Livermore Valley Winegrowers Association (LVMA) contracted with VESTRA to provide services in creating climate maps from the Prism Climate Groups data to assist LVMA with their effort to assess vineyard suitability within the Livermore Valley American Viticulture Area (AVA). The project consisted of migrating 30 years’ worth of climate data from the Prism Climate Group’s website into ArcGIS Online as feature services. Using these services, VESTRA built maps in ArcGIS Online using Web AppBuilder for ArcGIS to asses such things as annual average precipitation, average mean temperature per month, minimum/maximum temperature per month, and average growing degree days.
