Business Units Service Offering EMSR298/EMSV046 – S w e d e n Forest Fire Emergency EMSR298 Management • Exceptional large number of wildfires in the summer 2018. • The Copernicus EMS Rapid Mapping service was activated on the 16th of July 2018 by the Swedish Civil Contingencies Agency. • Fire delineation and grading maps were produced within 10 AOIs  39 QA maps.

EMSV046 • M1 field mission (2 AOIs): . Acquisition of Positional and Thematic Control Points. • M2 product technical validation: . Creation of a Burnt severity classes guideline. . Creation of reference data from field work data. . Reprocessing data based on post-event satellite images. . Assessment of the positional accuracy of the post-event images in the EMSR298 products. • M3 product evaluation: . An Authorised User and two End Users were interviewed. . The web GIS platform developed in ArcGIS Online (AGOL). D A T A SOURCES – METHODOLOGY Emergency 47 Activations Management Data sources: • Satellite imagery: optical and radar. • Field survey. • Aerial photographs: orthophoto, oblique, nadir. • Copernicus data: EFFIS, High resolution layers,… • UAV – Drones. • Alternative datasets: Pan-European, National, Local,… • DTM – DSM. • Crowdsourcing data: OSM, YouTube, Tomnod, Panoramio… • Videos. • Imagery platforms: Earth, Bing,… Methodology: • Photointerpretation: images, video, photographs. • Damage assessment over existing vector data sets. Reference data • Geoprocessing of vector/raster data.Analysis of non-geographic contents. • Automatic and semiautomatic extraction: images, radar, and vector datasets. Reprocessed data • Automatic image classification and segmentation based on Object Based Image Analysis • Damage coherence map creation. • MultiTemporal Coherence Comparable data • Interferometric Synthetic Aperture Radar (InSAR). • Vegetation Indices recalculation.

Emergency 1. Maturity of the Rapid mapping services: Methodologies, known limitations, standardization Management 2. Risk and recovery services implementation presents great opportunities and challenges. Data sharing and feasibility. 3. Communication channels importance. • Service providers – users: • ensure understanding of data limitations (oral communication, metadata, reports and marginalia), data status, methodology and service level required. • Service providers and validation service: recommendations implementation. 4. Ensure the common understanding of the grading classes (semantics). Fill the gap between the EO experts and the users perspective. (classification rules-marginalia or metadata) 5. Products: • Standardisation should be “flexible” enough. Number of categories adapted to the quality of the available imagery (spatial and spectral resolution) • It would be recommendable to establish - a MMU common for all the service depending on the crisis information and on the characteristics of the available imagery. EVALUATION – M3 RESULTS (USERS OPINIONS)

Emergency Management Service - The activation of the service is easy and very useful for - Copernicus EMS is still not widely known. organising delivery emergency aid and for getting a fast - Lack of proper communication channels or protocols overview about the situation. inside the country could lead to the Copernicus EMS - The quickness of the response and the broad amount of products not to be used. data used and produced are the most valuable aspects. - The capability of the service to track evolution of the emergency is highlighted as a main strength. Products - The Copernicus EMS reference and crisis maps are much - Some maps are provided later than expected. more complete and detailed than the alternative maps - The thematic accuracy of maps produced using satellite found. imagery can be lower than maps produced with other - The products are consistent. data sources - Huge potential in operational work. - Criteria for creation of the crisis information can be unclear. “We recommend and would activate again the service”

Dissemination Training Collaboration Future challenges

Emergency Management Future challenges in remote sensing related to emergency mapping

- Possible overlaps between the data produced by different services both inside and outside Copernicus shall be continuously revised in order to avoid duplication of data while ensuring that high value-added products are delivered. - The possibility that Sentinel-1 and 2 data offer to continuously monitor events such as floods and fires, opens the possibility to monitor these events at European level in the scope of other services rather than Copernicus EMS Rapid Mapping.
