About the Project The Cornell Institute for Resource Information Sciences (IRIS) maintains a large and comprehensive collection of aerial photographs for New York State dating from 1936 through 1995. The archive numbers some 50,000 images that cover 48 counties, many counties of which have at least three years of historic sequence. The photographs are primarily black and white direct contact prints, and in hard copy form they measure from 7” x 9” to 9” x 9” in size; scales vary. Historic aerial photographs are valuable resources for landscape and land use analysis, assessment of environmental impacts, development projects and education.
