Place matters: the Location Strategy for the UK

Finally after an extended delay the Dept of Communities and Local Government has¬†published¬†the UK location strategy, Place matters. The blueprint for a UK Spatial Data Infrastructure (SDI), or an extended job application for someone in Southampton…

GSDI 10 – Despite best intentions, slow progress but a new outlook ?

For the last 15 years the Global Spatial Data Infrastructure Association (GSDI) have been working hard to co-ordinate national and local governments, NGO’s, international institutions and other organisations to develop local, national, regional and then hopefully one day a global GIS database along with the polices to access it. Last week I attended and made a presentation to the GSDI’s 10th Conference in Trinidad.

GSDI 10 Conference

With our planet finally becoming recognised as a life giving infrastructure itself to mankind, such attempts to develop better management tools cannot really be argued against, however despite the best intentions of all those involved success so far has been limited.

Although I presented on the potential of Geoweb search as new technological development that is relevant to the creation of SDI’s, almost everybody agrees the technical challenges remain the most solvable, it is the organisational issues which restrict the sharing of geodata, and the complexity and therefore cost of developing national and regional SDI’s which are limiting progress.

Perhaps part of the issue is that SDI’s often appear to be “Grand Designs”, the results of many years planning to produce truly comprehensive infrastructures ready to support any potential national or international need, perhaps a better model would be to take a more evolutionary approach developing systems built around the existing open standards (the OGC’s role has very important here) to solve particular domain or thematic problems, which could be consolidated to form an SDI at a later date. For example you could imagine an international systems designed to monitor sea level change as a result of Global Warming.

Although it would be fair to argue that this is the preferred route to developing SDI’s there are few practical examples in operation today.

The Grand Design approach does introduce an additional issue which is technology related, many of the current SDI projects are planned to deliver over decades, with technological developments continuing to move rapidly, it is difficult to plan to implement using a technology which will be obsolete years before the infrastructure goes live.., as it is today the best available standards as drafted by OGC are moving from basic http interfaces to the more web services friendly SOAP based interfaces, while the leading edge is looking to REST based interfaces.

For technical architects this is an almost impossible design choice.

So we need to move away from the “Grand Design” approach and build SDI’s organically and simply, perhaps making use of the new Global infrastructures that companies like Google and Microsoft have made available to bootstrap the technology, and deliver faster benefits and to make the case for more in depth infrastructures at a later date.

After all have not all GSM networks grown out to provide national coverage from initially covering the urban centres where the need was greatest ?

The delegates I spoke to at the conference remain committed to the importance of the task, and I think are open to taking different approaches, I was very impressed to see Chris and Justin from the Open Planning Project run an afternoon workshop on GeoServer which provided an interesting contrast to the ESRI workshop held in the morning, ESRI incidentally have done a great job supporting the GSDI Association since its early days.

INSPIRE Day – First impressions


A number of press releases including those from the Commission, the Finnish Presidency Website and the European Parliament all provide limited detail as to the final text of the INSPIRE directive, which was agreed late yesterday as a result of a formal conciliation process.

Although the actual agreed text of the directive does not appear to be available yet, it appears that organisations like OS will continue to be able to charge for access to data with some restrictions. Organisations supplying spatial data should be able to “to license them to, and/or require payment from, the public authorities or institutions and bodies of the Community”, but such licenses “”must be fully compatible with the general aim of facilitating the sharing of spatial data” and “be kept to the minimum required to ensure the necessary quality and supply of spatial data sets and services together with a reasonable return on investment”.

I would caution anyone reading too much into these early reports, the devil will be in the detail here.. and we should also not forget that INSPIRE is about a lot more than the licensing regime.

From now on the technical experts can get on with drafting the principles around which the infra-structural components that will allow spatial data to be shared can be built- in my mind the really important part of INSPIRE

– the creation of metadata
– the technology of interoperability
– the development of data services
– mechanisms to promote national co-ordination.
