Provenance information Digitisation carried out in 1997 from a 1958 source Data Data Capture:Boundaries shown on 1958 Ordnance Survey map were redrawn onto the Ordnance Survey 1/2 inch maps using map overlays, which were subsequently digitised using a digitising tablet. Thematic Accuracy:Only catchment code and area/perimeter values assigned. Spatial Accuracy:Shared boundaries between catchment areas and (I)RBDs have been updated as a result of field verification processes. Hydrological errors still exist in catchment boundaries not shared with (I)RBDs. Logical Consistency:Project to verify RBD boundaries in the field show the boundaries are not always hydrologically correct. It is Recommended that field verification be undertaken to verify internal catchment boundaries. Sources Used:Rivers and their catchment basins, OSI 1958 Discovery Series, OSI 1/2inch maps
