File naming

GML file naming

The file naming for the OS MasterMap Highways Network GML will be constructed as Highways_ProductName_FeatureType_SupplyType_NullorDelete_volumenumber.gml.gz, where:

  • Highways identifies that the GML is from the OS MasterMap Highways Network product family.

  • ProductName is the name of the product that is being supplied, for example, Roads.

  • FeatureType is the name of the feature type that is being supplied in the GML file, for example, Road Link.

  • SupplyType is the type of supply the GML is, for example, Full Supply or COU.

  • NullorDelete will not be present in any GML file names if the GML forms part of a Full Supply. If the GML forms part of a COU supply, then Delete will identify if the file contains all the features which need removing from the customer holding as a part of the COU application.

  • volumenumber will be the volume number for the file, which will be three digits, and the first volume will be 001.
