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.

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.

Creating a Sustainable Lens…a Digital Globe: Remote Sensing CEO’s Offer Future Vision

Two remote sensing technology CEOs offered provocative insights into how they will conduct their companies in the near future at the Map World Forum in Hyderabad, India today. Jill Smith of DigitalGlobe wants her company to proactively collect imagery of regions of the world where climate change or other problems might be of interest to the global geospatial community. Dr. Robert Moses of PCI Geomatics believes that one day we will use a web service to query and analyze for change detection in a region using not only a time-series of remotely-sensed imagery but advanced classification algorithms to automatically map and highlight the affected areas. "The greatest opportunity is to enable a true model using all of the available sensors," said Moses.
