I had the opportunity on Monday (6 December 2010) to attend a great workshop held in Wellington. This started off with a set of three presentations by Mark Reichardt who is the President and CEO of the Open Geospatial Consortium.

Mark presented a number of presentations during the morning, starting with CEOs, followed by one focused on OGC and Disaster Management, as well as finishing with An Overview of OGC Standards and Programs. Hopefully these will be publicly accessible in Google on portal.opengeospatial.org – I’ll put links up when the files are openly available.

I got a great buzz to see Sahana, OpenStreetMap, CrisisCommons and Ushahidi mentioned in slides by Mark, and these event got coverage in the presentation to the invited Government CEOs at the breakfast session. In the open presentation on OGC and Disaster Management in the morning, Sahana got its own slide and was recognised for incorportating various OGC standards including Web Map Service (WMS), Catalogue, KML , Web Feature Service (WFS) and the Coverage Service. It is great to see the significant geospatial efforts that the likes of Mifan, Fran, and David have put in – amongst others and sorry I can’t recall everyones names!

I also talked about my experience around geospatial data and building safety evaluations following the Canterbury earthquake, and there seemed to be some real interest in using that as a possible test bed geospatial project that we may be able to undertake here in NZ. I must get onto blogging more about that.

As always, it was a great opportunity to catch up with some colleagues that I hadn’t seen for a while, and it has been particularly reassuring to see some great minds that were thought lost with the State Services Commission restructure now turning up in Land Information New Zealand. LINZ taking on these people definitely sends a positive signal about open data and standards. In particular I want to note Richard Murcott who is now the Geospatial Standards Leader at LINZ.

Anyway – what were some of the points I took away from the workshop?

• It sounds like Land Information New Zealand is going to become a full OGC member in 2011.
• The OGC GeoSMS standard is going to be coming soon! A discussion document from Freburary 2010 on OGC GeoSMS is available here (link to agreement page, then pdf download). This will be great to have a GeoSMS standard to work to, as we had created our own in Naval Postgraduate School Disaster Relief Experiments previously.
• Mark highlighted that demonstrating standards – through test bed projects and the like – is one of the most important aspects of standards promotion.
• The Taiwanese have been doing quite a bit of work with OGC, and have been doing some very interesting debris flow monitoring projects with OGC Sensor Web. There is supposed to be a good pdf available that outlines the Taiwanese work with Sensor Web.
• Geosynchronisation. OGC has within the last month announced the formation of a GeoSynchronisation Service Standards Working Group. This of course has a lot of potential – not only for taking OpenStreetMap data out into the real world, editing it, and coming back and syncing it later, but also of course for emergency management. I intend to watch this one quite closely.

One of the closing quotes of the emergency management presentation came from the Chairman of the OGC, David Schell.

What the OGC is doing is facilitating a common picture of reality for different organizations which have different views of the reality, the disaster, the catastrophe, that they all have to deal with collectively

The use of OGC standards is probably the only clear path forward towards a Common Operating Picture – well, one that has anything to do with location anyway.

In the afternoon, Richard Murcott of LINZ led a workshop discussing standards and interoperability.

One of the big takeaways for me was the model of Conceptual Interoperability from Simulation Theory. Basically it builds up from nothing – no interoperability, to a state of full interoperability – where fully conceptual models are used to integrate data consistently from multiple sources.

Of course, we are a long way from this in emergency management, a lot of the current interoperability we have is at level 2 which is only a common data format. The OASIS work with EDXL is taking us a step higher (level 3) with increasing semantic interoperability through the use of more clearly defined standards. I think there is a very long way to go using this model though to ensure we have interoperability that considers methods and procedures (level 4), assumptions and constraints (level 5) to a “fully specified but implementation indepentent model” (level 6).

Some other quick takeaway points that I and others came up with:

• There is a spectrum of the reason for interoperability – from selfish to altruistic. A selfish organisation wants to bring any data into its system and processes, whereas a truly altruistic organisation wants only to publish and share information.
• There is a spectrum of the management approach of interoperability – from adhoc/chaotic to extremely structured. Some organisations want full control over how interoperability is managed that require a very structured and formal approach, and even agreements or MOUs. At the other end is complete anarchy and chaos.
• Risk aversion is a significant barrier to interoperability, so clearly taking a risk management approach to interoperability is likely to provide a better means to manage risks, and hence make true interoperability more acceptable to management.
• Restrictive licensing of standards creates barriers to entry. Nothing new there.
• Data sets provide an excellent focal point for collaboration and communities may well form around a released data set. E.g. NZ Open GPS Maps project around released LINZ roads.

One of the final points Richard made in closing was more targeted at New Zealand in general, and certainly a sentiment I think we should take to heart. New Zealand, as a country, needs to behave more like a city of 4 million. Dispersed from Northland to Southland we pack nowhere near as much punch than if we better bring our expertise together from across the country. If we want to be more successful on the world stage, then we need to lose our small town mentalities, and start thinking bigger and broader!

I haven’t done some political blogging for a while, but figured I’d briefly wade in with a couple of comments re: Michael Cullen’s Budget.

One particular comment I’d like to raise and highlight as a point of difference that National could make. In Cullen’s Budget speech he stated that the structure of the income tax system would be simplified.

This programme consists of a combination of a cut in the bottom rate of income tax, threshold changes, a simplification of the structure of the income tax system, a bringing forward of indexation of Working for Families and a forecast second round of such indexation.

In theory the current personal tax system has three rates: 19.5 per cent up to $38,000, 33 per cent from $38,001 to $60,000, and 39 per cent above $60,000 a year.

In practice, the operation of the Low Income Rebate for earned income creates an effective four-step scale with the bottom step split into two: 15 per cent up to $9500 a year and 21 per cent from $9501 to $38,000.

At the completion of the Budget 2008 tax-cut programme the rates will be 12.5 per cent on the first $20,000 of income, 21 per cent from $20,001 to $42,500, 33 per cent from $42,501 to $80,000, and 39 per cent above $80,000.

Call me blind, but aren’t we starting with a four-tier system and ending with a four-tier system? What is simple about that? If Cullen was serious about simplifying the income tax system he would look at removing one, and ideally two of the tiers. This would create a far simpler two-tier structure. Why not have a lower tax bracket for all income up to say $20k-$30k, and a higher rate for everything over that bracket?

For a while I was keen on a single income tax rate, but I have come to recognise that there does need to be some break given to lower income earners to recognise that tax can be more significant.

A simple two-tier income tax system would achieve true simplification. One has to wonder if Cullen only wants to keep complexity in the tax system to make juggling the numbers easier.
