Mapping America’s Wine Growing Regions

Wine Country

Have you ever wondered where your wine comes from? Did you know that there are hundreds of distinct wine regions in the United States? Since 2017, Blue Raster has been working with the Alcohol and Tobacco Tax and Trade Bureau (TTB) to map over 270 of America’s Viticultural Areas (AVA) in GIS. Blue Raster then developed the AVA Map Explorer, a web mapping application to view, compare and download AVA boundaries.

Viticultural areas are designated grape-growing regions with distinguishable geographic features with boundaries defined by TTB. TTB is part of the U.S. Treasury and overseas regulation and tax collection on the sales of alcohol and tobacco. A map library with thousands of marked-up USGS topographic maps to written boundary instructions called the Code of Federal Regulations (CFR) at 27 CFR Part 9 is the official record and only way to view an AVA.

Example of CFR entry.

Working with SJ Technologies, the team started the conversion from paper to GIS by creating points for each CFR description in a Viticultural Area. Then, using industry-accepted national datasets including U.S. Census administrative boundaries and roads, and USGS contours and the National Hydrography Dataset, the connected CFR points form viticultural boundaries.

Larger viticultural areas may be drawn on over forty separate paper maps in the maps library. In digital format the number of paper maps is no longer an issue. The new approach allowed for the team to provide an extremely detailed product to TTB that was easily consumable. The ability to zoom in on complex areas or view an entire viticultural area on one screen had previously been impossible.

AVAs boundaries can be extremely detailed, but might not seem so when viewing at the full extent.

AVA Map Explorer

With over 270 AVAs mapped, Blue Raster developed the AVA Map Explorer. This easy to use application helps TTB staff with wine labeling, vineyards petitioning for inclusion in an existing or proposed AVA, and the public to learn more about where their wine comes from. Additionally, users can search AVAs by name, address, State and County filters, or simply by panning around and exploring. Because many AVAs have overlapping boundaries, the ability to compare AVAs was critical. Contained within a popup is information about overlapping AVAs, effective dates, and geographic extent. From the popup users can also link to the CFR, which is still the official record, view the public docket of petitions and rulings, and download the shapefile of the AVA.

More than just Napa and Sonoma counties in California, wine growing regions exist all across the United States.

In places with heavy overlap, it’s possible to add AVA's to a list to compare boundaries.

ArcGIS Solutions for Emergency Management Workshop

Emergency Managment Disaster Response training

Both man-made hazards and natural disasters significantly impact populations across the globe. Advanced preparation is becoming more critical than ever, especially within the government entities that manage crisis response and emergency management. To answer this demand, Esri has organized a new category of out-of-the-box toolsets designed to mitigate the risk of hazards and delegate resources in the wake of disasters.

ArcGIS Solutions for Emergency Management encompasses a range of products that help emergency management officials to manage response resources and visualize events as they occur across time and space. Earlier this month, the Blue Raster team attended a workshop on this program set at Esri’s Redlands Campus in Southern California. This event focused heavily on the Emergency Management Operations Gallery group, which features seven applications with seven unique maps and 33 total feature layers.

Our team gained significant experience with each of the applications, from configuration to deployment. We were particularly impressed by the cross-component integration and real-time feature updates. Once properly configured, this toolset features an extremely user-friendly interface with numerous options for customization of outputs and data visualization. Furthermore, one-click data inputs and feature updates result in fast and efficient communication of changing conditions.
