By popular request here is the presentation I gave at last week’s GI-Forum in Salzburg. A great conference which I recommend if you are able to attend next year, 1000 GI people in one of Europe’s most attractive cities = success !

Not sure the slides will make much sense on their own, but please get in touch if you have any comments.

If so, can you tell  me what’s wrong with this answer taken from a question asked in the House of Lords via the excellent theyworkforyou website…

UK: Coastline

House of Lords

Written answers and statements, 23 June 2010

Lord Laird (Crossbench)

To ask Her Majesty’s Government what is the length of the United Kingdom coastline in miles at (a) low, and (b) high, tide; and what are the lengths of the coastlines of (a) England, (b) Northern Ireland, (c) Scotland, and (d) Wales.

Baroness Hanham (Parliamentary Under Secretary of State, Communities and Local Government; Conservative)

Information provided by Ordnance Survey for Great Britain and by Land and Property Services, an agency of the Department of Finance and Personnel for Northern Ireland, indicates that the lengths of the coastlines at mean high water (MHW) and mean low water (MLW), (mean high water springs [ordinary spring tides] and mean low water springs in Scotland) are:

These coastal lengths include all offshore islands, and land areas which are above MLW.

The precise length of coastlines will vary from time to time due to natural and gradual changes arising from coastal erosion and silt deposition.

I finally got the chance to watch the Apple WWDC keynote last night in my living room on the Apple TV, now that statement qualifies me as an Apple fanboy in itself.  I have seen many stevenotes over the year, even one in person at a Macworld in New York a few years ago, but his performance at this years WWDC was quite brilliant.

So for anyone who makes presentations what tips can we learn from the master.

1 ) Steve always begins his presentation by setting the context, framing the market for the new product announcement. This he does by quoting some very carefully chosen and very selective statistics..so for example iPhone has 28% US smartphone share, compared to windows at 19% ? and Android at 9%, the next slide however drops Windows and compares mobile browser usage with iPhone having  a massive 58.2% compared to Androids 22.7% – I wonder what happened to all those windows smartphone users ?

2) Steve is the master salesman his description of the iPhone 4 is a work of genius, “a quarter thinner for something you did not think could get any thinner”, the retina display so high resolution your eyes cannot see the pixels anymore – quite brilliant.

3) When things go wrong Steve keeps his cool because he knows his stuff, this keynote will be remembered as the one when the wifi broke. There has been much debate as to why, but the end result was that Steve’s demos did no work very well. Rather than panic Steve unlike many CEO’s was able to diagnose the issue on stage and explain it, and then later on make a joke of it asking people to switch off their own wifi devices so he could continue with the demo.

4) Make people believe something is new by selling it better, so Facetime offers the ability to carry out a 1 to 1 video conference using two iPhones 4′s on wifi, "we have been waiting a long time to make this happen", eh no.. I remember calling my wife over the vodafone 3G network using a pair of different Sony Ericsson phones five years ago. Video calling did not really take off, the technology and the public was not really ready for it.

To make the public ready it needs to be sold not on the basis of technology, which the early vodafone live very much was, but the emotional strength of human communication. Compare the vodafone PR shot here with a still from the Facetime video ..

A lonely businessman away from his baby, stuck in a hotel room –  now that’s a market..

There are two really significant technology advancements that are of note and that may not have got as much attention as facetime or the retina display..

Firstly the iPhone 4 is the first quad band iPhone supporting the 900Mhz HSDPA band used extensively in the UK but not previously supported on iPhones. Wonder why your iPhone 3G coverage was often worse than other smartphones ?

Secondly supplementing the digital compass the 3-axis gyro will allow devlopes o crate much better augmented reality applications, potentially solving many of the pose problems suffered by the current generation of smartphones. In the future who knows maybe some clever software will turn the iPhone into a simple Inertial Measurement Unit (IMU) which could allow indoor navigation applications ?

So once again the great snakeoil salesman has got me and I will be taking delivery of an iPhone 4 of thursday as my home phone to sit alongside by Nexus One work phone.

Now which network….

A great early example of the value of the new TfL train prediction API, a map of the ‘Real time” locations of Tube Trains.

Produced by MySociety ace Matthew Somerville a really neat demo and another example of the value of releasing government datasets, and in this case an example of an occasion where an API is more useful than the raw data.

Mapnificent LondonI have for a while called out for some new cartographic approaches to communicating information which make use of the radically different capabilities of electronic displays compared to paper. To be fair I suppose the palette of tools available to the online cartography have been limited, and the state of the art was probably some of the renderings of OpenStreetMap data developed over the last year or so.

With the release at Google I/O this year of the V3 Maps API and styled maps functionality these tools are becoming more accessible, and one of the early results is a beautiful map produced by Stefan Wehrmeyer in Berlin. His Mapnificent London map uses the styled map API to show London by night, and then with full credit to the famous mapumental map, dynamically displays journey times if you used the extensive London night bus network.

The dynamic aspect makes this map really interesting by simply dragging a time slider bar you are presented with a great deal of information is a clear and simple way, something which would be difficult to achieve with traditional static cartographic techniques.

Hopefully the first of many new dynamic maps..

I’m writing this sitting in the back of the room, waiting to make a presentation during the annual Space Show in Toulouse, the closest Europe comes to having a city whose sole export is technology

Seems, like I have been running around almost constantly for the last month, but tomorrow I have made a little time for myself to brew a pot of coffee sit down and watch all of the Geo Developer presentations on youTube from last months Google I/O conference in San Francisco.

If like me you missed the event this is a great opportunity to catch up with things like the Latitude and Places API, developing mobile apps using the v3 Maps API and of course my favourite the new Styled Maps feature.

Kick back and join me before the football starts !
