the most downloaded ESA mobile apps shared project results in a final presentation

Funded by the EU and ESA

During a final presentation held online on the 10th of November, the Consortium led by Solenix and composed by Progressive Systems, Qualteh JR, Terrasigna and GISAT presented the results achieved over the last three years in the frame of the ESA/ESRIN contract “Maintenance and Evolution of the Copernicus Apps for Mobile Devices”. The project kicked off back in 2017, has rebranded and upgraded the Copernicus Sentinel App which enables users to track the Copernicus Sentinels satellites in real-time, discover their key elements, read the latest news and learn more about their products. Downloaded and installed on more than 56k devices, the Copernicus Sentinel App is one of the most successful ESA mobile apps as of today. Such a success is given by the fact that the Consortium delivered 16 different versions of the App over the years including newer functionalities which were able to increasingly meet the needs of both a specialized and general audience. As a proof of this transversal interest, the Copernicus Office used the App for diverse promotional and educational purposes. At the same time, its features would also allow more expert users to download Sentinel data on one’s device and trigger a processing of the products from the App.

The latest update of the app released on the 29th of October is available free of charge on the Apple store and Google Play and allows users to:

  • Track the different Copernicus Sentinels directly from your position and with your phone;
Tracking from Ground
  • Browse new products for Sentinel-3 and Sentinel-5P through the search feature;
Sentinel-3 products
Sentinel-5P products
  • Download the different Sentinel products directly on the computer (Windows or Mac). Users just need to install the Sentinel Download manager on their computer and select which data want to download from the App. The software and all the instructions to set up the Download Manager are available here;

In parallel to the evolution of the Copernicus Sentinel App, two new prototypes were also developed: The Copernicus Eye and the Copernicus Dashboard. The former represents a more modern version of My Vegetation App, the app dedicated to promoting the ESA PROBA-V mission providing information on vegetation as seen from space. The Copernicus Eye extends its functionalities to variables other than the vegetation ones such as land, atmospheric and ocean information provided by the Copernicus Services. The latter includes features similar to the Copernicus Sentinel App’s ones but on a web-based solution, readily available from a browser and targeting ESA internal users.

Given its experience and knowledge of ESRIN, in this frame Progressive Systems played an important role as Customer’s interface, collecting requirements and specifications emerging from ESA end users’ needs to be included in future developments of the apps. The company was also in charge of the software independent testing and validation according to defined guidelines to ensure a proper functioning of the apps.

While the maintenance of the current features of the Copernicus Sentinel App will be guaranteed over the coming period under a new contract with ESOC, the successful outcomes of the project may open up promising horizons for new developments to be explored in the future.

New Copernicus Sentinel App release takes users into deeper discovery journey through Sentinel missions

/in /by

The Solenix-led Consortium rolled out an update bringing a new set of features to the App



Funded by the EU and ESA

Available from the 1st of April, the new version of the Copernicus Sentinel App comes with a brand-new set of features offering an upgraded experience to those who want to have an overview on the Copernicus Sentinels, the EU’s constellation of satellites specifically dedicated to the operational needs of the Copernicus Programme, the Earth Observation programme headed by the European Commission (EC) in partnership with the European Space Agency (ESA).

The new release introduces products for S-5P, a precursor satellite mission performing atmospheric monitoring. Just like for other satellites, users can:

  • track the sentinel satellite in real time, move the sentinel along its orbit, display future acquisitions and visualize when the satellite downloads the data to the Ground Station;
  • search for and browse products in a specific point over the 3D globe, visualize the latest product acquired from the satellite and get a notification when a new product is available;
  • visualize case studies on what the mission has achieved so far for the benefit of society;
  • interact with the sentinel 3D model and its main components;
  • read latest news, watch videos and visualize statistical info about the products.
Acquisition of products feature over a specific area of the 3D globe.

In addition to this, with the more user-friendly ‘Map Layers’ menu option users can now also easily manage the visualization of the layers over the 3D globe and optionally display the atmosphere and day/night effect, the elevation model, the name of places and the constellations.
