This geospatial dataset depicts the authoritative locations of road centerlines located on Department of Defense sites (installations, ranges, and training areas) worldwide. This dataset was created from source data provided by the active, guard, and reserve components of the Army, Navy, Air Force, Marine Corps, and Washington Headquarters Services headquarters, and was compiled by the Defense Installation Spatial Data Infrastructure (DISDI) Program, within the Office of the Assistant Secretary of Defense for Energy, Installations and Environment, Business Systems and Information Directorate. The road centerline is defined as the center of the roadway, measured from the edge of the paved surface. This dataset does not necessarily represent a comprehensive collection of all Department of Defense roads. In some cases, road centerlines are included which are outside DoD installations. This does not imply DoD interest or control of such roads; it is only an artifact of the data collection process.
