On 15 November 2017, there was a flood after heavy rainfall in western Attica, mainly affecting the areas of Mandra and Nea Peramos. The tragic account is that 24 people have died, and a lot of infrastructure and assets have been destroyed completely or partially.
The team of the FloodHub service of BEYOND was activated immediately after the incident and analysed it, both by using satellite remote sensing and photo interpretation, and by autopsies in the area (21-23/11/2017), for data collection and more detailed evaluation, including tracking the uncovered and covered parts of the watercourses but also their original natural flow, as well as the identification of critical points (66), the examination of the adequacy of the cross section of the watercourses and of the technical works, the shooting of photographs (287), and the formulation of relevant proposals on rehabilitation and prevention.

RAPID ASSESSMENT OF EARTHQUAKE DAMAGES AT VERY LARGE SCALE

From the recent earthquakes on the Greek island of Kefalonia, it became apparent that UAV technology can assist in mapping damages following a catastrophic event and assessing the Mercalli Intensity of the earthquake.

BEYOND, in collaboration with Geotech LTD (dealer of the Gatewing UAV in Greece) flew a mission over the urban area of Lixouri, five semi-urban areas (Vouni, Mantzavinata, Soullari, Agios Dimitrios and Livadi) and two rural areas (close to the road connecting Lixouri and Argostoli). Geotech LTD provided orthorectified images for each region. BEYOND team imported the images to a GIS and a point database was built in an attempt to detect and classify earthquake related damages. Three types of damages were monitored via simple ortho-interpretation: damages a) on ground level such as damages on roads, harbor infrastructure, cemeteries etc. and also small landslides, b) on walls and c) on roof-tops. This process was done via simple photo-interpretation.

FIRE AND DAMAGES MAPPING

Τhe “Department for the Recovery from the Impact of Natural Disasters” (Ministry of Infrastructure, Transport and Networks) assigned BEYOND “Centre of Excellence for EO-based monitoring of Natural Disasters” to undertake a pilot mission for the recording of damages caused by the fire in Thassos island on 10.09.2016. The mission included UAV flights to capture the affected areas and properties with high resolution digital photos and to deliver photo-interpreted orthomosaics of the areas.

EMS Activations

Copernicus EMS - Mapping provides all actors involved in the management of natural disasters, man-made emergency situations and humanitarian crises, with timely and accurate geospatial information derived from satellite remote sensing and completed by available in situ or open data sources. The information generated by the service can be used as supplied (e.g. as digital or printed map outputs). It may be further combined with other data sources (e.g. as digital feature sets in a geographic information system). In both cases it may support geospatial analysis and decision making processes of emergency managers. Copernicus EMS - Mapping is provided during all phases of the emergency management cycle, in two temporal modes, and free of charge for the users. It can be activated only by authorized users.

The infrastructure and excellence developed in the BEYOND Center of Excellence are actively involved in the provision of Risk & Recovery Mapping which consists of the on-demand provision of geospatial information in support of Emergency Management activities related to Emergency Support. This applies in particular to activities dealing with prevention, preparedness, disaster risk reduction and recovery phases. There are three broad product categories: Reference Maps, Pre-disaster Situation Maps and Post-disaster Situation Maps. The research developed in BEYOND, exploits satellite data and ingests fusions of geo-partial information and data in rush mode, when, where needed, for enhanced risk modelling and improved assessment of the expected disaster impacts.

The list of methodologies developed, adapted, validated, and used in BEYOND to address risk and recovery needs of the civil protection authorities worldwide are listed below (in more details in ANNEX III):

  • Seismic Methodologies: Seismic Hazard, Seismic Vulnerability, Seismic Vulnerability of Pipelines, Seismic Risk.
  • Lava Flow Methodologies: Lava Flow Hazard, Lava Flow Vulnerability, Lava Flow Risk.
  • Forest Fires Methodologies: Fire Damage Delineation & Burn Severity Grading, Damage/Biomass Loss Statistics, Forest Fire Hazard, Population & Assets Vulnerability to Forest Fires, Forest Fire Risk – Population, Assets and Transportation Network at risk.
  • Industrial Accidents Methodologies: Industrial Accidents Hazard, Industrial Accidents Exposure, Industrial Accidents Risk.
  • Tsunami Methodologies: Tsunami Hazard Assessment, Assets Vulnerability to Tsunami, Storm Surge Hazard Risk.
  • Soil Erosion Methodology: Soil Erosion Hazard.
  • Coastal Erosion Methodology: Coastal Erosion Vulnerability.
  • Ground Deformation Methodology: Ground Deformation Dynamics.
  • Landslides Methodology: Landslide Hazard, Landslide Vulnerability, Landslide Risk.
  • Subsidence and Landslide Methodology: Subsidence and Landslide Risk.
  • Floods Methodology: Flood Delineation at peak conditions, Flood Depth at peak conditions, Flood Damage Assessment, Flood Hazard, Flood Vulnerability, Flood Risk, Flash Flood Hazard triggered by earthquakes, Flash Flood Risk triggered by earthquakes.
  • Disruption of Transportation Networks Methodology: Vulnerability of Disruption of Transportation Networks.

Up to now the BEYOND Center has been activated in the framework of the COPERNICUS EMERGENCY MANAGEMENT SERVICE in the following worldwide disaster risk and recovery cases :
