\\n \\n The Idaho Historical Aerial Photographs are a collection of both \\noblique and vertical historic air photos ranging from 1927 to the 1940s.\\n Primarily taken by the Washington National Guard, sets of prints are \\nheld by offices within the Clearwater National Forest in Orofino, ID, \\nthe Moose Creek Ranger District at Fenn, ID, the Wallace Ranger \\nDistrict, and the Idaho Panhandle National Forests at Coeur d\\u2019Alene, ID.\\n These prints were digitized and put online by the University of Idaho \\nDigital Initiatives department starting in 1997 and up through 2011. \\nMany of these prints were returned to their respective owners, while two\\n copies of the scans saved on CD-ROMs are held by the U of I Library. \\nPrints may also have been held by the Potlatch Corporation in Lewiston, \\nID, from which archival materials have now been transferred to the U of I\\n Library Special Collections as the Potlatch Corporation Historical Archives and many other non-digitized aerial photos are also currently held in the U of I Map Room. Collection efforts were facilitated by Emeritus Librarian Dennis Baird.
\\n\\n\\n \\n This collection is a mix of oblique and vertical images, oblique \\nmeaning the photos were taken at an angle and vertical meaning photos \\ntaken straight down. Indexes were created to show flight lines or paths \\nand precise locations of each photo taken, while others are gathered \\ninto mosaics, or a composite image showing thumbnails of many adjacent \\nphotos.
\\n\\nAerial photography has existed for as long as people have had access \\nto aircraft, such as balloons or even kites, and photography or a means \\nof reproducing a view. Beyond the novelty of seeing your location from a\\n different perspective, aerial photography quickly became a valuable \\ntool for surveillance, cartography, and for documenting historical land \\nuse. Photographers found that by taking overlapping photos or many at \\ndifferent angles, the images could be combined to show depth and height \\nof landforms and the built environment.
\\n\\nAerial photography became a very useful tool for war efforts to show \\nenemy movements and defensive positions. Regionally, national guards \\nsuch as the 116th Observation Squadron (also known as the Photo \\nSection), 41st Division Aviation of the Washington National Guard, the \\nlikeliest group to have taken the photos in this collection, were \\nengaged in aerial photography for observation and reconnaissance during \\nWorld War 1. After the war, aerial photography turned invaluable for \\nstudying the landscape from viewing soil erosion, mapping rivers, \\nshowing forestation, and to supporting civil works planning, \\nconstruction and other improvement projects. New Deal programs during \\nthe Great Depression, such as the Grand Coulee Dam and irrigation \\nprojects along the Columbia River, were also documented by the 116th \\nsection. The buildup to the start of WWII put a halt to their civil \\nphotographic projects and the 116th joined federal active duty on \\nSeptember 16th, 1940.
\\n\\n
\\n \\n Aerial photographs have been taken by commercial as well as state and\\n national governmental sources, such as the U.S. Geological Service, \\nBureau of Land Management, National Park Service, and all branches of \\nthe military. Advances in geospatial technology have vastly improved the\\n amount of data that can be collected and interpreted through aerial \\nphotography.
