Openness rating:

This dataset is a complete coverage of mapped and digitized ice-marginal deglacial landforms for Ireland. The datasets forms part of the GSI Quaternary Map series. 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. The “Deglacial Landforms” data layer is a polygon feature in an ESRI File Geodatabase supported by attribute identification and symbolized in ArcMap using the Quaternary master style file ( and a layer file (ICE-MARGINAL DEGLACIAL.lyr).

Provenance information 1. Filenames: DEGLACIAL_LANDFORMS.shp Date (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.
