Disaster management is an area where the use of satellite data can literally make a difference and even save lives. Copernicus, the European Union’s Earth Observation Programme, has a dedicated service for this purpose – the Copernicus Emergency Management Service (EMS). The service is free of charge and available for emergency actors anywhere in the world.[h=3]Copernicus Emergency Management Service[/h]The Copernicus Emergency Management Service is one of the six main services that the Copernicus Programme, the European Union’s Earth Observation programme, provides on a global scale. The service supports crisis managers, Civil Protection authorities and humanitarian aid actors dealing with natural disasters, man-made emergency situations, and humanitarian crises, as well as those involved in disaster risk reduction and recovery activities.The EMS consist of five main components:
The EMS GloFAS system is the global counterpart of the European EFAS. It is composed of an integrated hydrometeorological forecasting chain and of a worldwide monitoring system that analyses daily results and displays forecasts for flood events on a dedicated web platform. To use the GloFAS Forecast Viewer, you will need to create a free account on the website. The website also has links to YouTube videos introducing the system and explaining how to use it, case studies for downloading and other information. Unlike EFAS, GloFAS is freely accessible to anyone.https://i1.wp.com/geoawesomeness.com/wp-content/uploads/2018/04/Glofas-2.pngGlobal Flood Awareness System (Copernicus EMS © 2018 EU, GloFAS)[h=3]European Drought Observatory[/h]The European Drought Observatory (EDO) is a new service released in January 2018. The EDO provides drought-relevant information such as maps of indicators derived from different data sources: precipitation measurements, satellite measurements, modelled soil moisture content and others. Graphs and Compare Layers tools allow for displaying and analysing the information and Drought News give an overview of the situation in case of imminent droughts.https://i1.wp.com/geoawesomeness.com/wp-content/uploads/2018/04/European-Drought-Observatory.pngThe Compare Layers tool of the European Drought Observatory (Copernicus EMS © 2018 EU, EDO)[h=3]The benefits * limitations of satellite imagery[/h]There are many advantages that satellite imagery can provide:
- Risk * Recovery Mapping
- Rapid Mapping
- Early Warning * Monitoring Systems for Forest Fires (European and Global)
- Early Warning * Monitoring Systems for Floods (European and Global)
- European Drought Observatory (EDO)
- Reference Maps, which show the situation prior to an event and are based on archive satellite imagery of the area prior to an emergency event;
- Delineation Maps, showing the extent of the event (for example, in case of wildfires, the perimeter and area of a burn scar or in case of floods – the flood extent);
- Grading Maps that estimate the magnitude of the damage after a disaster (for example, the severity of the burn in case of a forest fire, the number of buildings, roads affected by an earthquake and their damage grade, etc.).

- It allows to acquire information about difficult to access locations (e.g. remote, disaster and conflict-stricken areas)
- Radar satellites (such as the Copernicus Sentinel-1) can acquire imagery at night and irrespective of weather conditions (e.g. even when clouds are present over the Area of Interest)
- Large areas can quickly be assessed for damages to transport and building infrastructure *#8211; this can be particularly valuable in dense urban areas with large populations
- It is possible to monitor an area over a period of time to observe changing phenomena such as the expansion of urban areas or settlements, the movements of displaced populations, and the progress of construction activities
- Optical satellites can only acquire images during daytime, and image quality can be affected by the presence of clouds, haze or smoke. In many of such cases, radar satellites can be used, however not all mapping products can be produced using radar imagery
- The accuracy and quality of the mapping results can vary depending on the nature and scale of the phenomena observed. For example, in case of floods, the satellite overfly can be too late to capture the maximum extension of a flooding event
