2 Final Report capability of existing missions. Nevertheless many existing applications are identified that can profit from Geo-Oculus, some can significantly profit or first become possible in an operational manner. The range of applications covers a large variety of remote sensing applications of the Earth's surface. For the structuring of the documents and to account for the expertise of and task of the consultant it has been chosen to categorize the applications into four fields of services, the: • Land Applications, covering all services related to the Earth's solid surface, including the land part of the coastal zones and disaster monitoring; • Marine Applications, covering the services related to the marine ecosystem, hydrology, oceanography, sustainable exploitation of marine resources and anthropogenic forcing and threat to the environment; • Traffic and Security at Sea Applications, covering marine operations, natural threat to the citizen and law enforcement related to the oceans; • Earth Science Applications, covering climate research (esp. role of the ocean), the Earth's radiation budget, monitoring of rapid events and data assimilation. For all applications the necessary and optional products have been identified and defined to a sound level of detail to provide the required technical parameters for the definition of the mission and the instruments. A threshold, a breakthrough and a goal value have been given for most of the parameters, if available through generally accepted literature. Important synergies Geo-Oculus provides strong assets for synergies with current and planned European EO-missions. The optimisation for cloud cover, which is considered as a central benefit of Geo-Oculus, is only possible with support data from Meteosat and EPS. On the other hand, Geo-Oculus can support other missions to improve quality of service. Some synergies, receiving and supportive, are listed below: Receiving synergies: • Real-time cloud cover information from Meteosat and EPS • Fire presence by any means • Highest resolution support data e.g. for disaster monitoring from SPOT, Pleiades, Ikonos etc. Supportive synergies: • Oil slick verification • Gap filling due to cloud cover for Sentinel 2 & 3 • Fine scale and real-time spotlight support to meteorology, e.g. for severe weather events These synergies are considered as a prerequisite for the selection of mission objectives. Selection process In a preliminary selection process based on the criteria "Political Importance", "Institutional / Non-Profit Importance", "Commercial Importance" and "Suitability of Geo-Oculus" a set of applications was proposed to ESA and in consultation with ESA the preliminary mission objectives were set. These were used for sizing of the system. For that reason, only sufficiently elaborated applications with available technical requirements could be taken into consideration. Nevertheless, these mission objectives represent a realistic case, demanding a challenging system without overtightening the requirements. Page 2-2 Doc.

2 Final Report 2.3 Mission Objectives The mission objectives for Geo-Oculus that have been selected in consultation with ESA based on the survey described in 2.2 are: Primary Mission Objectives: • Disaster Monitoring • Fire Monitoring • Algal Bloom Detection / Monitoring • Water Quality Monitoring with respect to European Regulation Secondary Mission Objectives: • Oil Slick Environmental Information • Erosion / Sediment Transport on the European Shoreline Monitoring An overview of each of the mission objectives is given in the following: Disaster Monitoring Service - Primary Objective The disaster monitoring service is aimed at providing overview information in case of natural hazards with significant geographic extend. Based on the findings of PREVIEW (2006) on the priorities adopted for Civil Protection activities of the Member States concerning the risk management and the suitability of high-resolution imaging, the following hazards are considered for the Geo-Oculus disaster monitoring service: • Large landslides • Floods • Windstorms It is the goal of the disaster monitoring service to deliver geospatial information with short acquisition delay and timeliness of less than an hour on demand of civil protection organisations. This service shall be tailored for early warning, crisis, and post crisis support to the users. Doc. No: GOC-ASG-RP-002 Page 2-3 Issue: 2 Date: 13.05.2009 Astrium GmbH
