The Defense Table of Official Distances (DTOD) is the official source for worldwide distance information used by the Department of Defense (DoD). DTOD provides vehicular land distances for all DoD personal property, all DoD freight, and PCS/TDY travel needs. It generates point-to-point distances and routes for origin/destination pairs of locations. The DTOD website’s distance calculation and mapping functions provide road segment and cumulative distances over the network of truck-usable highways and roads in North America, South America, Europe, Africa, Oceania, and Asia.
You must have an approved DoD DTOD account, managed by SDDC's Electronic Transportation Acquisition (ETA), to calculate distances and view maps and directions.
