at Geoweb 2009
“So far the impact of SDIs on the integration of data as a
ubiquitous component of the web seems low”
“There is not evidence that SDIs have increased the
market volume of government data by significant amount”

39. Clemens Portele
at Geoweb 2009
“Current OGC standards are only really accessible to geo
experts, not easily from broader web community”
“OGC web services based largely on an architecture and
approach to web services developed 10 years ago”

when partially implemented can succeed
What is, is wrong
Orgel's Rule: "Evolution is
cleverer than you are".

41. “If a dataset available on the web is in
a format that can't be indexed by
Google, does it make a sound?”

72. “Our taxes fund the collection of public data -
yet we have to pay again to access it. [Make] it
freely available to stimulate innovation”
The Guardian “Free Our Data” web site

73. sadly it’s not that simple ...
Taxes only pay half of the costs (in UK)
Costs are ongoing, not one off
Many competing priorities for tax money
All geodata is not equal
Commercial companies can profit

79. The US situation
No large scale “national map”
Utilities and local governments map themselves
Most cities are mapped many times
Significant map inconsistencies
