1957 - 1958 Aerial Imagery
B_W_1957
Loudoun County, VA, Office of Mapping and Geographic Information (OMAGI)
This data set contains the 1957 and 1958 aerial imagery for the majority of Loudoun County, VA. It is composed of United States Farm Service Agency (USDA FSA) hardcopy imagery, which were scanned, georeferenced, and mosaiced by Loudoun County OMAGI to produce digital representations. Individual images cover approximately 15000' by 15000'.
This aerial imagery project was coordinated by the Loudoun County OMAGI and the Loudoun County Department of Building and Development. The backdrop image was developed as a historical reference, and has potential for land use/land cover change research, environmental resource investigations, and other temporal change analysis.

1. Loudoun County scanned the contact prints using a HP scanjet 7400c. The images were scanned in grayscale to TIFF format at 600 dpi. 2. The digital image files were then georeferenced to the 2005 1' Panchromatic DO of the County. 3. The georeferenced files were mosaicked, using histogram matching techniques to correct color differences and improve the aesthetic quality of the data. 4. The mosaic is clipped according to a 50 foot buffer of the county. 5. The final mosaic is in TIFF format with an ESRI compatible world file.
Loudoun County obtained contact prints of the aerial photos flown by the United States Farm Service Agency in 1957 and 1958 that cover the county.
