I just saw this article on Geocommunity. Apparently , a private company called Mapflow is teaming up with the Dublin Transportation Office (Ireland) to do a feasibility study on the use of satellite technology to track cars in real-time, and then charge drivers for the distance they travelled on the toll road. The study is also being funded by the European Space Agency. Yeah……. I think I will leave it at that, and let you read the article
I have read about it everywhere, I mentioned in the podcast, now it is time to blog it. Google Earth has included layers pointing to National Geographic information, primarily multimedia. Another reason to while away time playing with Google Earth.

During one of my “brain hurts” breaks tonight I came across this site. I came in originally through their map builder, which lets you create a map that shows the states you have visited. However, on closer inspection it is quite an interesting concept, kind of a travel guide wiki. The front page prompts you to 1) Find travel info, 2) Take it with you, and 3) Update it when you return.
In the September issue of GeoWorld, Daniel Sui has a short article discussing the notion of a humanistic GIScience and how geospatial technologies can play a broader role in defining and representing complexe realities

This is another in the line of UK sites we have pointed out this week. Voices maps recordings of interviews with British residents from England, Scotland, and Northern Ireland. Through these you can get a sense of the linguisitic and cultural differences as you move through the country. Some of the recordings include colorful langauge, but these should be marked.
This gives insight into the linguistic landscape of of the islands along with some cultural flair and aural and oral cartography.
Geosoft has added Shuttle Radar Topography Mission (SRTM) data to its public server. Elevation data for basically the whole world is available at 90 meter resolution and the US at 30 meter resolution. I checked out the site, and the data is in the public domain and free to download.
Here is the link to their data server
I have been waiting to get my hands on one before I blogged this. Clearly I have one, a demo unit from ShaperTechnology, and it lives up to its hype. This is a 800×600, 1600 Lumens DLP projector that can project active stereo images at 120 MHz. This means that when used in conjunction with a stereo capable graphics card and a pair of stereo glasses & emitter you perceive the view in 3D. Traditionally, this would require a large $60k projector or the use of 2 projectors but the DepthQ is a portable $4k projector.
How is this related to Geography? Both in my research and at work we use a significant amount of 2.5D (surface based) geovisualization. By viewing a scene in stereo it allows for a more immersive experience than the traditional 2D views. Any kind of stereo can give this perception, but active stereo is often considered the best for many situations. The other stereo options are passive stereo, 2 projectors with a polarized filter, and anaglyph stereo, generally the red and blue glasses.
So far we have just been using the standard stereo in ArcScene, but we will test it with a few other apps, but I think it is pretty cool.
