Google Earth and GI Science

I have just returned from the beautiful town of Girona in Spain, where I was speaking at the AGILE 2008 Conference, a meeting of the key Geographic Information research laboratories in Europe, which was expertly organised by SIGTE the GIS Lab at the University of Girona.

As is increasingly the case at conferences I attend, researchers are using both Google Maps and Google Earth as mechanisms to communicate their results in an appealing way. I hope to be able to highlight some interesting examples over the next few days, but there seems to be a clear pattern emerging where spatial analysis may be carried out using programs developed by researchers or by using powerful analytic tool sets like ArcGIS or ArcGIS Server, but presented using Google Earth.

The products of the research are often rendered via KML for display, but what is perhaps still missing in some cases is for the results to be really published, i.e. for the KML files to be posted on a web server somewhere along with details of the research for others to discover.

Interestingly there was very little discussion of the neo/paleo-geography debate, which is great, I hope we have moved onto to a position where the users of “professional” high end tools such as those produced by ESRI see a natural final publishing step of creating KML output of their work, certainly with the tools now available in the next version of ArcGIS and the OGC adoption of KML this should be simple one.

Of course as you would expect there are limitations with the current generation of virtual globes, Google Earth included, for some aspects of GI Science. Notably in more complex handling of temporal and sub surface features, and in cartographic output more functionality is needed.

Some of these limitations reflect the largely mass-market focus of Google Earth, but such feedback is always useful to hear, todays research requirement could well be tomorrows mass-market standard feature, and it is wise never to underestimate how sophisticated users may become.

Thoughts virgin media are crap

iPlayer comes to Virgin Media

iplayer

Good News, the wonderful BBC iPlayer is coming to users of Virgin Media’s cable TV service, let’s hope the flaky infrastructure of Virgin Media can cope with the demand.

This poses an interesting question does it not, on one hand the ISP’s like Virgin Media are upset that applications like the iplayer are hogging broadband capacity, while on the other hand the same content delivered to set top boxes using the same fundamental network is OK.

Maybe Virgin Media is behind Net Neutrality after-all…

GPS Thoughts

PND’s not dead yet..

Last Week saw TomTom announce a large drop in quarterly earnings , with sales of their iconic PND becoming more difficult, needing price reductions to keep sales moving.

Many are suggesting this is the natural evolution of the market, with saturation at a particular price point on one hand, while on the other, mobile phones with GPS are taking market share. I’m not sure I buy the mobile phone argument yet, for sure in the medium term converged mobile devices may make personal navigation devices obsolete, but I don’t think the current generation of mobile devices such as the N95 are there yet.

TomTom has a strong brand name and produce well designed products, (The Apple of GPS ?), maybe the issue is the more familar one of techncology adoption, are we seeing the chasm where early adopters have the devices, but mass-market users have not moved.

If your were to read some newspapers in the UK, you would believe that following the instructions of a “sat-nav” would a best lead you into a field, or at worse onto a railway line in front of a speeding express train.

These reports must have an impact on the buying behaviours of many mass-market consumers, but do they explain Tom Toms recent problem, or are there a group of potential consumers who still find the whole business too complicated and expensive for their needs ?

Is the PND yet to cross the chasm ?

Unlike my friend at lost in spatial, I don’t think this is related to an alien plot (Dr. Who viewers only reference).
