The NPS is the lead federal agency assigned the principal responsibility for administering three federal historic documentation programs: the Historic American Buildings Survey (HABS), the Historic American Engineering Record (HAER), and the Historic American Landscape Survey (HALS). The documentation programs and their associated collections are among the largest and most heavily used in the Prints and Photographs Division of the Library of Congress. The collections document achievements in architecture, engineering, and design in the United States and its territories through a comprehensive range of building types and engineering technologies including examples as diverse as the Pueblo of Acoma to the Minuteman Intercontinental Ballistic Missile Launch Control Facility in South Dakota. Administered through cooperative agreements with the NPS, the Library of Congress, the American Institute of Architects, the American Society of Civil Engineers, and the American Society of Landscape Architects, these federal documentation programs have recorded America's built environment in multi-format surveys comprising more than 556,900 measured drawings, large-format photographs, and written histories for more than 38,600 historic structures and sites dating from Pre-Columbian times to the twentieth century. Through this agreement, the NPS , Intermountain Region, is seeking to work with a cooperator to expand the documentation of heritage sites to include: producing 3D high definition digital documentation of resources through LiDAR scanning, photogrammetry and other state-of-the-art technologies, including 3D point clouds, 3D visualizations, 3D models, 3D reconstructions, 3D virtual tours and 3D animated fly-throughs; training and employing students to produce 3D digital documentation; developing educational and interpretive content associated with the 3D digital images; creating virtual learning opportunities through web-based applications for research; archiving and managing digital data in accordance with National Archives and Records Administration (NARA) standards; providing free access to the data via a website designed for use by the general public; and hosting and maintaining that website.
