The service and discovery URLs provide basic information describing and listing the COVAR_SPAT data layer values that are available via the AKN web service. A layer list request returns the entire list of COVAR_SPAT and COVAR_FRAGSTAT attribute names. A metadata request returns a descriptive record for the requested attribute. Both the layer listing request and the metadata request will accept a format parameter that specifies a response data format of XML or CSV.
