Loudoun County distributes spatial data in ArcGIS coverage or shapefile format for the cost of reproduction. Countywide spatial datasets may be purchased for $21 per CD or $22 per DVD for up to 650 MB or 4.5 GB of data, respectively. There is a $10 surcharge to purchase countywide topography, and a $3 charge if the item is to be mailed. If the customer wants the data in DXF format and/or would like OMAGI to custom select specific geographic areas of the County, there is an additional $7 per 15 minute increment labor charge. Select aerial imagery is also available.

B_W_1937
United States Farm Service Agency (USDA FSA)
This data set contains the 1937 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 mosaicked by Loudoun County OMAGI to produce digital representations. This aerial imagery is at a much larger scale than the County's other Historical Raster image (1957). There are only 200 photos that cover Loudoun County for the 37 imagery, as opposed to 700 for the 57.
This aerial imagery project was coordinated by the Loudoun County OMAGI. The backdrop image was developed as a historical reference, and has potential for land use/land cover change research, environmental resource investigations, and other temporal change analysis.
