Abstract:

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.

Purpose:

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 The backdrop image was developed as a historical reference, and has potential for land use/land cover change research, environmental resource investigations, and other temporal change analysis.

Supplemental Information:

Data are stored in the corporate ArcSDE Geodatabase as a raster feature class. SDE geotabase imagery is available in the County's GIS, whereas copies of source files are provided for public distribution.

The coordinate system is Virginia State Plane (North), Zone 4501, datum NAD83 HARN.

Maintenance and Update Frequency:
