Planetek Hellas, acting as the prime in the submitting company grouping, together with Planetek Italia, CMCC, KSAT and Creotech Instruments, has been awarded the MARINE-EO PCP Phase 2 project for the design, development, testing and demonstration of the Lot 1, titled: SATOCEAN - Copernicus Marine Environment Monitoring and Climate Change.

The consortium led by Planetek Hellas started the Phase 1 of the PCP (Design) on July 2018 and in October 2018 was evaluated with the highest ranking, among the three consortiums that continued in Phase 2 (Prototype).

MARINE–EO is “the first Earth observation pre-commercial procurement in Europe, cofounded by the H2020 program” aiming at procuring the development of demand-driven EO-based services, adopted on open standards, bringing incremental or radical innovations in the field of maritime awareness and leveraging on the existing Copernicus Services and other products from the Copernicus portfolio. (https://marine-eo.eu)

The Marine Environment Monitoring is a complex cross cutting area where Earth Observation (EO) satellites and more specifically, Copernicus Sentinel’s provide major contribution. This complexity and diverse topics that need to be monitored and explored can be summarized in the following three use cases:

1. Marine Environmental Status in Hot Spots;

2. Fish Farms: Detection of Fish Farm Threats;

3. Detection of Vessels and Icebergs in the Arctic zone.

The three use cases are the integral part of the SATOCEAN (Lot 1) activity developed by Planetek Hellas consortium and will be designed and realized by exploiting the competences and expertise of the consortium to provide the services, Planetek for the WQ and aquaculture services (Rheticus Marine) and KSAT for the vessels and iceberg identification and routes. All the services will be implemented through a complex and advanced system based on Creotech’s Data and Information Access Services (DIAS) platform.

The first two use cases refer to the monitoring hot spots in coastal marine environment. The third use case refers to the maritime safety with regards to ice shipping route, vessel detection and iceberg monitoring.

Coastal and Marine Environment contributes to water quality monitoring and to environmental risk assessment. Specifically, Copernicus Marine Environment Monitoring Service (CMEMS) provides long time-series of in-situ (physical and biochemical) and remote sensing (ocean colour and SST) products and data that feed coastal areas with important information. This information is vital for monitoring the status of coastal areas, adhering to the Marine Strategy Framework Directive (MSFD), and other related products. Using CMEMS data, Copernicus Sentinel imagery, available in-situ measurements and specialized hydro-physical models, the consortium will:

  • Provide a wide set of EO based products from Copernicus under free and open license and data obtained from other freely available satellite missions in order to obtain relevant parameters on the quality of sea areas of interest. In this context, the use of advanced modelling will improve spatial resolution reaching values less than 1km x 1km. (First and second case histories)
  • Provide innovative monitoring information and routing services to support involved authorities as well as ships navigators on board the ship and private industries in their activities of monitoring, navigation in or near ice and ice defence in the Arctic zone. (Third case history)
  • Develop innovative interfaces aiming in making easy and immediate the access to the relevant information to the different users communities interested by the information services provided. (all case histories)

TerraScan examines raw material deposits such as Lithium- and Kobalt for strategic analyses of offer and demand for the E-mobility Industry and next generation car battery developments. TerraScan applies its proprietary gScan Technology, a satellite pictures based analytic tool for global raw material sourcing. TerraScan's approach enables rapid, environmentally friendly and discrete exploration of new and existing deposits around the world without prior licensing in the context of geological exploration.

TerraScan could convince Volkswagen as one of the first industrial customers about its innovative technology. Volkswagen recognises the opportunity to localise quickly relevant raw material deposits such as Lithium and Kobald for e-mobility as a chance to secure its raw material demand in the long term.

The first exploration took place by processing very big territories down to 500 meters and beyond within a timeframe of only a few weeks. Details are not going to get disclosed.

The goal for Volkswagen is to secure the covering of its demand from sustainable sources at longterm projectable conditions. Volkswagen is therefore in close contact with all partners along its value chain. The analyses of barely tapped deposits is for Volkswagen an innovative addition to their current strategic activities.

"This project demonstrates our ability to provide investors and strategic decision makers with detailed knowledge, options and decision support for securing raw material sources quickly and early in the decision-making process, without having to undertake extensive on-site investigations." Jörg Enge, Managing Director and Founder, TerraScan GmbH.

TerraScan GmbH is a Berlin-based NewSpace service company that specializes in the efficient and sustainable discovery of mineral resources. The proprietary gScan process uses satellite images applying geological expertise, specially developed algorithms and artificial intelligence to identify all types of natural resources. It has been successfully applied to oil, gas, water, lithium, precious metals, and even water and geothermal energy sources. Detailed data is generated on location, depth, distribution and quantity both at sea and on land, even in the mountains. By nature, gScan is much faster and cheaper than conventional methods. In contrast to seismic, blast testing or drilling previously used, gScan is non-invasive, totally discreet and sustainable. It is also highly efficient to scan entire regions or countries for target resources.

ZUR SOFORTIGEN VERÖFFENTLICHUNG/ FOR IMMEDIATE RELEASE

Volkswagen nutzt Terra Scan zur Sicherung von Lithium und Kobalt

TerraScan untersucht Rohstoffvorkommen wie Lithium- und Kobalt für die strategische Angebots- und Nachfrage Analyse der E-Mobility Industrie für die Entwicklung der nächsten Generation von Autobatterien. Dafür nutzt TerraScan seine gScan Technologie zur Satellitenbilder gestützten Analyse weltweiter Rohstoff Beschaffung. TerraScan’s Ansatz ermöglicht die umweltfreundliche Untersuchung von neuen und bestehenden, globalen Lagerstätten ohne vorherige aufwendige Lizenzierungsprozesse im Rahmen einer geologischen Exploration.

Als einen der ersten Kunden konnte TerraScan Volkswagen von seiner innovativen Technologie überzeugen. Die Möglichkeit schnell relevante Rohstoffvorkommen wie Lithium und Kobalt für die E- Mobilität zu lokalisieren ist eine Chance für Volkswagen, seinen Rohstoffbedarf langfristig abzusichern.

Die erste Untersuchung erfolgte durch Verarbeitung sehr großer Territorien bis zu einer Tiefe von mehr als 500 Metern in einem Zeitfenster von wenigen Wochen. Details werden nicht veröffentlicht.

Volkswagens Ziel ist die sichere Deckung ihres Bedarfes aus nachhaltigen Quellen und zu langfristig planbaren Konditionen. Zu diesem Zweck steht Volkswagen im engen Austausch mit allen Partnern entlang ihrer Wertschöpfungsketten. Die Analyse bisher nicht erschlossener Vorkommen stellt für Volkswagen eine innovative Ergänzung ihrer aktuellen strategischen Aktivitäten dar.

„Dieses Projekt ist stellvertretend für unsere Fähigkeit, Investoren und strategischen Entscheidern Detailkenntnisse, Optionen und Entscheidungsgrundlagen für die Sicherung von Rohstoffquellen innerhalb nützlicher Frist und sehr früh in der Entscheidungsfindung zu beschaffen, ohne sogleich aufwendige Untersuchungen vor Ort durchführen zu müssen.“ Jörg Enge, Geschäftsführer und Gründer, TerraScan GmbH.

TerraScan GmbH ist ein Berliner New Space Dienstleistungs Unternehmen, das sich auf das effiziente und nachhaltige Auffinden von Bodenschätzen spezialisiert hat und verfügt über eine weltweit führende Technologie: Das proprietäre gScan-Verfahren identifiziert auf Grundlage von Satelliten- Bildern unter Verwendung von geologischem Fachwissen, speziell entwickelter Algorithmen und künstlicher Intelligenz Bodenschätze jeder Art. Es wurde bereits erfolgreich angewendet auf Öl, Gas, Wasser, Lithium, Edelmetalle uvm., sogar Wasser und Geo-Thermie. Es werden detaillierte Daten erzeugt über Ort, Tiefe, Verteilung und Menge sowohl auf See als auch auf Land, sogar im Gebirge. gScan ist naturgemäß sehr viel schneller und kostengünstiger als die konventionellen Verfahren. Im Gegensatz zur früher verwendeten Seismik, Sprengversuchen oder Bohrungen ist gScan nicht-invasiv, völlig diskret und nachhaltig. Auch ist es möglich hoch-effizient ganze Regionen oder Länder nach Bodenschätzen zu scannen.

Auf www.terra-scan.com gibt es einen guten Überblick und einige Fallstudien unter https://terra- scan.de/projects.

Queensland State shows how images from space can support and improve decision-making for Governments and agencies. 30 January 2019 – New Space pioneer Earth-i today announced that it has completed the third annual update of the satellite map of the state of Queensland.
The map covers the whole of Queensland’s 1.9 million km2 and was created by Earth-i for the Department of Natural Resources, Mines and Energy (DNRME). The first map was produced in 2016 with Earth-i reappointed for updates in both 2017 and 2018.

Around 6,000 very high-resolution images from the DMC3 Constellation were used for the 2018 update of the map with multiple re-visits to tropical areas with heavy cloud cover.

The images have a pixel size of 80cm (one pixel equates to 80cm on the ground) so that details such as individual trees can be easily seen.

All three maps are available on an online portal – ‘The Queensland Globe’ where images can be viewed and printed.

These images are used by a variety of Government departments, local agencies and natural resource management groups to manage and monitor Queensland’s resources and improve policy development, investment and planning decisions. The map also helps to monitor environmental changes, and helps with the planning of long-term land development strategies.

Earth-i faced strong competition to lead this prestigious project which has set the standard for Governments across the world who are looking to use images of Earth taken from space to improve their decision-making.

Steve Jacoby, Executive Director of Land and Spatial Information at the Queensland Department of Natural Resources, Mines and Energy, said “Earth-i is an innovative company that combines quality images and analysis with excellent service. The Queensland Globe is very well used and helping to improve the decision making of a wide variety of organisations.”

Paul Majmader, Commercial Director of Earth-i, said “Winning this contract for the third consecutive time is a tribute to our entire team. The DNRME in Queensland is showing Governments around the world how important regularly updated, high resolution data is in making informed policy decisions.”

As qualified suppliers to other states in Australia, Earth-i is helping Australia retain its position as a leader in the development of geospatial data infrastructure which is driving both economic development and good environmental management.

About Earth-i

Earth-i currently provides satellite imagery, data analysis and insights services from a range of Earth Observation (EO) satellites, including the DMC3, SuperView, KOMPSAT and Planet constellations of satellites. Earth-i launched its own satellite service demonstrator satellite, VividX2, in January 2018.

The company is pioneering the application of machine learning and AI solutions to Earth Observation data to provide deeper insights in support of critical business decisions and policy formulation. Earth-i has a wide range of clients globally including National and Local Governments and a multitude of specialist geospatial companies and other commercial organisations.

The upcoming launch of its own satellite constellation, Vivid-i, is a natural evolution of Earth-i’s existing and well-regarded image and EO analytics business. The Vivid-i Constellation will enable Earth-i to meet the rapidly growing demand for high-resolution EO data, analytics and insights, whilst delivering pioneering high-frame rates, ultra-high-definition colour video, and very high frequency revisits.

As recently as in 2013, it was estimated that at the end of last year, the value of the global market of cloud will reach the level of 32.5 billion dollars. Meanwhile, it is almost 5 times higher.

Almost every fourth company in the European Union uses the cloud

The latest Eurostat research shows that in the last 4 years the use of cloud computing among large companies in the European Union has increased by over 20%. Currently, 26% of enterprises use cloud computing. It is worth noting that statistically the larger the company, the more often it uses cloud computing.

This is confirmed by numbers – the largest percentage of cloud use (56%) is found among the largest companies that theoretically have their own resources, and yet more often decide to outsource. The public administration also increasingly places on the cloud.

‘A simple profit and loss account wins. Cloud will always be a cheaper solution than maintaining infrastructure on its own, in addition, the administration collides today with the problem of a shortage of specialists who prefer to work in enterprises. It is also worth paying attention to the trend of investing in the cloud of the foreign public sector’ – notes Urszula Mielcarz from CloudFerro, a company that, on behalf of the European Space Agency, stores data from the Copernicus satellites in the cloud.

Geographical differences

According to research, there are significant differences between individual countries in the use of cloud computing in the EU. While in Poland the percentage of companies using the cloud in 2018 reached only 11.5%, in Finland, Sweden and Denmark – 65.3%, 57.2% and 55.6% respectively.

In the ranking of countries most willing to use cloud solutions, Poland is on the third place from the end, before Bulgaria and Romania. No wonder – in the years 2014-2016, the percentage of Polish companies using the cloud grew by 1% per annum. For comparison, e.g in Finland, annual increases in the same period ranged from 51 to 57%.

‘The use of cloud computing strongly correlates with the digital advancement of individual European Union countries. In countries that have been investing in fiber-optic links and digital competence of citizens for years, the use of cloud computing is the most common’ – comments Eurostat data Urszula Mielcarz from CloudFerro.

It gets better and better for the cloud market

It turns out that the predictions about the cloud computing market from just a decade do not only meet, but were too timid. In 2010, the American research company Pew Research Center conducted a survey among current and potential cloud users, asking them about the forecasts related to its use in the future. As many as 71% of respondents indicated the answer “in 2020, the norm will be functioning in the cloud, and the work will be done mainly with the use of applications in cyberspace, available through network devices”. It is safe to say that they had a good feeling.

It is worth adding, however, that the forecasts for the value of the cloud computing market from the beginning of this decade were heavily underestimated. At the beginning of 2013, the analytical firm IDC (International Data Corporation) estimated that the cloud market at the end of 2013 will reach the value of 8.6 billion dollars, and for the next 5 years will increase by a cumulative rate of 24.8%. It is easy to calculate that according to this forecast, the value of the cloud market in 2018 was to amount to 32.5 billion dollars. Meanwhile, in reality it was … more than 5 times more.

Steady increase

Goldman Sachs research indicates that the company’s spending on the cloud, which currently accounts for 8% of IT budgets, will rise to 15% by 2021. So the increase will be very significant. The analyst Dave Bartoletti from Forrester also talks about the increased dynamics of the global cloud computing market – More and more commonly the implementation of cloud computing will drive digital transformation.

The global market for data processing in the cloud has a chance to exceed USD 200 billion in 2019. It would be a 20% increase compared to the previous year.

This is the same as the growth in EU companies, but within four years. In addition, Gartner predicts that in 2025 as many as 80% of enterprises will already be operating in the cloud.

According to Gartner’s analysts, in 2021 the Polish cloud computing market could approach $ 300 million. However, as the history of this type of analysis shows, after years it may turn out that they were too cautious, and the IT market driven by the development of technology can surpass even the best forecasts.

January 2019 – What is a coverage, after all? This fundamental spatio-temporal data structure, encompassing (among others) datacubes, is widely used, based on adopted and implemented OGC and ISO standards like WCS. However, the conceptual foundations are outdated. This is being changed now.

On a high level it is clear: ISO 19123, which is identical to OGC Abstract Topic 6, describes the foundations of coverages. Accordingly, coverages encompass regular and irregular spatio-temporal grids, point clouds, and general meshes. However, this standard – crafted around the year 2000 – is not up-to date and needs urgent revision according to ISO and other experts. Definitions like “a raster is like a grid of pixels on a cathode ray tube” are not exactly representing modern understanding.

Therefore, ISO since several years has set up a New Work Item Proposal (NWIP) based on which project leader Prof. Liping Di at the US George Mason University in the US is looking for a writer of the specification. Peter Baumann, rasdaman CEO, was approached, but could not do it earlier due to urgent work on other standards. In 2018, an agreement was finally reached with DIN, the German standardization body, to establish a national project led by Peter Baumann to establish a new abstract coverage specification.

ISO has decided to split the coverage standard into a pair of companion standards, 19123-1 (abstract foundations of coverages) and 19123-2 (concrete, interoperable coverage definition which allows mapping to a variety of data format encodings). The latter, 19123-2, has been adopted by ISO in 2018 from the corresponding OGC Coverage Implementation Schema (CIS) in an ISO project led by Peter Baumann. For the former, 19123-1, the so-called DIN-CONNECT project has submitted a complete specification by the end of the year, fully according to plan. This coverage specification will now become German national standard and simultaneously will be submitted to ISO TC211 as German input to the project.

“It is extremely important to have a coherent set of standards”, says Peter Baumann. “We have put utmost emphasis on establishing a specification that is state of the art, open for the future, and yet compatible with the existing coverage standards ecosystem”.

CybELE, short for Cyber Environmental Law Enforcement, was announced as the overall winner on the 4th December 2018 night at the Copernicus Masters Awards Ceremony in Marseille, France.

The competition awards outstanding ideas and applications using Earth observation data to tackle environmental challenges faced by society.

CybELE has been honoured twice within this year’s Copernicus Masters B2B and Overall Winner Awards. CybELE solution aims to use satellite data to empower experts, especially in the private sector (law firms and insurance), with the management of their legal environmental cases.

Indeed, environmental crime, such as illegal landfill and forestry crimes, is a growing problem worldwide and an expensive one as well. At a global scale, environmental crime increases by an average of 5-7 % annually. Following an increase of 26% in 2014, it is estimated that in 2016 alone, environmental crimes incurred a global cost of between $91 billion and $258 billion.

To solve this problem, CybELE provides quick access to environmental crime reports for law firms and insurance companies. Saving time and money usually spent on research, the reports constitute crucial evidence of infringement of environmental laws and assess the cost of environmental damage.

The reports are based on an analysis of satellite data notably from Sentinels-1, -2, -3 and -5. They are drafted in a comprehensive manner to constitute a crucial evidential basis in the frame of judicial proceedings like litigation or dispute settlement.

The service finally enables companies or their clients to alleviate time and money consuming research required to support their cases. The reports are also improving the legal predictability of environmental cases and strengthen the client’s environmental claims.
ESA’s Director of Earth Observation Programmes, Josef Aschbacher, said, “Copernicus is Europe’s route to the future and it is the most ambitious Earth observation programme ever conceived.

“CybELE demonstrates its potential by using data from all active Copernicus Sentinels to optimise the management of legal environmental cases.”

“With applications like this, it is clear that the Copernicus Masters drive innovative use of Earth observation data and make the Copernicus programme accessible to new user groups.”

Introduction and demonstration of SAR interferometry services for monitoring of transport infrastructure has been selected as the best project funded by the Technology Agency of the Czech Republic in the Governance category.

Capabilities of SAR interferometry (InSAR) were demonstrated to the Czech Road and Motorway Directorate on multiple highway bridges in the Czech Republic. Pilots have been conducted in the framework of applied research project funded by the BETA Programme of Public procurement in research, experimental development and innovation for the government and the pre-operational feasibility studies were funded by the Czech Road and Motorway Directorate.


Mr. Jan Kolomaznik, project manager of GISAT, takes the Best Czech Applied Research Project Award from Mr. Andrej Babis, the Czech Prime Minister (right), and Mr. Petr Konvalinka, the Chairperson of the Technology Agency of the Czech Republic (left).

Interferometric deformation model considered complex construction behaviour assuming both linear displacements and cyclic thermal dilations as a result of temperature fluctuations. Various deformation behaviours were detected for different bridges and parts of their construction as a result of variability of bridge constructions, structural stability and orientation. The most notable deformations were detected especially in areas of bridge closures, which generally suffer from high subsidence rates resulting from compaction of subsoil material. These deformations affect adjoining parts of bridge construction and require regular monitoring followed by corrective measures (e.g. rectifications). Furthermore, it has been proved that both these subsidence and uplift deformations resulting from subsoil swelling can be also monitored indirectly by detecting displacements of supporting walls and noise barriers attached to the road body.


Cross-validation of InSAR results obtained by analysis of Sentinel-1 (left) and VHR SAR (right). D1-433 bridge, Czech Republic

Apart from demonstration cases comprehensive methodology for feasibility assessment of transport infrastructure InSAR based monitoring was prepared. In addition, suitable Artificial Corner Reflectors (ACRs) were designed, manufactured and installed as the attachment to bridge construction in compliance to requirements of the Directorate and applicable legal scope.

In the frame of this research project Gisat has introduced the methodology aiming at provision of common framework for selection of interferometric data and methods in support of subsidence and deformation risk monitoring within the transportation sector by means of persistent scatterers interferometry. Development of sustainable services based on InSAR approach shall provide temporally-rich information and cost-effective tools supporting early detection of potential risks and threads related to operation of transportation infrastructure in the Czech Republic.
