Other input datasets and extensive local Natural Resources Wales staff knowledge has been used to augment the core geometry to incorporate critical spatial detail and attribution, such as flow direction and path, not available from the OS mapping and to verify the accuracy of the centreline itself. Sections of DRN belonging to a particular waterbody have been merged together so that a defined waterbody is a single record within the dataset (rather than being made up of hundreds of records within the DRN). DRN attributes become obsolete at this point and waterbody specific attribution has been added. Therefore the geometry for the resulting waterbodies is taken from the DRN, but the attribution and number of records is very different. Not all sections of the DRN belong to defined waterbodies and the final WFD river waterbody dataset represents <20% of the online DRN.
