NCHRP Report 676: Intelligent Soil Compaction Systems

TRB’s National Cooperative Highway Research Program (NCHRP) Report 676: Intelligent Soil Compaction Systems explores intelligent compaction, a new method of achieving and documenting compaction requirements. Intelligent compaction uses continuous compaction-roller vibration monitoring to assess mechanistic soil properties, continuous modification/adaptation of roller vibration amplitude and frequency to ensure optimum compaction, and full-time monitoring by an integrated global positioning system to provide a complete GPS-based record of the compacted area.

Digital Mapping Duopoly

January 15, 2008 rockman Miscellaneous Comments Off on Digital Mapping Duopoly

By way of Geology.com, the Wall Street Journal reports on some interesting news related to GPS and even our beloved Google Maps / Google Earth. Apparently there are only two games in town when it comes to data providers for online and digital mapping products that are used by the aformentioned software as well as your GPS navigation system: Netherlands-based Tele Atlas NV, and Chicago-based Navteq Corp.

In October, Nokia bought Navteq for …wait for it… $8.1 billion. They plan to use the technology as the basis for a business model involving selling advertising tied to your phone’s location. A month later TomTom, a maker of GPS products, beat out rival Garmin and bought Tele Atlas for $4.2 billion. Were either of these companies really worth that much money? It doesn’t appear like it. Thus concern has been raised that the new owners of the technology might be in a position to hurt competitors by raising prices. We will have to see how things pan out.
