    Layer legends

     

    Every layer type has its own legend which you may request.  See GetCapabilities for the URL for the legend of interest. For example, this is the layer legend for radar:

    Coverage Area Considerations

     

    For several different reasons the layer you request may not return information for the entire globe:

    • Lightning is available by region, continent or the entire globe.
    • Layers may be specific to a certain country, region, or extent; see the Area column of the GetMap (layer) table.
    • The package purchase: if you’ve purchased a regional package, the geographic extent of the available weather returned by requests is dictated by that    subscription package.
      Example: The US/Canada package provides observations for the United States and Canada only.
