Eisenstein at a GIS conference?

Battleship Potemkin

It is rare indeed that you are treated to the famous Odessa steps scene of the classic Eisenstein film Battleship Potemkin at a GIS conference.. then Terra Future was not trying to be a normal GIS conference!

As I have often argued here, the GI industry is too insular in its thinking, and needs to look elsewhere to really innovate.. hence Terra Future.

Eisenstein’s classic silent film was presented by Daniel Erasmus, a fellow of the Rotterdam School of Management and co-founder and director of the Digital Thinking Network. He made the point.. that with most media we are familiar with today, the makers and the medium itself, is sophisticated enough to obtain a emotional response from their audience, who after-all could not be moved by the scene of the small boy trampled on the steps or the shooting of his mother by the Cossacks – but as Daniel pointed out when did you last see a website or digital content which prompted a similar emotional response in you ?

There is still some work to do.

Mike Liebhold is well known to the new generation of Geo hackers and the open source GI movement from his presentations at Where 2.0 and the Location Intelligence Conference. Mike focused in on the potential impact of both open source tools and data, and the importance of standards based, non proprietary storage of information, making the excellent point that it may be difficult to develop RDF based semantic web applications when the data is held in “closed” GIS systems.

Robin Mannings a returning speaker from last year, reflected on the convergence of ubiquitous computing, positioning technologies and geographic information to provide a platform for the next generation of GI applications – perhaps using the human body as an important part of the hardware of such a system. As might be expected,sadly, this was the only element of the whole day picked up my the mainstream press (The Daily Express) who described Robin as a “scientific astrologer” – Its enough to make you want to give up !!!

Daily Express

There were many more interesting workshops during the day which looked into other societal changes expected in the future and how the needs of the market for geographic information will change over the next decades. Look out for the Terra Future podcasts in the next month of so..

It is vital that as an industry we focus of better understanding the future needs of the market and continue the fundamental research in both Computer and Information Science. The innovation we have seen over the last year from the likes of GYM and the growing band of community driven mapping is after-all built on the work of the research of 30 years ago… GPS, Relational Databases, Network Topology, Remote Sensing etc.

I’d like to use this posting as a opportunity to thank everybody involved in another successful event and in particular to thank the speakers and delegates who really made the day the great success it was.

The Semantic web ‘lightbulb’ moment

Talk to most people in the GI industry about the semantic web, eyes glaze over or people try to move the conversation on to something else.
Why is this ?
The productive use of Geographic information online is an area where taking a semantic approach is useful, and many would argue vital, if we are ever to develop a true GeoWeb!

It does not help that trying to understand the semantic web involves understanding an impenetrable soup of acronyms and terms, RDF, OWL, SPARQL and ontology etc, however it really helps to have an expert to explain and there is no one better than Tim Berners-Lee who presented at yesterdays Terra Future event as reported by ZDNet.

Semantic tube map

For many people attending i think the real “lightbulb” moment in understanding what the semantic web was all about, was Tim’s slide of the semantic web as represented by a Tube map; after-all GI people love maps..

This really does encapsulate the need to link different types of data (the lines) semantically to extend the usefulness of particular types of application or user need (the stations).

Using the example above, a photo taken by Tim at the Ordnance Survey can be linked via its embedded time stamp to his calendar, which in turn can then be linked to the Terra future event he was attending which in turn could be linked to the address of the Ordnance Survey.

While each of these applications and their associated databases have been developed for specific purposes, by describing and making their contents available using an Resource Description Framework (RDF) description of their meaning (ontology) we can join up these databases.

You cannot underestimate the challenge or importance of a semantic approach to solving the problem of linking geographical databases, an approach of linking databases based on a single view of the world as characterised by the DNF approach can only take you so far.

My thoughts from the other excellent speakers who presented at Terra Future tomorrow..

United Kingdom – OSGEO

osgeo
Following on from last weeks FOSS4G2006 conference in Lausanne, OSGEO the foundation behind the development of open source GIS software is establishing a UK Chapter.

This is great news, as the UK GI community is not a great user of such tools (The OS included it must be said – at least at the moment) and increased awareness of the value of open source tools was one of the main messages to come out of the AGI technical SIG meeting on Open Source earlier this year.

For more details contact Chris Puttick at Oxford Archaeology.

GIS Show Tat.. (Swag to our US cousins)

Mike at the Journal of maps is collecting peoples recommendations for best and worst trade show gifts following his trip to this years AGI. Afraid the plastic TOIDS of the OS don’t rate very highly!

Tim Berners-LeeAs a contrast to a rather depressing AGI conference review of the failure of the UK GI industry to come up with a viable GI Strategy, in which Mike Blakemore compared efforts so far to Little Britain’s’ Vicky Pollard..

“No but, Yeh but, No but, like there is this spatial data – no shutup..”

I am looking forward to next weeks Terra future research event at the Ordnance Survey, at which Tim Berners-Lee is to provide his insight into the place geospatial data has in the web of the future.

There are still a few spaces left, so if you would like to attend email the conference office.

I’m sure a wider industry insight is vital, the UK GI industry needs to accept that the future development of geographic information will not be decided inside the confines of the current inward looking industry of today or for that matter any government generated strategy.

The use of GI is already pervasive… it has become so almost despite the attempts of the last 20 years of industry strategies, instead technological developments like the web developed by Berners-Lee have provided tools to connect users to geospatial data and is now allowing them to become data creators themselves – now that is really exciting !!!

Heavy lifting – The boring stuff behind Google and Microsoft ?

Reflecting on yesterdays plenary presentation at the AGI, and the report of it at ZDNet which completely ignored the presentations from the boring old vendors ESRI and myself!!, you would expect there to be much upset and insecurity as we all wave farewell to the GIS industry of the past replaced by the mainstream vendors…

I do sense a little bit of a wobble, but –

Of course the reality is that all the “new” exciting vendors Google, Microsoft, Yahoo etc are all reliant on the data produced by the primary data providers, who in turn need to use the tools and models created by the boring old vendors. This has become know as the “heavy lifting” part of the industry, it may not be glamourous and may be missed by the mainstream press but it represents the vast majority of activity undertaken using geographic information.

So thank you Google, Yahoo and Microsoft for doing what the GIS industry should have done, in making Geographic Information more accessible with simple, well designed tools – the rockets of the Geographic information, but the “professional” industry needs to now work even harder in providing the fuel !!!

ESRI GIS Google Earth virtual earth

Time comes to Google Earth

Just finished the plenary presentations at this years AGI conference, which actually nicely coincided with the latest revision of both Virtual Earth, Google Earth and the imminent release of ArcGIS explorer. For me the most interesting demo was the new Google Earth to be released tonight which brings a basic temporal capability, Michael Jones demonstrated animation of a GPS track over a period of time – a whole new way to use KML data !!

For me it also interesting to see the beginnings of the convergence between the GYM approach to Geographic Information and the “Established” GIS community – there is still some way to go, but ArcGIS Explorer is a great start.

I’ll upload my presentation later in the week if you are interested…

ArcGIS Explorer – the iceberg of GIS

James notes in his Blog the continued interest in the soon to be released ArcGIS explorer… seldom in the GIS world has a software package generated this much interest before launch. Part of this interest is no doubt fuelled by the relatively private beta program until now.. I guess in contrast to the initially similar Google Earth.

ArcGIS Explorer

For ESRI this is a different type of software product, Google have always been a “server” company, with massive amounts of server and bandwidth at their disposal and an operation well used to developing server based applications.

Although ArcGIS explorer looks and installs like a conventional desktop application, it is really a client for the large ArcGIS 9.2 server farm than ESRI have been building, and it is the development of this that controls the release cycle for the client.

Like an Iceberg, ArcGIS Explorer is the visible 5% of an application stack that remains below the surface, in the new Geography 2.0 world of GIS applications your GIS is only as good at the server which hosts it and the data which drives it.

AGI Conference… Make or Break ?

AGI Conference

Less than a week to go the the UK’s main GIS Show and full marks to the AGI, for putting together what I think is one of the most interesting conference agenda’s in years.. If this years range of topics and speakers is not enough to get “bums on seats”, it is hard to see what else the conference organisers could have done to produce a conference to meet the needs of the GI industry in the UK.

But there is the challenge.. the UK industry is mature and dominated by a small number of large vendors, the OS and ESRI(UK) really stand out, and most users are fully aware of what is going on in the industry from the web and personal contacts – yes the industry really is that small in the UK. The AGI also represents a wide range of opinions and interests, so its often difficult to see a clear direction in its activities.

The AGI should be commended for inviting the “new” players this year, in the form of Google and Microsoft, but there is also something of a “organisation gap” as many of innovators who are very active in the UK, the likes of Steve Coast and Mikel Maron, are not traditional GIS people so it is good to see the “non-GIS” approach to using GI represented by Tom Steinberg of mySociety.

For the AGI however success will not come from positive comments, the “Bums of seats” is an important element here, as the conference and exhibition has become the major revenue stream for the AGI.

So.. if you have not decided on attending yet, its not too late – remember if you don’t go this year there might not be a conference or even an AGI next year !!

UK Mash-up event

Mash up eventI blogged a few months ago in response to Charles Arthur on the perceived lack of UK mapping mashups. While I did not agree at the time with his position that lack of data was the major problem, I guess we must accept that he is right to note the lower profile of creating mash-ups in the UK compared to the USA.

This is a pity for whatever reason as the mash-up movement represents a potential hot spot for innovation in the Geospatial industry. To discuss the state of UK mashups the AGI, OGC and BCS Geospatial SIG are holding an event at the OS on the 20th October.

The Draft agenda includes the following topics..

  • What geospatial mash-ups are all about?
  • Background on Geospatial Mash-ups
  • Example Mash-up Application
  • Questions and Facilitated Discussion
  • Geospatial Mash-up Tutorial
  • How are we going to make use of geospatial mash-ups in the UK?
  • Enabling Data Sharing in Mash-ups
  • Panel Discussion: What does the future hold for mash-ups – single malt, blended or moonshine?

The event is primarily targeted at the existing GI industry – including those from commercial and non-commercial standpoints, and the expected audience will encompass both those with a strong technical perspective and those with wider strategic vision and market foresight.

We need to recognise that the concept of geospatial mash-ups is increasingly being discussed, but is not widely understood in the traditional GI community in the UK.

This event is designed to bring together the leading experts in the field, and to learn from them how the approach could be more widely applied across the GI industry.

As an industry we may well find this a challenging concept or simply characterise it as “putting pins on a map”, however it might also mark the beginnings of a wider trend where the ownership of information becomes much more distributed in the future…
