The 304 photos in this collection cover areas in the following Pennsylvania counties: Allegheny, Armstrong, Beaver, Butler, Indiana, Washington, and Westmoreland. The scale of the photos is 1:80,000 with a focal length of 153.034mm. These photos were taken by Keystone Aerial Surveys, Inc. for the Southwestern Pennsylvania Regional Planning Commission (SPRPC). This collection was given to the Donald W. Hamer Center for Maps and Geospatial Information by the PA Department of Conservation and Natural Resources, Bureau of Geological Survey Library. The photos were scanned at 800 dpi on an Epson Expression 11000 scanner by the Donald W. Hamer Center for Maps and Geospatial Information. </SPAN><SPAN>Historic aerial photograph tile indexes were generated by staff of the Donald W. Hamer Center for Maps and Geospatial Information in ESRI ArcGIS Pro. Each tile Index is based on the collection’s center point index. Photo tile size and rotation were estimated using sample georeferenced photos.</SPAN></P></DIV></DIV> |
