Christchurch resolves data sharing issue with WSF(T)

New Zealand: Post 6.3 magnitude earthquake in 2011, one of the biggest problems of Christchurch City Council (CCC) was data interoperability and sharing. They adopted web feature services (WFS) but it resolved only half the problem of data sharing. It was one-way transaction only.

So, the central parties to the recovery (CCC, CERA, SCIRT) adopted WFS(T) where the ‘T’ stands for the transaction function of WFS which enables the client to not only interoperate with the data from CCC, but to make changes, and then return the changed data online, directly back to the CCC. Even though the parties involved are using different computing platforms. Re-engineering the spatial data exchange chains, in this way, introduced the potential for huge productivity gains and business benefits. However, there was a paucity of skills and tools to help invoke this level of sophisticated open interoperability.

Land Information New Zealand (LINZ) proposed an intervention. It suggested a workshop and invited the key parties to participate. A key facet of the LINZ proposal was to utilise international expertise and enable the NZ software engineers and GIS specialists to explore the possibilities, face-to-face, for 3 days in Christchurch, exploring all the options that could achieve a functional WFS(T). The LINZ also invited the lead architect of WFS, Peter Vretanos.
