Geographic Data Technology, which provides map databases for popular trucking mapping products, announced the new quarterly release of its Dynamap street and address databases.

The new databases include enhanced information for the nation's 600,000 miles of highway, new street and address information, and increased positional accuracy.
For the 600,000 miles of major highways, GDT has verified elevation information, connectivity and name consistency.
The newest versions of GDT's Dynamap products include nearly 18,000 miles of new streets. With these additions, GDT data products provide coverage for 6.9 million miles of streets throughout the U.S. and Canada.
Along with improved street and address coverage, the new database releases include enhanced and verified positional accuracy for 1.4 million miles of roadway representing 61 percent of the U.S. population. Repeated tests using the most current and reliable standard for measuring spatial data accuracy consistently show that GDT's realignment efforts achieve 7 to 10 meter accuracy, usually exceeding the 12-meter accuracy levels of other commercial databases.
