2025 Oregon Wine Symposium | Putting Your Vineyard on the Map: Using Spatial Data to Improve Efficiency

Vineyard management often takes a one-size-fits-all approach because growers don’t have the right tools to detect and respond to differences across their vineyards – whether in soil conditions, vine health, or grape production. As resources like land, water, and labor become increasingly scarce, vineyard managers need smarter methods to maximize their efficiency. The key challenge has been measurement: How can growers identify where and how much variation exists within their vineyards? Without being able to measure and visualize these differences, it’s nearly impossible to manage them effectively.

The MyEV platform offers a possible solution. This mapping tool helps growers collect, analyze, and visualize data about different areas of their vineyard. Armed with this detailed information, they can adjust their farming practices – like irrigation or fertilization – based on the specific needs of each vineyard section. We’ll demonstrate MyEV’s practical benefits using a real-world case study showing how it can make vineyard operations more efficient.
