The enviroGRIDS project – facts

Founded by the European Commission FP7 framework (Theme 6:environment)

April 2009 – March 2013

Total budget of €8.1 mio. (€6.2 EC contribution) and 1367 man-months

27 partners, coordinated by University of Geneva




Generic technical objectives

gap analysis developing a grid-enabled Spatial Data Infrastructure (SDI) spatially explicit regional scenarios of development modeling of large scale, high resolution distributed hydrologic

processes develop access to real time data from sensors and satellites develop early warning and decision support tools at regional,

national and local levels Build capacities in the implementation of many new standards

and frameworks

What is a Spatial Data Infrastructure?• SDI provides a basis for spatial data discovery,

evaluation, and application.

• Includes the following elements:

- Geographic data,

- Metadata,

- Services,

- Clearinghouse,

- Standards,

- Partnerships.


Challenges when sharing data

Many “islands” of data of different formats and quality.

Finding existing geospatial data is difficult.

Spatial data from different sources cannot be integrated due to:

- Incompatible information models & encodings.

- Non-interoperable information systems.

- No harmonization between datasets at different geographical scales.


Challenges when sharing data

Re-use of spatial data is actually hard to achieve:

- Complex data integration procedures.

- Costly reproduction and redundancy.

Data policy restrictions:

- Unclear access rights and licensing policies.

- Missing pricing models.

SDIs are about facing the challenges and connecting heterogeneous data sources.

Gridification of SWATWe plan to:- gridify SWAT to run on the EGEE infrastructure as a

geoprocessing service to be called from various clients such as SWAT users or web clients.

- Use ganga to easily switch among computational resources

easy-to-use frontend for job definition and management, implemented in Python


Gridification of SWAT-CUP

Program for sensitivity analysis, calibration, validation, and uncertainty analysis of a SWAT model


Launching jobs from within ArcSWAT


Grid-enabled SDI

SWAT input data sets may:

• be stored on a local SDI

• stored and replicated in a distributed filesystem on the grid

• called through web services at run time

SWAT output data sets may be stored on the grid for future use


Pushing for standardization

The grid-enabled SDI, will push for standardization among all countries within the Black Sea catchment

A strong objective of EnviroGRIDS is to build capacities in the implementation of many new standards and framework


Infrastructure for Spatial Information in the European Community

a European Commission initiative to build a European spatial data infrastructure beyond national boundaries.

INSPIRE

EnviroGrids VO?

Starting to build our pool of resources:• At partners sites• Using forthcoming desktop grid at university of

Geneva 1500+ PCs

Alternatives:-joining existing VO (e.g. ES VO, biomed VO)

Ensuring long term access to data


Involvement of the public

IBM World Community Grid (volunteer computing)

A good way of having the public of the region participating

ChallengeNeeds to find the good application (jobs needing small amount of input/output data)


enviroGRIDS


Talking about Landsat (satellite) data:

“In spite of the great need for that information, the vast majority of those images have never fired a single neuron in a single human brain. Instead, they are stored in electronic silos of data.”

The Digital Earth (Al Gore, 1998)
