OC 1940 BW Image Service

BY USING THIS WEBSITE OR THE CONTENT THEREIN, YOU AGREE TO THE TERMS OF USE. The 1940 Historic Orthoimagery was derived from traditional orthophotography taken of Oakland County, Michigan. Original film negatives were cleaned, scanned, and raster digital files were created as TIF images. It is not known how the orthorectification, conversion or reprojection processes took place. This mosaic was created from a series of tiles stored in ERDAS Imagine format (IMG) in a Michigan State Plane South NAD83 International Feet projected coordinate system. Some tiles were missing from the IMG files used to create this mosaic, and one tile (XR-1A-109) did not have its respective world file. Therefore, some small gaps are present within the final dataset. The initial scale of the orthophotography is not known.
