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 See gis.epa.ie for full details on data resource ESRI Shapefile 10.x Water Framework Directive Environmental Protection Agency +353-53-9160600 +353-53-9160601 PO Box 3000 Johnstown Castle Estate Wexford Co.

Each Hydrometric Area comprises a single large river basin, or a group of smaller ones, and neighbouring coastal areas. Each area was assigned a number from 01 to 40 beginning at the Foyle Catchment and proceeding in a clockwise direction (an exception to this general scheme is the catchment of the River Shannon and its tributaries which, because of its size, was divided into two hydrometric areas, 25 (Lower Shannon) and 26 (Upper Shannon)). The boundaries recorded in the hydrometric areas map were originally based on the hydrologic divisions shown on the 1958 Ordnance Survey Ireland (OSi) map - Rivers and their catchment basins. Digitisation was carried out in 1997 from the 1958 source (1:63,360). Attributes are the hydrometric area number (assigned by EPA) and area calculated from the polygons themselves and associated (I)RBD. Shared boundaries between hydrometric areas and (I)RBDs have been updated as a result of field verification processes. Hydrological errors still exist in HA boundaries not shared with (I)RBDs.
