Our map data for North America is compiled, developed, and maintained by a dedicated team of GIS Engineers who continuously update the database with new roads, communities, and addresses.
We use numerous sources to obtain official information on bridge heights and clearances, load limits, weight limits and allowances, one-way road designations, left-hand and dangerous turn restrictions, urban road classifications, as well as hazmat, truck-restricted, truck-designated and truck-prohibited roads. Every vehicle and time-based toll cost in North America is sourced from the respective toll authorities.
For certain countries around the world, data is provided by HERE. If you need more information about map data, please contact us or call 800-377-6453, Ext. 1 for more information.
