This collection consists of extensive aerial photographs documenting western South Dakota, with particular focus on the Black Hills region. The images span various dates and locations, including Meade and Pennington counties, and were taken primarily during the summer and fall months. Many of the photographs were created by the U.S. Army Corps of Engineers and the U.S. Department of Agriculture, some as part of efforts to monitor environmental conditions such as mountain pine beetle infestations.

The collection includes individual and sequential image sets identified by flight lines, roll numbers, and dates. Several groups of photographs are infrared and color aerials, some annotated or indexed, and are organized by geographic location or agency designation. Accompanying materials include photographic indexes, flight maps, USDA parameters, and some duplicate negatives.

This collection documents the programs, activities, and outreach efforts of the Engineering Resource Center at South Dakota State University. Established in 1986, the Center supported research, education, and technology transfer through initiatives such as the Office of Remote Sensing, the South Dakota Space Grant Consortium, the South Dakota Local Transportation Assistance Program, the University/Industry Technology Service, and the Essential Networking and Training for Entrepreneurship (ENTRE) program. Materials include newsletters, brochures, reports, course and program descriptions, applications, technical documentation, correspondence, and photogrammetry images.

Significant content is derived from the Office of Remote Sensing, originally founded in 1969 as the Remote Sensing Institute, which used satellite imagery and GIS technologies to support natural resource management across South Dakota and beyond. Included are aerial thermography materials, technical reports, equipment documentation, stereoscopes, and extensive sets of photogrammetry and aerial images of locations such as Brookings, Big Bend Dam, Meriden, Missoula, and numerous unidentified areas.

The collection also contains documentation from NASA-affiliated Space Grant activities, particularly in the form of award announcements and outreach newsletters. Other series include information on local transportation engineering support, entrepreneurship training, and collaborations between SDSU and industry stakeholders across the state.

The Engineering Resource Center Records reflect SDSU’s leadership in applied engineering, remote sensing, transportation planning, and economic development during the late 20th century. They are particularly valuable for documenting the university’s role in NASA's Space Grant program, South Dakota's infrastructure planning, and the integration of satellite and aerial imaging in environmental monitoring. The collection also illustrates efforts to connect academic research with public service and private-sector needs through interdisciplinary collaboration.
