ODW leverages the power of Geographic Information Systems (GIS) using Esri’s ArcGIS® software suite. GIS enables ODW to better visualize and spatially analyze public drinking water data.
ODW has been able to use GIS to visualize data in novel ways on the web. Using Esri’s story map design, ODW has produced a map to visualize the distribution of water treatment processes employed in Virginia, such as chloramines and membrane filtration, and special source water categories such as groundwater under the influence of surface water (GUDI).
