Digital Weather Markup Language (DWML) is an XML-based format developed to support the exchange of the National Weather Service’s (NWS) National Digital Forecast Database (NDFD) data.
DWML contains current and forecast weather conditions for specific locations.
For more information on this format, visit the National Weather Service website at https://graphical.weather.gov/xml/.
Reader Overview
The DWML reader translates contents of a DWML file into features that contain weather conditions for a date and time at a specific location.
The coordinate system is fixed to LL84.
