Digital aerial photo mosaic covering much of the west side of the City of Green Bay created from scanned photos from year 1948. Hard copy photos were obtained from the City of Green Bay and scanned and digitally georeferenced using ArcGIS Pro in 2023 by Brown County Planning & Land Services Department interns. Black & White imagery. Scans were done in house at 600 dpi yielding a ground resolution of approximately 0.25 feet. The hard copy photos were large scale but the exact scale was not noted before returning the prints back to the city. To produce this dataset, individual 1948 photos were registered to common points on more recent orthophotos. This is not a true orthophoto; no DEM was used. Horizontal accuracy of the 1948 mosaic dataset varies but is generally less than 20 feet in most places.
