CEOS Working Group on Information Systems and Services - 2

Overall Discussion Points

Mike Clarke has engineered a unique occassion for a wide range of SDI’s and CEOS WGISS to come together to discuss issues of common interest.

It is clear that, indeed, the work of the SDI’s is compatible with, and relevant to WGISS

The SDI’s are addressing the a range of technical issues relevant to WGISS

how much needs to be defined

They are approaching these issues from different thematic and policy perspectives

this raises the perspective of possible collaboration what areas could we collaborate on? how could that collaboration be implemented?

Characteristics Of An SDI – How Does It Relate To WGISS?

The “Lauritson Question” – the “Fisher Response” – the “Churchill Questions”

Characteristics of an SDI (after Fisher) Questions (Churchill et al) Access

A series of underlying services that support – Resource Discovery WGISS does this?– Resource Evaluation Does this include

analysis/models?– Resource Access Does WGISS fully do this

Framework/Data Includes formats, inter-use? Standards

SCOTS (Standards based COTS) Standards organisations work Open interfaces e.g WMT Get Map with input from WWGISS

Policy Enables sustainability Should WGISS be involved here?

Partnerships

Further Discussion PointsWhat messages can we take forward to CEOS WGISS? Should we maintain close links with the various other SDI’s?

There are clear areas of common technical interest We can all benefit from the cross-fertilisation of ideas and techniques (helps to

ensure coherent developments whenever possible) However, good intentions do not always produce results; if we do decide to

maintain close links, these should be on concrete subjects with appropriate concrete mechanisms

Indeed, this is part of, and can help develop WGISS’s discussion on links to the wider GI world, to standards organisations, commercial organisations, etc

If we should maintain close links, how we will achieve this? Cross attendance at each others meetings? Common meetings and workshops? Regular excahnge of technical information?

What are the subjects we should maintain links on? Policy: data policy? Policy imperatives to have Data services / holdings? Business Case: killer applications, involvement of users, demonstrations? Technology: technology watch, technical devlopments, standards?

Specific Discussion Point: Policy Data Policy:

Workshop Conclusion: – Data policy a key to the success of a SDI, and that clear,

underlying data policies need to be defined Discussion Point:

– Should WGISS start to take part in this discussion?– If yes, how could we liaise with the wider SDI world?

Policy as a Driver: Workshop Conclusion:

– Addressing sectorial (strategic) policy as a main driver for a SDI can be an important element of success; International Treaties are important drivers

Discussion Point:– Can the various SDI policy drivers contribute to on-going WGISS

drivers (international science programmes)?– Can the various SDI’s directly contribute to pilot project (testbed)

intiatives (global forestry, disaster management....)?

Specific Discussion Point: Users Involvement of Users

Workshop Conclusion: – Customers for the information to be produced should be involved

at the earliest stages of the development of SDI’s Discussion Point:

– How can WGISS learn from the direct experience a number of the presented SDI’s have of the direct inolvement of users in their development (meteorological, antarctic, biodiversity, oceans, geology....)?

Demonstrations: Workshop Conclusion:

– Focussed, and limited demonstrations may be a good way forward in developing the business case for SDI’s

Discussion Point:– Can joint demonstrations be envisaged between WGISS and other

SDI’s?

Specific Discussion Point: Technology

Development: Workshop Conclusion:

– Keeping up with a very rapidly developing technology is extremely difficult– There are a lot of tools out there, which are keeping up with technology, and

are freely available. Can be captured and promoted through cookbook. Discussion Point:

– Can exchange of technology developments between other SDI’s and WGISS be foreseen?

– Can joint developments of required technologies be foreseen?

Standards: Workshop Conclusion:

– With the rapidly developing technology, standards are falling well behind the current status

– De facto standards are emerging to keep pace with the development Discussion Point:

– Is there benefit in joint submissions to standards organisations?

CEOS Working Group on Information Systems and Services - 8

Specific Discussion Point: Technology

Interoperability: Workshop Conclusion:

– Satellite data is one of many sources of spatial data in any SDI.

Discussion Point:– Are SDI’s (WDCs....) receiving full benefit from Satellite

programmes?– How are we measuring the suitability of space data products for

interuse with other data?
