Articles on Spatial Data Infrastructures
A. J. Wortley of the Wisconsin State Cartographer’s Office passed along the following through the Weary Mappers listsev (February 19, 2008):
- Abbas Rajabifard, Ian P. Williamson, Peter Holl, Glenn Johnstone – From Local to Global SDI Initiatives: a pyramid of building blocs
- David Maguire – Where Next for SDI?
- Exploring Spatial Data Infrastructures Workshop, Wageningen, The Netherlands, 19-20 January 2006
- Ir. Bastiaan van Loenen – How to Assess the Status of SDI?
- Ian Masser – The Future of SDIs
- Ian Masser – Multilevel Implementation of SDIs
- Ian Masser – Spatial Data Infrastructures: A SWOTS Analysis
- Garfield Giff and David Coleman – Funding Models for SDI Implementation: from Local to Global
For a very interesting critical analysis of the the SDI movement, visit the following posting by Paul Ramsey on his “Clever Elephant Blog”:
- Paul Ramsey – Why SDIs Fail
And, where does “vounteered geographic information” and SDI intersect? Puneet Kishor, Ph.D. candidate at the University of Wisconsin-Madison, passed along the following:
- Max Craglia – Volunteered Geogrpahic Information and Spatial Data Infrastructures: when do parallel lines converge?
- Volunteered Geogrpahic Information Workshop, December 13-14, 2007
Also of possible interest, a YouTube video launched recently features the Canadian Geospatial Data Infrastructure (CGDI) Interoperability Pilot – http://www.youtube.com/watch?v=YIZLc_qHYZc
A. J. summarized Masser’s trends as follows
*Shift from product to process model
- From data producers to data users
- From data producers to data sharing
- From centralized to decentralized structures
* Becuase of the number of stakeholders involvded SDI outcomes will be more like a collage or a patchwork quilt rather than a uniform picture. Key issues include:
- The multi-level structure of SDIs
- The governance of SDI implementation
- The emergence of new organizational structures
*Followed by Key Issues for the Future, in order of priority
- Creating appropriate SDI governance structures
- Facilitating access
- Building capacity
- Making data interoperable
The CGDI IP project developed a OGC Web Feature / Web Map Service partnership network across Canada, demonstrating a variety of scenarios involving closest-to-source update, access and use of public geospatial data.
