My apologies, I misspelled Episode 20 as ‘eposide’ in the file name generating a 404-file not found error. It is fixed on the site now and shouldn’t have impacted anything other than the direct download from the site…though it will still be Eposide20
British Telecomm wants to make sure your car doesn’t drive away without you…if you live in the UK. To this end they offer the BT Trackit system which, once installed, checks for a signal from an emitter you carry on you. If you and your signal are present, off you go. If your signal is absent then the location of your car is sent to the authorities and you are contacted with the lovely news that your car has wandered off without you.
Tim Warner mentioned this non-profit organization on this weeks episode and it looks quite exciting. In their own words, “SkyTruth promotes environmental awareness and protection with remote sensing and digital mapping technology.” They support environmental advocates, local planners and others through their remote sensing activities and have been doing so since 2002.
To learn more and to support their efforts check out their website at:
A recent editorial by Joe Francica at Directions Magazine discusses the impact of the “Google Phenomenon” on the geospatial software industry, and offers some interesting perspectives on how Google Maps and its competitors are already changing the business landscape and how traditional GIS and geospatial vendors must find a way to win the “struggle for relevance.”

Understanding how diseases spread is not a new discipline of study, but with increased concerns about the effects of our global world on the spread of dangerous viruses like SARS, AIDS, and yes, bird flu, I thought it would be timely to mention yet another use of GIS, Remote Sensing, and other geospatial technologies: landscape epidemiology. As a discipline, it dates back to the 1960s, when the notion that understanding the landscape and environment in areas where certain diseases develop or are particularly dangerous could help in predicting where diseases will spread and how severe outbreaks will be. Satellite imagery and GIS are being used successfully in landscape epidemiology studies, and a number of examples can be found on the Web, including a GIS project mapping SARS featured at GISUser.com
The ZevRoss website has a nice overview article here
A student in the UK has mapped the London Tube system using time as his base of measure, not distance. While his approach isn’t exactly novel, it is interesting, especially coming from a non GIS background.
The University of Maryland has an interesting concept for traffic monitoring and mapping – peer-to-peer traffic monitoring! The idea is that cars will be equpied with devices which can communicate with nearby cars to report traffic conditions and the like. It’s an interesting use of peer-to-peer technologies and potentially GIS.
