NAVTEQ Map For Mexico Automotive Grade Quality Enhances GPS
Chicago IL (SPX) Jul 31, 2008 NAVTEQ has announced increased coverage and content in the NAVTEQ map for Mexico that enables improvements to the region's navigation systems functionality. The current map release includes almost 450,000 km of roads and covers the entire population. Twenty-three percent of that population is covered at NAVTEQ's highest quality levels: road network attribute verification, a specification distinctive to NAVTEQ maps. NAVTEQ collects up to 260 attributes about the road network, such as direction of travel (one-ways), turn restrictions, and addresses providing automotive grade maps for use in line-fit or portable navigation systems. Unique to NAVTEQ, all of their global maps are built to a single data specification with a standard toolkit that supports quality map collection and verification. Local geographic analysts familiar with regional nuances collect and verify the map content using a variety of processes including driving the roads. "Digital maps that support turn-by-turn vehicle guidance need to be highly accurate, and detailed," stated Eliot Dam, director of product marketing- Americas, NAVTEQ. "Many road attributes such as turn restrictions or other restricted maneuvers are more efficiently collected or verified via in-vehicle processes. Other elements such as small physical barriers can only be collected and verified by geographic analysts on the road." NAVTEQ has three local offices employing up to thirty geographic analysts. Much of the database production is done locally as well in the Leon production center. "Because all of our map collection, verification and production processes are standardized against a common database specification, customers can more quickly and easily integrate new quarterly coverage and content into their navigation systems," stated Jim Dineen director and general manager-Latin America, NAVTEQ. "As we add more content and broaden attribute verification, end-users can receive improved routing benefits through the system providers' map update programs." The NAVTEQ map for Mexico quarterly release program represents NAVTEQ's ongoing commitment to the region. In addition to the Mexico map, NAVTEQ's regional global coverage includes the United States, Canada, and South American coverage in Brazil and Argentina.

San Diego State University Improves MEMS Accelerometer Tunability
San Diego CA (SPX) Jul 16, 2008Researchers at San Diego State University have developed a new concept for improving MEMS accelerometer tunability. This method can increase wide-band tunability with ranges much larger than current practice, a significant improvement from the previously accepted 5-10%. |
