This dataset is a complete coverage of mapped and digitized ice-marginal meltwater landforms for Ireland.

This dataset forms part of the Quaternary geology of Ireland – Geomorphology Map which is a representation of Irish glacial geomorphological features at a scale of 1 to 50,000. The map shows categorised erratic carriage sources and sinks, subglacial lineations and striae, subglacial moraines, ice-marginal landforms and mountain glaciation corries and trimlines.

The Geomorphology dataset originally comprised individual feature layers that were subsequently merged from 25 single feature layers to 9 sub-groups, Meltwater Landforms is one of these subgroups. The Meltwater Landform data layer comprises the following geomorphological features: 1) Esker Ridge, 2) Meltwater Channels. Data recorded on the map includes the location and outline of the following geomorphological features: 1) Esker Ridge: - Complete coverage for all mapped and digitized locations of eskerbodies for Republic of Ireland including name of the landform, background data source and classification on the feature.The esker features have been compiled from a variety of sources, including academic papers, and the feature outlines were then drawn on OSi Colour Aerial Photography. An Esker is a long, winding ridge of stratified sand and gravel. Eskers are frequently several kilometres long and, because of their peculiar uniform shape, are somewhat like railway embankment.2) Meltwater Channels: - Complete coverage for all mapped and digitized meltwater features for Republic of Ireland including name of the landform and background data source. The map forms part of the GSI Quaternary Map series. Data recorded on the map includes the locations of meltwater channels, as well as attribute fields such as data source and channel length.
