If you can’t link to it… does it exist ?

“If a tree falls in a forest and no one is around to hear it, does it make a sound?”

So goes the well-known philosophical thought experiment,  however rather than a discourse on observation and perception I’d like to hijack the experiment for an argument I have been making on and off for the last couple of years and which was  well summarised in a tweet summarising my point last month..

Does information published on the web which is not easily linkable actually exist ?

Well of course if I chose to publish my large spatial database of whatever using a Web Feature Service or some other application server the data actually exists, but as far as users of the web does it exist if I cannot find it using web search or more importantly as far as the way the web works cannot link to it?

This issue of making the so-called Deep Web more discoverable is still challenging , efforts such as the sitemap protocol have had only limited impact.

I would argue for the geospatial community in particular we need to take a more fundamental look at how we make information accessible and linkable on the web.  We need to start from the basic use case, common if you think about it but radical it would appear in the GIS world..

I need to let people link to each record in my spatial database and to share that link..

This actually requires perhaps a much more granular approach to making spatial data available, something that nearly got started with OS Mastermap but which for many issues was never fully implemented.

Rather than publishing online a database of railway station locations in the Netherlands and expecting a user to then query the database for  “Amsterdam Centraal Station”,  publish the database giving each record a URI so for example Amsterdam Centraal Station becomes;

https://brt.basisregistraties.overheid.nl/top10nl/id/gebouw/102625209 

Now this is something I can paste into an email, tweet or even share on Facebook !

Kudos to the Dutch Kadaster for taking this approach and providing this example, Ordnance Survey you could do the same ?

This approach also results in such data becoming part of the “mainstream” web indexable and searchable, but I argue the key benefit is the “linkability”

The Spatial Data on the Web best practice document, something of course I recommend you taking a longer look at provides many excellent practical pointers to taking this type of approach.

Maybe really this is just an issue of semantics rather than publishing spatial data should we be talking about sharing spatial data ?

Making SDIs work !

Excuse my voice I had flown in the night before and I had a case of “airplace flu” and two hours sleep, nevertheless a reasonably coherent discussion of the future of Spatial Data Infrastructure development for the new Geobuiz channel.

Inspire a moonshot not a blueprint ?

A few weeks ago I had the pleasure to take part in the ImaGIne conference organised by the European Umbrella Organisation for Geographic Information in Dublin. The conference although not very well attended did contain both excellent presentations and perhaps unusually great discussions which really seemed to address some of the key challenges of using geospatial technology in Europe.

A talk on the use of Geo in the context of Europe brings us inevitably to the Inspire Directive and it’s progress and impact. Inspire which came into force almost exactly six years ago is the programme to build an European Spatial Data Infrastructure by October 2020.  Inspire was the topic of much discussion at the conference as this year a number of important articles of the directive must be implemented.

An obvious concern expressed by many, included myself, is the difficulty of legislating to build an information system over such a long time.  Developing quite prescriptive  rules as to how to share information is almost impossible with the speed of technological development online.

The issue is perhaps more problematic when you think that many of the ideas and principles enshrined in the Directive were developed during the five years leading up to 2007, a time before social networking, big data and the mobile internet.

In hindsight of course perhaps a less rigid approach which articulated the principles of sharing environmental data and their benefits might have been a better outcome, concentrating on policy issues around reuse of information rather than the actual mechanics. And yes of course I accept the point that without harmonisation of data and the creation of (limited) metadata data sharing is difficult, nether-less often inspirational ideas are best when they plant the seed of an idea and accept that how the idea is accomplished may differ.

Before the conference in Dublin, I was asked to speak at a meeting at the European Commission in Brussels and was asked to bring along a object which to me represented the Inspire programme. Feel free to suggest your own in the comments, but I brought along my rather battered copy of Jules Verne’s “From the Earth to the Moon“.

Along with HG Wells, Verne is credited with pioneering science fiction, and with this book although published in 1865  demonstrates the power of a inspiration idea. Both Wernher von Braun and Robert H. Goddard cite the book as a catalyst for their interest is rocketry and space exploration. Published 100 years before the actual moon landings Verne was able to make some uncanny predictions, correctly suggesting that three men would leave the earth in a capsule launched from Florida after much political horse trading!  Of course technology moved on and 1969’s great achievement was made with liquid fuel rockets and computers not the large cannon suggested by Verne – still the idea was the inspiration !

So perhaps we should look at the Inspire programme in the same way, a moon shot idea that today may be achieved is different ways to at first considered..

My Talk at the INSPIRE 2011 Conference

I was invited to speak at the annual INSPIRE conference in Edinburgh last month. INSPIRE remember is the European Commission programme supported by national legislation to build a Spatial Data Infrastructure (SDI) for European Environmental data. I was asked specifically to address how INSPIRE can foster innovation and “smart growth”.

These are excellent topics to discuss in relation to SDI development, SDI’s I’m afraid are still designed and where built operated almost solely from the perspective of data providers rather than users. INSPIRE is in some ways a victim of this mindset, although there is a clearly defined user in the form of European Commission organisations. Here the issue is one of scope to really maximise the innovative potential INSPIRE, organisations need to gone beyond the strict requirement to make their information available to the Commission and share as widely as possible by adopting the principles of Open Government Data.

Google Earth Google Maps INSPIRE Thoughts

So you want to use Google Earth to…

One of the most common questions people ask me, is “Can we use Google Maps to do xxx” , or “Can I use Google Earth in..” in most cases the answer is usually a resounding “YES”, but there are usually some conditions on use and for some uses the answer I’m afraid is no. For the past few years I have pointed people to the Geo Permissions website, which has been updated to now include a Permission Tool , a wizard interface to take your step by step through the permissions process.

I was at the INSPIRE Conference last week discussing amongst others things the licensing of geospatial data for shared Spatial Data Infrastructure projects, I made the point that increasingly data would be made available via online services and perhaps an additional way of reducing complexity is look at similar tools to explain access via future online services – the key insight.. to be user rather than producer focused !

AfricaMap – GSDI 2.0 ?

As highlighted by Keir on the excellent Google Maps Mania last week,  AfricaMap is an interesting  attempt to build a repository of geospatial data about Africa, developed by the Center for Geographic analysis at Harvard University.

 

Map of Africa
Map of Africa

What is interesting about this site, is both the scope of the project and the approach taken.

From decades many individuals, groups and organisations have been trying to develop Spatial Data Infrastructures (SDI) at a regional or global level (GSDI), with it must be said very limited success so far.

Unlike many previous attempts at developing a portal to a regional SDI, Africamap tries to hide as much complexity as possible from the user just presenting a map display and a search tool – Great start after-all I would argue that more than anything else a SDI is really just an example of a vertical search application.

But no.. You have been mislead dear user, just searching for something like “Sudan Population” or Nile Delta won’t give you any results – you need to select which maps layers (data-sets) you need to search first. This is not unusual in SDI implementations, but it would be like having to tell a generic web search tool, which websites the information you are looking for can be would.

This approach is, I believe, the result of a culture of system design that is dominated by data providers, not users. The user interface here has been influenced I’m sure by the creation of the metadata that  SDI convention states is always the first step in building an SDI.

It’s not that the data is not available, it’s just that the approach taken so far by the SDI community makes its inaccessible to almost anyone other than the original data provider or someone who has the time to work out which map layers should be searched.

So some may argue, this and similar sites are designed for specialised users, who have intimate knowledge of this type of data and how it is structured, even so there is no reason to make access to this more difficult than it needs to be..

OK rant over, from a technology and tools point of view Africmap demonstrates what is possible now with a freely available web tools and open standards based geospatial services, and without doubt the team at Harvard should be congratulated for doing the hard back office work to provide access to all this important information from one place.

This is not yet GSDI 2.0 then, but GSDI 1.5 and a pointer to the direction which ultimately may finally deliver on the GSDI vision.

To understand more about the efforts to create a GSDI, visit the GSDI conference this year in collaboration with the EC’s third INSPIRE conference in Rotterdam in June.

GIS INSPIRE neogeography OGC Thoughts

Neogeography.. it was just a dream..

Imagine waking up in the beautiful Portuguese city of Porto and finding out the past two years of your life were a dream… All that talk of GeoRSS, Map Mash-ups, KML, User generated My Maps, The GeoWEB and Paris Hilton were all part of a dream.

We it felt a bit like that on the first day of the annual European Commission GI and GIS Workshop. Over 200 hundred GIS users from Public Sector Organisations and a few private sector ones are together meeting to discuss the impact of the INSPIRE directive now that it has been passed by the European Parliament.

ECGIS workshop

During this first day the web 2.0 buzzwords of neogeograhy were notable by their absence.

Now I am actually less disappointed that I might have been, let me explain why…

INSPIRE is, contrary to all of the fuss last year drummed up by some in the UK, quite tightly focused on the supply of harmonised environmental geospatial data to the institutions of the European Commission, by public sector organisations in the member states. – There is no “public” interface here and the citizens are not seen as major customers for INSPIRE services.

As such you can think of this as a complex back office system for European Government, as much an Enterprise GIS for Brussels as a Spatial Data Infrastructure. So key to success will be clear definition of requirements and well specified system design.

Now here is the rub, despite the fact that much of the INSPIRE directive is not expected to be implemented until at least 2010, it is been designed now and must used well specified and recognised standards – things like the ISO 19100 series of standards developed by the Open GeoSpatial Consortium.

It’s not difficult to appreciate the problem, REST based interfaces, KML, GeoJSON, GeoRSS etc might actually be the best technologies to use today and would be the tools of choice of many, however like many other Government IT projects INSPIRE needs to follow the low risk route of SOAP, WSDL, WMS, WFS etc.

So we may find that organisations will use OGC style interfaces to communicate to other public sector organisations and the commission, while using lighter weight technologies to publish information to their citizens. This is no bad thing !!

I am however disappointed by the continued focus on metadata driven catalogue services as the primary mechanism to find geospatial data, I don’t believe this will work as nobody likes creating metadata, and catalogue services are unproved.

INSPIRE needs GeoSearch !!

Google search extended to KML – Wake up everybody

It’s been a couple of weeks now since Google announced that its main search engine is now able to search and parse KML files, the native file format for Google Earth. This was widely reported in the blogosphere but with little comment, I’m not sure most mainstream GIS users are even aware of the news..

They should be !!

It might not seem a big deal, after-all KML is a “Google” format, and you would expect it to be searchable in the same way that a pdf document is for example. But.. and its a big but, the Google search engine is parsing and understanding the geographical data within the KML and returning relevant results geographically in additional to all the every clever page rank stuff.

KML Google search

So if I chose to publish the KML file of my evening walk around Teddington on my web-site.., The Google spiders would find it and parse the content noting from the description tags that it is about teddington, but would also get the extents of the GPS track from the linestring co-ordinates.

Now anybody searching for content on Teddington would find the file and its content either from the term teddington, or if using Google Earth from it’s actual location encoded as geographic co-ordinates.

Ok now move beyond a simple walking track to a KML with a linked shapefile, or network link to an enterprise spatial database of agricultural information. The mechanism described would search and find this content just as well !

As Michael Jones points out in the excellent Directions interview, Google Earth and I guess potentially tools that understand KML like ArcGIS Explorer become browsers of Geographic content in the same way Firefox or Safari are browsers of document based content.

What does these mean for the GI industry – I think this is really important !!

To develop infrastructures of Geographic information (SDI’s) we are doing the “right thing” working hard on metadata standards, and discovery portals but it is taking a long time and may need a revolution in semantic techniques to actually work using even quite broad controlled vocabularies of terms.

But hang on… the rest of the web did not wait to develop metadata standards for page content, instead it could be argued they took the “dirty” route and chucked massive computing power and very clever search algorithms to solve the problem with great success – To Google is now mainstream language.

With INSPIRE now real, it’s interesting to think, is the solution to a practical and cheap to implement SDI, publishing KML files and a simple search box ?

Wake up everybody !!!
