The Suitability Model for Growing Hops, www.loudoun.gov/hopsmap, combines soils, slope, and aspect to classify all land within the county, from the most suitable to growing hops to the least. Aspect refers to the direction a slope faces, which relates to the sun angle and amount of sunlight that reaches the ground.
Users can search for property by address or parcel identification number (PIN), click the map for a variety of additional information such as zoning or specific soil type, and calculate acreage or distance by using the measurement tool. There’s also an “info” button with links to other sites of interest, such as the Loudoun County Parcel Assessment Database and the Old Dominion Hops Cooperative.
The Virginia Cooperative Extension office in Loudoun and the Loudoun County Office of Mapping and Geographic Information collaborated on the tool, using data from a variety of resources, including ArcGIS Online, the online version of the Geographic Information System software Loudoun County has used since 1987.
