Geohazards Community Online Questionnaire

This link brings you directly to the Community Survey online questionnaire

Today we are opening an online survey to involve more parties from research, industry, administration and government authorities in the evolution of the Geohazards Thematic Exploitation Platform (GEP) services.

GEP is an R&D activity developing a new ground segment operations approach, complementary to the traditional operations concept, and demonstrating the benefit of new technologies for large scale processing of EO data. 

The platform is intended to support initially the global geohazards community’s objectives, as defined in the context of the International Forum on Satellite EO and Geohazards, organised by ESA and GEO in Santorini in 2012. In particular, GEP is a follow-on to the SuperSites Exploitation Platform (SSEP), an ESA initiative to support the Geohazards Supersites & Natural Laboratories initiative (GSNL) of the Group on Earth Observations (GEO).

GEP allows both on-demand processing for specific user needs and systematic processing to address common information needs of the geohazards community as a whole, as well as massive processing on multi-tenant computing resources on the Cloud. Such capacities will address the challenges of monitoring tectonic areas on a global basis, and of studying a range of geohazards. To exploit the geo-information generated using the Platform, GEP leverages open APIs for the integration of interactive processing and post-processing services.

The Platform follows a model for partnership and community building that is user driven. Fundamentally the current solution has been designed from working on user requirements from the GEO initiative on Geohazards Supersites and the CEOS Working Group on Disasters, with its Seismic Pilot involving a range of expert users such as for example the University of Leeds for UK’s COMET, ISTerre for the french Formater network, the italian Istituto Nazionale Geofisica & Vulcanologia, UNVACO, or NASA/JPL and University of Miami in the USA.

The evolution of the current platform into an operational service is following a capacity building process driving the requirements, design and implementation activities. This process includes a mechanism to gather user needs in liaison with the following types of organisation: 

  • Geo-science community incl. Universities (PIs) worldwide;
  • Organisations with a national mandate concerning risk assessment (incl. seismological centres);
  • Specialists of geohazard risks in other sectors (pre-commercial research affecting insurance/reinsurance sector, civil engineering companies, energy, etc.);
  • National & regional civil protection agencies and national & local authorities with a risk management mandate (potentially for both prevention/preparedness and response).

This process allows the GEP consortium to design functionalities able to meet prioritized user needs in view of efficient and cost effective operations. 

The programme of work covering the period 2016­-2017 will pursue activities with the Platform’s early adopters and will evolve the 16 processing applications currently available to exploit conventional and advanced InSAR processing for precise motion monitoring. The activity will develop six Pilot projects to demonstrate the potential of federated processing of EO data on the Cloud: a new pilot on photogrammetric processing using optical EO data with Univ. Strasbourg (France), the integration of optical based processing method for volcanic hazard monitoring with INGV (Italy), a pilot on terrain motion surveillance with CNR-­IREA (Italy), the systematic processing of Sentinel­-1 interferometric quick looks with DLR (Germany), the integration of a PSinSAR chain for precise terrain motion mapping with Altamira Information (Spain) and an exercise with the Corinth Rift Laboratory to test and exploit the platform processors and services to support geohazards science in this seismic part of Greece. In this course, the GEP will expand its overall user base to gradually reach a total of 60+ registered user applications in 2017.

This growing user community is a key aspect for the GEP consortium so we have created an online questionnaire to involve more parties from research, industry, administration and government authorities in the evolution of the platform’s services.

You have now the opportunity to contribute your needs and expectations in terms of functionality enhancements, use scenarios, services portfolio, data provisioning and concrete benefits for the GEP users.

The online survey is structured in 5 parts, and on average, it will take only 10 minutes to complete:

  1. About you
  2. Your thematic interests and current practices
  3. You as a geohazards platform user
  4. Your objectives with EO data [ incl. a branch for SAR experts ]
  5. Finally, your vision of a research community platform

You can access the survey by following this link:

Report of the User Consultation on Disaster Risk Reduction (DRR) & new satellite EO methods

On 27th November 2015 ESA hosted a User Consultation on Disaster Risk Reduction using new satellite EO methods jointly organised by e-GEOS and ALTAMIRA INFORMATION in the framework of the General Studies Programme (GSP) led by the European Space Agency. These studies are looking at new Earth Observation (EO) methods & new ICT technologies to improve the understanding and management of natural hazards.

The primary objectives of the event were to better understand geo-information requirements about Disaster Risk Reduction, share ideas about new methods and new underlying technologies to exploit satellite EO for hazard and risk mapping and identify issues for which innovative techniques could be tried in the themes: landslides, earthquakes, flooding & volcanoes.

A total number of more than 40 participants belonging to more than 20 different public or private organizations from 10 different countries and staff from international organisations such as the United Nations joined the event and actively contributed to the working sessions.

New hazard mapping to demonstrate the contribution of satellite data to DRM in Bhutan and Nepal.

ESA has originated a pilot project in the framework of eoworld2, a collaboration between the European Space Agency and the World Bank, to demonstrate the benefit of satellite EO to support Disaster Risk Reduction (DRR) in Nepal and Bhutan.

The Hindu Kush Himalayan Mountains are the source of 10 major river systems and provide vital ecosystem goods and services to more than 1.4 billion people spanning a range of countries from Afghanistan, Bangladesh, Bhutan, China, India, Myanmar, Nepal to Pakistan.

The World Bank has numerous on-going projects in the Himalayan mountain region, ranging from agriculture, rural roads, climate change, watershed management. In Nepal and Bhutan it is actively involved since several years in projects related to hydroelectricity and infrastructure planning (roads, dams, agriculture) and makes use of existing national data provided by the involved agencies from both countries.

The pilot is conducted by a Swiss team comprising of MFB-GeoConsulting GmbH, Gamma Remote Sensing AG and SUPSI-IST. Project users include World Bank staff and local users involved with risk management and sustainable development.

Welcome to the Urban TEP

The main goal of the Urban Thematic Exploitation Platform (TEP) is the implementation of an instrument that helps addressing key research questions and societal challenges arising from the phenomenon of global urbanization.

Therefore, the Urban TEP represents a web-based platform that allows users to effectively utilize Earth Observation (EO) imagery and existing auxiliary data (e.g., geo-data, statistics) to measure and assess key properties of the urban environment and monitor the past and future spatiotemporal development of settlements.

Key elements of the Urban TEP are the provision of easy and high performance access to EO data streams and archived data, multi-mission and multi-source data management and processing infrastructures, modular pre-processing and analysis procedures (value-adding processors), user-oriented functionalities for product and service development, validation and standardization as well as exchange and distribution of ideas, methods and thematic layers.

To maximize the relevance and societal benefit of the Urban TEP, the initiative includes a comprehensive concept for active expert knowledge and user community integration. Hence, the Urban TEP core consortium – consisting of 5 partners - is supported by a network 6 key user communities including the group of scientists conducting the Group on Earth Observation (GEO - Task SB-04 Global Urban Observation and Information), the World Bank Group, the European Environment Agency (EEA), DG Regio of the European Commission, the International Society of City and Regional Planners (ISOCARP) and the City of Prague. In addition, 7 associated consultancy partners will bring in their expertise and competences in key sectors relevant for the Urban TEP development, implementation and sustainability.

Accessing Sentinel-1 Orbit files on Geohazards TEP

Several ESA Geohazards Exploitation Platform (GEP) early adopters applying for the scenario 2 ‘New EO Service Development’ are currently supported for the integration of their data processing chain on the GEP Cloud environment. 

The resulting processor integration is then made available from the GEP Portal to users (upon sign-in credentials for https://geohazards-tep.eo.esa.int/). On the Portal, authenticated users can select data over an area of interest, set processing parameters, run a processing job and share their results on the platform.

To support these processor integration activities, we have defined an application template, dedicated to the access and the processing of Sentinel-1 data from the Platform. The template, together with the installation procedure, is available on GitHub

Based on this application template, under src/main/app-resources/myapp/run, developers of new Processing applications can now retrieve from the Platform’s catalogue the Sentinel-1 products together with the Precise Orbit Ephemerides data (or POD).

From a running workflow, a function is typically getting the start/end time of the current Sentinel-1 product to be processed, and an OpenSearch query is then performing the retrieval (using the “enclosure” parameter, that provides with the file download location) of the corresponding PODs. A last step is downloading the orbital data from the enclosure reference, and storing it on the proper file system location, in order to be ingested by the SAR processing code embedded in the new application.

In average, ESA releases the Sentinel-1 POD Precise Orbit Ephemerides 20 days after the related acquisition. If you want to process Sentinel-1 products acquired in near-real time, you can also use the orbital data enclosed within the Sentinel-1 product.

2D displacements over Nepal

2D displacements over Nepal using Sentinel-1 pixel correlation

The Remote Sensing Technology Institute of DLR has published measurements derived from pixel correlation providing 2D displacements following the 25 April 2015 earthquake.

Sentinel-1 data allowed to measure a negative range shift of about 0.8 meters, corresponding to a possible uplift of about 1 meter and an azimuth shift on the order of 1.8 meters.

This is an absolute measurement derived from Sentinel-1 orbital geometry without any reference point on ground.

Welcome to the Hydrology TEP!

The main challenge of the Hydrology Thematic Exploitation Platform (TEP) is offering an ensemble of services to the Hydrology community based mainly on the exploitation of different EO data and tools. The goal of these services is facilitating the access, exploitation, processing and visualization of different type of data (EO, in-situ, socioeconomic or meteorological data) to the end-users in the different applications related to water management such as water resource management, floods monitoring, drought monitoring or water quality monitoring.

As water touches all societal and environmental domains, from the pint of view of end-users, there is a need for integrated, open water information services offering efficient access to cross-regional, multidisciplinary water information for all types of end-users, such as governments, scientists, businesses and civil society. The needs are particularly high in the developing world which is often data sparse. By exploiting the untapped potential of new IT cloud environment, new plethora of data of Sentinels and Third Party Missions data and new SaaS customized to the hydrology community needs, water-related challenges can be better mastered by a combination of holistic understanding of the water cycle together with evidence- based governance and increased public awareness.

In this process, EO data could play in particular a much more significant role if properly included in existing and new decision support tools for water managers and policy makers.
