    <abstract lang="eng" displayLabel="Abstract">This polygon shapefile depicts sites that were selected from the 2010 Base Structure Report (BSR), a summary of the DoD Real Property Inventory (RPI). RPI data describe land as well as facilities&#x2014;buildings, structures and linear structures such as utilities, roads and fences&#x2014;that the federal government owns, and for which DoD is accountable. This list does not necessarily represent a comprehensive collection of all DoD facilities, and only those in the fifty United States and United States Territories were considered for inclusion. For inventory purposes, installations are comprised of sites, where a site is defined as a specific geographic location of federally owned or managed land and is assigned to military installation. DoD installations are commonly referred to as a base, camp, post, station, yard, center, homeport facility for any ship, or other activity under the jurisdiction, custody, control of the DoD. This layer is part of the 2014 National Transportation Atlas Database.</abstract>
    <abstract lang="eng" displayLabel="Purpose">The National Transportation Atlas Databases 2014 (NTAD2014) is a set of nationwide geographic datasets of transportation facilities, transportation networks, associated infrastructure and other political and administrative entities. These datasets include spatial information for transportation modal networks and intermodal terminals, as well as the re&#xAC;lated attribute information for these features. This data supports research, analysis, and decision-making across all transportation modes. It is most useful at the national level, but has major applications at regional, state and local scales throughout the transportation community. The data used to compile NTAD2014 was provided by our partners within the United States Department of Transportation (USDOT) and by other agencies throughout the United States Federal Government. These contributors are the actual data stewards and are ultimately responsible for the maintenance and accuracy of their data. The dataset depicts the authoritative boundaries of the most commonly known Department of Defense (DoD) sites, installations, ranges, and training areas in the United States and Territories. These sites encompass land which is federally owned or otherwise managed. This dataset was created from source data provided by the four Military Service Component headquarters and was compiled by the Defense Installation Spatial Data Infrastructure (DISDI) Program within the Office of the Deputy Under Secretary of Defense for Installations and Environment, Business Enterprise Integration Directorate.</abstract>
