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 ESRI Shapefile 10.x Water Framework Directive Environmental Protection Agency Data Manager +353-53-9160600 +353-53-9160601 PO Box 3000 Johnstown Castle Estate Wexford Co.

Some local names were also applied from the EPA monitoring program stations list. This Lake Segments layer was used as the base geometry for the Lake Waterbodies polygons. A "System B" typology was found to be the most appropriate basis on which to define lake types in Ireland; twelve types have been identified using the factors alkalinity (surrogate for Geology), depth and size. Biological data from 60 high status lakes across several types and River Basin Districts were used to test that the selected hydromorphological types, derived from these factors, can be discriminated on a biological basis. A thirteenth type was identified to include a number of lakes at altitude >300m. Latitude and longitude were not considered to be significant factors determining the flora and fauna of Irish lakes. The typology and risk assessment of Irish lakes for Article 5 included all lakes greater than 0.5 km² and lakes less than 0.5 km² if they were located in protected areas (e.g. in Special Areas of Conservation, or if they were used for water abstraction for drinking purposes).

Spatial Accuracy: data mapped from a 1:50,000 scale source. Thematic Accuracy: Lake Waterbody attributes are based on type criteria originating from the WFD System B typology. Altitude data came from a 20m resolution DTM. Alkalinity categories came from Geological Survey Ireland source data.
