A spot height may be expressed as AOD for "above ordnance datum". Usually mean sea level (MSL) is used for the datum. Malin Ordnance Datum Derivation of vertical height or depth (in metres) In the Republic of Ireland, OD for the Ordnance Survey of Ireland is Malin Ordnance Datum: the Mean Sea Level (MSL) at Portmoor Pier, Malin Head, County Donegal, between 1960 and 1969. 5731 EPSG Projection 5731 - Malin Head height Metres Derivation of Altitude OD based on Mean Sea Level, Malin Head 1960-1969 Data provided for Ireland's Marine Atlas.

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
