Smart mapping leader Esri has released a robust collection of web maps that display NOAA forecast streamflow data for the continental United States. Esri’s multiscale web map applications allow users to view forecast water flows in real time at high resolution. The maps weave NOAA’s recently released National Water Model data and Esri’s ArcGIS functionality to provide interactive views of current and future water system behaviors. These data-rich maps improve NOAA’s ability to meet the needs of emergency responders, reservoir operators, ecosystem professionals, and floodplain managers by providing detailed information that can anticipate flood and drought conditions. National Weather Service data populates the interactive maps with hourly updates and forecasts for up to 10 days. “We share a common vision for the value that high-resolution water prediction brings to the nation.” said Edward Clark, director, Geo-Intelligence Division, National Water Center, NOAA. www.esri.com.
