Opening Up Sensor Data
The EU-funded Sensors Anywhere (SANY) program offers the technical means to allow the free exchange and use of environmental monitoring data regardless of its source. It supports OGC standards. Several pilots are underway tracking air, water and land, with final results to be shared at an event on Nov 19 in Linz, Austria.

Dutch to Tax Drivers Based on Driving Distance, Road Time using GPS
According to the Associated Press, the Netherlands will levy a tax based on the time spent driving in order to reduce congested highways. When the plan takes effect in 2012, a GPS monitoring system will track the distance, time, and place of drivers who will pay a few cents per kilometer. The tax replaces an annual road tax that amounts to approximately $900 per year for a mid-size car.

Podcast: DigitalGlobe IPO: Pushing Geospatial into IT?
This week DigitalGlobe joined the ranks of other companies that are publicly traded. Does this move and the related buzz help move geospatial technology into the realm of the broader information technology space? How should we see this change? Also: concerns about GeoEye-1 push that company's stock down.

TomTom Map Share Feedback Even Surprises Tele Atlas
This week, Tele Atlas (TA) announced the first release of their global street network that is augmented with data from TomTom Map Share, a service offered to users of TomTom portable navigation devices (PND) that allows them to independently report a variety of road network changes including impedences, new signage, etc. The feedback is sent to TA, a TomTom company, but as a consequence of collecting so much additional data, TA recognized that it was also capturing new road geometry not previously mapped.
Users of TomTom PNDs have the option of providing feedback in a few different ways. One is to manually indicate road blockages, for example, but another is to share certain bits of data such as speed and position. As it turns out,TomTom users were leaving their PNDs on even in areas where there was sparse or no road coverage such as certain regions of Eastern Europe. This feedback made it's way to TA database managers that are recognizing that new road segments were being added to the community contributed data. This new information allows the company to selectively dispatch crews to verify new road geometry and perhaps identify pockets of new users for additional marketing and advertising.
I spoke to Mr. Arnout Desmet while attending the Map World Forum conference in Hyderbad. Directions just recently interviewed Mr. Desmet when it was announced that TA had signed a agreement with the Survey of India (SOI) to incorporate SOI data into the TA road database. He also informed me about TA's historical speed profiles which are now being incorporated into traffic information. TA began collecting speed information in 2006 and now has a database of historical profiles in 5 minute increments for various times of day and now over months of time. Essentially, TomTom users are acting as probes on the street network collecting a vast amount of data that now equals twice the entire road network of Europe every 24 hours according to Mr. Desmet. He believes this is a unique service that TomTom provides to users.

Indian Ministry or Earth Science Focuses on Developing Tsunami Early Warning System
In an interview conducted with Dr. Shailesh Nayak, Secretary of the Ministry of Earth Science (Government of India), we discussed the use of GIS in developing a tsunami warning system that was begun shortly after the Indonesian tsunami in December 2004. India recognized a need for a rapid response system for tsunami warning. His department instituted a program to develop a three-part system using sensor systems to monitor tides, ocean bottom pressure recorders, and other coastal monitoring stations. He emphasized the need to acquire data in real-time. However, in order to enact a warning system that was accurate, there was a need to establish a huge database of tsunami models.
