Abstract:
The Virginia Wine Board promotes the interests of vineyards and wineries in the commonwealth through research, education and marketing. In that spirit, the Wine Board partnered with Wise DEVELOP to map the extent of Virginia vineyards. Current vineyard monitoring practices require land surveys and reports from owners, and the vineyards are identified and mapped by their street addresses. High-resolution images were used to digitize the extent of all vineyards in Virginia. Vineyard extent was measured using data from Landsat 8 Operational Land Imager (OLI), which was downloaded from U.S. Geological Survey (USGS) Earth Explorer for the year 2014. Training sets were created from various locations across the state. A supervised classification was carried out using those training sets to identify the productive vineyards. Cropland data, obtained from the U.S. Department of Agriculture for the years 2008 to 2014, were stacked to identify the dominant type in the area. The results of this project will inform the Virginia Wine Board of the extent of the vineyards in its efforts to explore the possibilities of extension.
