Don’t mess with the map !

Its interesting to observe the amount of concern, it appears, has been generated by the BBC TV decision to change how they display their weather maps.

Comments have focused on the use of brown rather than green to represent “Land” on the graphics, the use of animation rather than symbols to represent rain or snow events and the use of a perspective or globe view form of representation – something becoming increasing popular in mainstream GIS tools such as ESRI’s ArcGlobe.

What is most interesting is that none of this technology is new, and many other TV stations have been using interactive graphics for more than a decade, it appears that an organisation like the BBC will always draw more attention because it is so much part of everyday life – and you and I, the general public, really don’t like change.

This is something we at the Ordnance Survey recognise through bitter experience, you change the look of a national icon with great care – but you do have to make changes!

It is important to really exploit the potential on animation and interactive graphics to display complex information, and when used well, this technology has many advantages over static graphics, not least that it is possible to communicate more information in a short period of time.

Personally I’m a sucker for something new and quite like the new BBC graphics, but then I liked the ethnic tail designs British Airways tried a number of years back!

Nokia releases Sentient Computing app

Nokia this week released a mobile phone application that perhaps paves the way for other ‘Sentient Computing” applications. Sentient Computing uses location as the underlying framework to deliver user centric applications – the key here is that location information is implicit not explicit as in traditional LBS applications (there are no maps !!!).

Sentient Computing applications tend to work is personal space rather than the larger areas that LBS might work, so if your LBS application works over a number of city blocks the sentient app works within a building or a room.

Nokia’s application “sensor” is a “friend finder” which uses local bluetooth networks to allow users mobile’s to communicate to each other without direct user input, allowing your phone to send messages on your behalf to other phone users which meet criteria you set.

The requirements for data to power these applications is also clearly different to LBS, but no less important – early applications such as Sensor are restricted by not having geodata available to them – for example you might want to automatically turn off the application when you are at the office or on the train, but have it switch on when you are in a restaurant or club.

Sentient computing applications I believe will be far bigger a deal than LBS simply because of their ease of use, but their requirements for geodata means a whole new ball game.

Jabbering on about GML

Although we GI people are very keen on GML our own XML, we all realise that XML is making much bigger impacts in the wider IT world. One great example I have come across as a result of my recent upgrade to Tiger is XMPP the XML description used by Jabber, a cross-service instant messaging system.

As a mac guru my preferred IM client is iChat which uses the AOL instant messaging system AIM, or uses local ad-hoc IP networks – the rather naff named “bonjour” system. But most of my friends, relations and my wife use MSN Messenger network until now a closed system which needed its own advert filled client application. Not to mention all those people out there using ICQ, yahoo etc.

As of the Tiger release of MacOS X , iChat now supports the Jabber system as well which means it now supports most of the popular IM systems from one client. Jabber works by passing xml encoded messages between servers which translate between the various propitiatory systems in real time – so at last from iChat I can send messages to be wife who is using MSN Messenger – I can also see her status available or not, and even pass smileys !

So can you draw the obvious parallel? this is a fabulous example of how GML could potentially be used in the future geospatial web, moving amounts of geodata between different geographic information services in real time.

It is also interesting to note that Jabber developed as a open source project, not pushed by any of existing IM operators who quite liked their closed shops – another parallel ?

btw IM traffic between my wife and I is largely one way consisting of shopping lists – ah the joys of technology.

Balalaikas in Blackpool

Just listened to a great radio programme which talked about the Soviet Military efforts to map the UK in the Cold War. The BBC are streaming the programme here for the next week. The story was also picked up by The Times.

Here is an example of the type of mapping the Soviets produced for major cities, in this case a 1:10,000 map of Granton harbour in Edinburgh.

It seems that Blackpool Bus Station was a primary target !

Another case of technology indigestion ?

So Autodesk makes other acquisition to add to its GIS portfolio, in this case C-PLAN the Swiss developer of municipal applications built on Oracle Spatial. In my time at Autodesk C-PLAN were an excellent partner in the German speaking parts of Europe, with very good solutions using Autodesk Map and MapGuide linked to a single corporate repository in Oracle.
So what now happens with the other big Autodesk technology acquisition, the Autodesk Design Server which came with VISION purchase – a product with now very little visibility in the market.

Acquisitions of technology companies is seldom easy, and Autodesk has not had the best record in the past few years – who remembers Autodesk World ? the product of Automated Methods (Pty) ltd an acquisition of now 10 years ago.
Why is it so difficult – well for Autodesk I think the issue has been and may still be the focus on Autocad based solutions, particularly in the Autodesk partner channel which makes the marketing and successful exploitation of something “different” difficult. With an established portfolio of products, the introduction of a new ‘alien” technology needs careful management to achieve sucessful integration – a very simple question needs to be answered – WHERE DOES IT FIT ?

Autodesk is not alone in suffering from this technology indigestion, but I wish them better luck this time.

Anybody here know Oracle Spatial ?

We are running a number of large Oracle Spatial projects at Ordnance Survey, which are part of our major investment programme to update key elements of our back office systems for managing our geodata.

This week it appeared that one of our Oracle contractors was to be pulled off the project to work elsewhere (you get used to this working with vendor contractors) – now this guy has really detailed knowledge of how Oracle Spatial works at the database level – he is one of that rare breed an Oracle Spatial DBA.

Now we have fortunately a very good strategic relationship with Oracle and we were able to get them to change their mind and the guy is still with us – but there is a deeper underlying problem here – where do you find skilled people who understand Oracle Spatial ?

There is a massive skills shortage in this area, Oracle itself has limited resources, there are a few independent consultants with some knowledge at a architectural level, but we really need people who understand the unique nuts and bolts of partitioning a spatial database !

And don’t rely of these people coming out of universities very few MSc courses seem to have caught up with the fact that increasing GIS is a corporate database activity, not a cartography specialism, and few courses expose they students to spatial database technology.

This really has to change !

MacOS 10.4 Tiger first thoughts

MacOS 10.4 Tiger

Installed Tiger on my dual processor G5 at the weekend, fast simple upgrade from panther, took an hour or so including the time to create the “Spotlight” database. In many ways this is the key to the new OS – searching for a document really does work as you would hope, in fact within an hour I had stopped using the finder and just searched for stuff rather than navigating through disk volumes and folders.

My Powerbook will remain on Panther until Cisco can produce a new version of their VPN client however !!

Spot the vendor ?

Conference hotel

I have just returned from the Informed Solutions international conference held this year in Estepona, Spain. I presented an overview of the Ordnance Survey and a stab at the dynamics of the future Geodata market.

This was my first time at this conference and I must admit I was rather impressed by the format, a few industry figures, a few of Informed customers and a large proportion of Informed Solutions staff spent a couple of days discussing GI strategy, enabling technologies, organisational issues and successful case studies. What I think stood out was the lack of “hard sell” and the spirt of openess that resulted, I got the feeling that everybody there, was there, with the expectation to learn something!

More on Map Middle East

One of the recurring topics amongst the excellent programme at Map Middle East was the common issue of implementing spatial data infrastructures (SDI). This topic seems to come up in every geographic area at almost every scale from local to global – the common element always seems to be how do you prove the value of a infrastructure which delivers consistent geographical information to potential users.

I was very impressed by the presentation given by Zul Jiwani of Orion Technology who was instrumental in the development of the Qatar Centre for GIS, one of the most successful national GIS programmes if not the first SDI. He made the very valid point that to really gain political support the value of geodata to all potential users needs to be proved first.

SDI’s will never be established successfully if the geodata they provide is not valued to the same extent as other infrastructures, will the user complain to the same extent when they lose access to geodata as they would if they lost access to water or electricity supplies.

An interesting aside was a example of unconventional data capture . In the state of Qatar which was a the time establishing its address framework – people ordering take-away pizza received them paid for my the centre for GIS if they used their “new” address.

The power of the customer…

Peter Cochrane ex-CTO of BT, has a very interesting post in his blog this week at silicon.com. He makes the point which I have made a couple of times, that the customer is increasing in command of distruptive technology which will upset the current markets and displace the incumbent major supplier – This really is important stuff, markets can change very quickly in the modern post-internet world.

I quote below a article I wrote in the now departed GI News on this topic two years ago.

The Napsterisation of geographic information

While we cannot condone the violation of intellectual property rights promoted by the Napster music site, Napster (and now Apple’s new, legal iTunes music service) provides important lessons for understanding how new technologies and the Internet are changing consumer attitudes towards acquiring digital content.
The experience of the music industry may also apply to geographic information, argues Ed Parsons, chief technology officer for Ordnance Survey.

Do you remember the first album you bought, or perhaps the first compact disc? Like many of my friends, my first CD was Brothers in Arms by Dire Straits, which I think cost me £11.99 in 1985. I seem to remember it was one of the first really popular CD titles. The CD was seen as a great advance over the albums and cassettes of the time. With your CD player, you could listen to any song you liked, in any order. And of course there was the amazing sound quality of the guitar of Mark Knopfler, because we were dealing with digital data.
For the next 15 years or so we all accepted that digital music gave us better sound quality and greater flexibility of listening, and we all started buying CDs instead of albums and cassettes, in some cases replacing our entire collections with little shiny discs. But in many ways nothing had really changed. From the perspective of both the consumer and the industry it was business as usual. Consumers still bought albums, although now in CD format, and the record labels still signed up new acts, produced albums and then used their considerable sales and marketing departments to drive popular artists.

The day music changed forever

Then on 1 June 1999 the recording industry changed forever. American Shane Fanning, a student fresh out of Northeastern University, launched a new service on the web called Napster. It brought together two technologies: the ability of any computer user to digitise or ‘rip’ the contents of a CD into digital files using the mp3 format; and the development of ‘peer-to-peer’ computer networks that allowed users to share files on their computers with other users around the world via the Internet.
The impact of Napster, and its rapid downfall, are well known. Napster is recognised as having created an epidemic of music piracy and having depressed the profits of the major music companies so much that they took legal action to shut it down within a year. However, I believe Napster signalled a more fundamental change in the music industry, a change that I expect will affect many other industries including geographic information.

Being digital

Napster was of course about technology, but it was also an expression of the individual wishes of the customer. Napster users were just as interested in creating their own mix of songs on their own CDs as they were in getting free music. Napster users were really beginning to exploit the fact that music was now digital and could be easily transported between PCs and portable mp3 players, and could be managed, reorganised and catalogued with ease using cheap computers.
The music files themselves can now be ‘repurposed’ as alert sounds on computers or even as custom ring tones on mobile phones. Increasingly, users are manipulating the digital data to suit their own needs.
Napster brought about a massive shift in user expectations of how digital data can be used, a shift that will affect all types of digital information including GI. The piracy of music clearly could not continue, and a more sustainable business model for electronic distribution of music has emerged – but more of that later.
How have users’ expectations changed?

Buying a piece at a time
Users now, and increasingly in the future, will buy data by the piece, wanting to purchase only the information or product they need when they need it.
In the music industry there has been a long, ongoing debate over the sale of music by the track or by the album. The battle seems won now, with most online music stores offering track-by-track download. But not just music is being sold by the piece – Stephen King famously published his novel The Plant one chapter at a time, generating an estimated US$3 million.
Outside the media industry, other industries where intellectual property is sold or licensed can be seen following this route. In the near future one can predict economists selling one formula at time, meteorologists selling a weather forecast for a single location and so on.
From a GI perspective, we are already making progress towards this method of operation, selling discrete individual map objects or attributes rather than a whole map database. It will be a challenge for many data providers to develop practical pricing models, but they will not be able to ignore the trend. Customer demand will become unstoppable.

Trying before buying
In the same way that Napster introduced the concept of ‘trying’ music, by allowing users to download unknown music to sample, increasingly users of GI will want to test drive data before they buy it. Few of us would buy a car without a test drive, and the software industry is more commonly offering fully functional trial versions to potential buyers. To protect the vendor, a software trial may be limited – for example, an application may work for only 30 days.
However, for digital material such as films and maps, which might be used only once, limiting their use is more difficult. Here it will be necessary to provide samples rather than the whole product, but with enough information to enable users to decide whether they want to buy the product. It could be argued that some form of Digital Rights Management (DRM) should be used in these circumstances. So far, though, DRM has not been widely adopted because of a lack of practical standards and the considerable difficulties in implementing such systems within existing applications and processes.

Building DIY solutions
The CD you danced to on the eve of the millennium may well have been created or ‘burnt’ specifically for the event using a mix of mp3 files downloaded from Napster and other such services. Increasingly, with the widespread availability of portable mp3 players such as Apple’s iPod, music lovers are transferring music from CD directly into memory and never using the CD again. Instead, they are creating play lists that may combine music from different artists or genres to suit their mood. These play lists may then be burnt back onto CDs for use in the car, creating a completely new, individually designed product.
A more sophisticated use of digital content in the development of ‘new’ products comes from the open source movement. These are the developers and users of applications running the look and feel of their favourite programmes on the Linux operation system ‘re-skin’. They download new designs produced by other developers from dedicated websites.
The ultimate expression of this digital DIY phenomenon is in Japan, where users of NTT’s DoCoMo mobile Internet service can design a completely new user interface for their mobile phone by downloading small Java applications that control almost every aspect of the phone’s operation. This form of self-expression means that almost no two phones are alike.
The DIY approach is not unknown in the GI market. Many applications require the combining of tools and sometimes data from different vendors. Moving forward, this approach is likely to become the norm in line with emerging services such as the ‘Find’ function on mobile operator 3’s 3G service. This integrates topographic mapping from multiple suppliers with points of interest and other data.
Like the DoCoMo example, such services will become user driven. Brand and perceived value will drive the user’s choice of which components to connect together.
Clearly, for this approach to work in the GI market, we need much greater levels of interoperability between tools and between data or information products. Initiatives such as the Digital National Framework (DNF) and the work of organisations such as the Open GIS Consortium are vital.

Napster grows up

So where is the GI market heading if it follows the path of the music industry? The online music industry came of age almost four years to the month after Napster was launched. At the end of April this year, Apple Computer launched the iTunes Music Store – an online store carrying the catalogues of all the major record companies with music available to download, legally and for a fee, immediately. In the first two weeks of operation two million songs were downloaded. As Apple CEO Steve Jobs commented, ‘Response to the iTunes Music Store has been phenomenal – we’ve clearly hit a chord with users….’
For the GI industry, the main lesson of the Napster phenomenon is at the end of Jobs’ statement. The technology that Napster first exposed allowed users to get what they wanted. We must be sure that we also use technology to give our users what they want. The GI industry may, ultimately, have no choice.”
