This dataset is a complete coverage of mapped and digitized ice-marginal deglacial 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 into 9 sub-groups. Deglacial Landforms is one of the subgroups.The Deglacial Landforms data layer is comprised of the following geomorphological features: 1) Deltas; 2) Fans; 3) Glaciofluvial Terraces; 4) Hummocky Moraines; 5) Hummocky Sand and Gravels; 6) Kame Terraces; 7) Moraine Ridges.Data recorded on the map includes the location and outline of the following geomorphological features: 1) Deltas: - Complete coverage for all mapped and digitized locations of delta sediment bodies for Ireland including name of the landform, background data source and a reference to previous work completed on the feature. 2) Fans: - Complete coverage for all mapped and digitized fan features for Ireland including name of the landform and background data source. 3) Glaciofluvial Terraces: - Complete coverage for all mapped and digitized glaciofluvial terraces for Ireland including the the name of the river system they are associated with and background data source.4) Hummocky Moraines: - Complete coverage for all mapped and digitized hummocky moraine (non-stratified) features for Ireland including background data source and a reference to previous work completed on the feature. 5) Hummocky Sand and Gravels: - Complete coverage for all mapped and digitized hummocky sand and gravel features for Ireland including background data source. 6) Kame Terraces: - Complete coverage for all mapped and digitized locations of Kame Terraces including name of the landform, background data source and a reference to previous work completed on the feature.7) Moraine Ridges: - Complete coverage for all mapped and digitized locations of Moraine Ridges for Ireland including background data source.

Provenance information 1. Filenames: DEGLACIAL_LANDFORMS.shpDate (12/11/2013).Originator - Quaternary & Geotechnical Section, Geological Survey of Ireland. Nature of change/update to data. There is an ongoing programme of digitizing all archival Quaternary data held by the GSI. Methodology - The Deglacial Landform feature files have been compiled from a variety of sources, including academic papers, and the feature outlines were then drawn on OSi Colour Aerial Photography. Sources Used as input Data for the Change /update - Revision undertaken 12/09/2015.Separate feature layers - Deltas, Fans, Hummocky Moraines, Hummocky Sand and Gravels, Moraine Ridges, Glaciofluvial Terraces, Kame Terraces were merged by Cartography section to form new Deglacial Landform combined polygon feature class which is part of the ICE-MARGINAL LANDFORM group . Attribute updates, new symbolsets and metadata revision also undertaken.Scripts/tools used: - Build/Clean/Merge & topologise tools in ArcGIS.
