ENVIROGRIDS TOWARDS "BLACKSEA" CACHMENT REGIONS – CROSS-BORDER SDI FOR

WATER AND LAND MANAGEMENTKarel Charvat, Premysl Vohnout

Objectives

• The scientific aim of the EnviroGRIDS project is to assemble an observation system of the Black Sea catchment that will address several GEO Societal Benefit Areas within a changing climate framework. This system will incorporate a shared information system that operates on the boundary of scientific/technical partners, stakeholders and the public. It will contain an early warning system able to inform in advance decision-makers and the public about risks to human health, biodiversity and ecosystems integrity, agriculture production or energy supply caused by climatic, demographic and land cover changes on a 50-year time horizon.



Beyond state-of-the-art:

• EnviroGRIDS is clearly going beyond the state of the art in the Black Sea region by adopting a catchment approach and by tackling several societal benefits areas together. By using the most powerful computer network of the world it is clearly showing the direction on how to analyse the increasing amount of global data made available throughout the planet.



Beyond state-of-the-art:

• It is bringing crucial information in a relatively data-poor region on future scenarios of expected climate, demographic and land cover changes. Based on the outputs of these scenarios it is building geoprocessing services in key societal benefits areas that will be connected back to the GEOSS.



Key technological task

• How SDI and Grid could be interlinked

• To be able to use advantage of powerful computation capacities of GRID

AnviroGrids components



SWAT



gLite’s main components

• User Interface (UI): The place where users logon to the Grid

• Resource Broker (RB) (Workload Management System (WMS): Matches the user requirements with the available resources on the Grid

• Information System: Characteristics and status of CE and SE



gLite’s main components

• File and replica catalog: Location of grid files and grid file replicas

• Logging and Bookkeeping (LB): Log information of jobs

• Computing Element (CE): A batch queue on a site’s computers where the user’s job is executed

• Storage Element (SE): provides (large-scale) storage for files



EnviroGrids Geoportal



EnviroGrids Geoportal

• Platform, where EnviroGrids partners share their metadata and data

• Central access point for EnviroGrids SDI infrastructure

• Based on principles of Uniform Resource Management and Geoportal4everybody



URM principle

• The objective of URM is design and implements such methods and tools, which will support context awareness sharing of heterogeneous knowledge in distributed environments (data and metadata are stored on many different server).

• URM has to guarantee not only pure access to data, but their relation with tools for their visualization and analysis
