A picture is worth a thousand words ?

Not when it comes to Geographic Information I would argue…

Adena very well I think identified the massive interest in imagery demonstrated by the vendors at this years ESRI UC exhibition in her latest directions magazine editorial. Imagery is great as context to other types of spatial information, but on its own I believe it’s value is limited.

There are a lot of innovative ideas in this part of the geodata business driven both by the massive demand of the new generation of geographic exploration services from GYM and now ESRI, and from the fact that for much of North America there is no large scale topographic information otherwise available.

While technologies like Pictometry are interesting especially when combined with tools like SocketSet and OpenFlight to produce 3-D city models (thanks to John Allan and Rick Mort of BAE for the Southampton example above) , they can only provide contextual information which need expert human interpretation to generate true information let alone ‘Geospatial intelligence”

Using the example above, without access to other geographic information, can you tell.. where in the city are we ?, what is the name of the street in the foreground,? what is the address of the red building?, who “owns” this property ?

To answer these type of questions and indeed to really carry out any type of spatial analysis you need detailed feature based information and I would argue for a lot of analysis up to date information as-well.

So until more feature based information can be produced (it’s expensive !!) new tools like ArcGIS Server at 9.2 and the increasingly popular OGC WFS standard will be constrained..

Have we have invented the equivalent of the CD player, but are still producing 78-rpm mono gramophone records.

And a semantic Geoweb based on imagery.. forget it !!

Google Earth inspiration was Star Treks tricorder !!

I flew into Dubai this morning to attend the second Map Middle East Conference, and was knocked over by the presentation of Michael Jones CTO of the Google Earth/Map/Local team. Jones presented the vision for Google’s “geography” applications, which was breathtaking in its scope.

Building on the Google mission to organise the worlds data, Jones presented his mission to geographically organise the world data, that is all data – not just explicit geographical information.

What stuck me here, more than anything else, was the vision to present the context of geographical information rather than explicit information about locations, representing the sense of place – what does a place feel like, indeed the talk was entitled “A Sense of Place”. Geography here appears to be really important to Google – actually close you eyes and it might have been Jack Dangermond talking.

Indeed Jones cited “Father of GIS” Roger Tomlinson, who in the late 1960’s wrote of the ultimate GIS which would be a computer globe of interactive data, as an inspiration behind the development of Keyhole/Google Earth, another inspiration was Mr Spock’s Tricorder which could tell the science officer all the information he needed to describe his local environment.

With reference to the established GIS community Jones, perhaps mischievously, described Google Earth as the GIS for the 5.999999 billion people of the world’s 6 billion population who don’t know or care was GIS is.

To me it was quite a contrast to the other more traditional GIS vendors presentations, perhaps more than ESRI even, the Google Earth team seem to be driven by a very clear, user focused geographical vision.

Today’s business model for this may not be sustainable, but Google are building a massive user-base which will be difficult to displace, and the often forgotten professional and enterprise versions are gaining momentum in specific industries. When the current business model changes things will really get interesting !

And as many people at the conference mentioned, because of Google Earth, people at last know what we do !

Google Earth – A community GIS ?

Australian flying car project revealed

The latest Google Earth mystery to achieve fame has been reported by The Register , an apparent flying car spotted in Perth, Western Australia. What interests me most about this and the “black helicopter” spotting craze, is how these sightings rapidly travel around the community of Google Earth Users.

Perhaps we are all guilty of focusing too much of the neat globe user interface and unprecedented availability of data in Google Earth – in fact the thing which Google Earth may be remembered for is as the worlds first truly global community GIS, in which its long term value is making available really useful community derived data-sets.

After-all if you are like me, when I buy something now on Amazon, I always check the customers reviews – valuing this information at least as much as the manufacturers data.
