2009: Towards implementation of the Global Earth Observation System of Systems data sharing principles (original) (raw)
Establishing common standards and requirements for Earth Observation management, access and sharing
This thesis was conducted and completed within the international project OBSERVE, which aims to help coordinate and intensify cooperation between the Balkan countries in the field of Earth Observation, which is a goal of paramount importance for the development and sustainability of the region the Balkan peninsula in the future. This paper has attempted to collect, organize and assess relevant material through the available sources and applications of the Internet, as well as from creditable national, international organizations and private companies which are an essential part in the evolution of issues on Earth Observation in a global scale. Accumulation and presentation of material in a wider field of Earth Observation was approached, such as education, sensors, data sources etc., as well as on international initiatives such as GMES (Global Monitoring for Environment and Security), the ESA (European Space Agency), the GEOSS (Global Earth Observation System of Systems), et al.

The transformation of earth-system observations into information of socio-economic value in GEOSS
Quarterly Journal of the Royal Meteorological Society, 2005
The Group on Earth Observations System of Systems, GEOSS, is a co-ordinated initiative by many nations to address the needs for earth-system information expressed by the 2002 World Summit on Sustainable Development. We discuss the role of earth-system modelling and data assimilation in transforming earth-system observations into the predictive and status-assessment products required by GEOSS, across many areas of socio-economic interest. First we review recent gains in the predictive skill of operational global earth-system models, on timescales of days to several seasons. We then discuss recent work to develop from the global predictions a diverse set of end-user applications which can meet GEOSS requirements for information of socio-economic benefit; examples include forecasts of coastal storm surges, floods in large river basins, seasonal crop yield forecasts and seasonal lead-time alerts for malaria epidemics. We note ongoing efforts to extend operational earth-system modelling and assimilation capabilities to atmospheric composition, in support of improved services for air-quality forecasts and for treaty assessment. We next sketch likely GEOSS observational requirements in the coming decades. In concluding, we reflect on the cost of earth observations relative to the modest cost of transforming the observations into information of socio-economic value.

The international land-cover community has been working with GEO since 2005 to build the foundations for land-cover observations as an integral part of a Global Earth Observation System of Systems (GEOSS). The Group on Earth Observation (GEO) has provided the platform to elevate the societal relevance of land cover monitoring and helped to link a diverse set of global, regional, and national activities. A dedicated 2007-2009 GEO work plan task has resulted in achievements on the strategic and implementation levels. Integrated Global Observations of the Land (IGOL), the land theme of the Integrated Global Observation Strategy (IGOS), has been approved and is now in the process of transition into GEO implementation. New global land-cover maps at moderate spatial resolutions (i.e.,

Access to earth observation data has become critically important for the wellbeing of society. A major impediment to achieving widespread sharing of earth observation data is lack of an operational web-wide system that is transparent and consistent in allowing users to legally access and use the earth observations of others without seeking permission from data contributors or investigating terms of usage on a case-by-case basis. This article explores approaches to supplying a license-based system to overcome this impediment in the context of the Global Earth Observation System of Systems. It discusses the benefits and drawbacks of the explored approaches and suggests an integrated legal and technological approach for supplying an effective web-wide sharing environment for earth observation data.

The purpose of this paper is to describe implementation of EnviroGRIDS GeoPortal as basic EnviroGRIDS tools. The EnviroGRIDS project is built on principle of European directive INSPIRE as it defines rules for SDI building. The focus of the current version of EnviroGRIDS GeoPortal is on discovery, view and downloads. In the next stage there will be implemented invoke services using Grid infrastructure and tools supporting Sensor Enabling Services. The system is satisfying all the above listed requirements called Uniform Resource Management System (URM). The main objective of URM is easy description, discovery and validation of relevant information sources. In order to achieve interoperability, the main software interface among each particular component has to be based on ISO standards and OGC specifications, following the INSPIRE Directive.

In many countries throughout the world, the use of earth observation data for environmental or societal purposes still remains underexplored, in spite increasing earth observation (EO) data provision. The root cause is mainly a still inadequate generic knowledge to use remote sensing data and derive information products. The GEONETCast data dissemination system of GEOSS, the Global earth observation system of systems, is steadily working towards removing barriers for EO data access and use. Efficient processing and analysis tools, accessible by end-users, need to be urgently developed in order to exploit the full potential of this global data dissemination and information system. The ITC GEONETCast Toolbox, an open access earth observation data retrieval and application development environment is presented here. It can act as gap filler in the knowledge transfer chain from EO data providers to the local end-users in the different societal benefit areas of GEOSS.
Earth observation is entering a new era where the increasing availability of free and open global satellite data sets combined with the computing power offered by modern information technologies opens up the possibility to process high-resolution data sets at global scale and short repeat intervals in a fully automatic fashion. This will not only boost the availability of higher level earth observation data in purely quantitative terms, but can also be expected to trigger a step change in the quality and usability of earth observation data. However, the technical, scientific, and organisational challenges that need to be overcome to arrive at this point are significant. First of all, Petabyte-scale data centres are needed for storing and processing complete satellite data records. Second, innovative processing chains that allow fully automatic processing of the satellite data from the raw sensor records to higher-level geophysical products need to be developed. Last but not least, new models of cooperation between public and private actors need to be found in order to live up to the first two challenges. This paper offers a discussion of how the Earth Observation Data Centre for Water Resources Monitoring (EODC)-a catalyser for an open and international cooperation of public and private organisations-will address these three grand challenges with the aim to foster the use of earth observation for monitoring of global water resources.

When setting up GGOS as a project, the IAG Executive Committee asked the GGOS Steering Committee to establish a relationship with IGOS-P. IGOS-P addresses a number of problems and components of Earth observing systems in the frame of specific Themes. The IGOS-P Theme process will also be an important mechanism for the development of the components of the Global Earth Observation System of Systems (GEOSS). Many of the burning questions related to the water cycle, the climate, global change, and geohazards cannot be solved without sufficient knowledge of mass transports throughout the Earth system and the associated dynamics. All these processes affect the three fundamental geodetic quantities, namely the Earth's figure (geometry), its gravity field and its rotation. Thus, GGOS is an unique contribution to Earth observation in its capability to provide detailed information on the dynamics of the solid Earth and its fluid envelop on all relevant spatial and temporal scales. Focusing on the observing system for the mass transports within the Earth system the suggested 'Earth System Dynamics' Theme has the goal to develop the science basis for and to facilitate the implementation of GGOS. The Theme will define the role of GGOS, the underlying strategy and its interface to the other components of GEOSS. The interaction of GGOS with the other IGOS-P Themes will facilitate the full exploitation of the geodetic contribution by all other global observing systems. The Theme will ensure that GGOS meets the user requirements both from the IGOS-P Themes and the nine societal benefit areas identified by the Earth Observation Summit II.
