Physiographic Units

Physiographic maps are cartographic representations of the broad-scale physical landscape units of a region, and physiographic units consist of physical regions showing internal uniformity with respect to one or more environmental attributes, which are clearly differentiated from neighbouring regions.

The three tier classification scheme shows a number of hierarchical landscape divisions, different levels of which will be used by different end users depending on the level of detail required.

Quaternary Geomorphology

The Quaternary geology of Ireland – Geomorphology Map 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.

Quaternary Sediments

The Quaternary geology of Ireland – Sediments Map is a representation of the surficial geology of Ireland at a scale of 1 to 50,000. The map shows the sediments mapped within 1 metre of the surface which were laid down during the Quaternary, bedrock at or close to the surface water bodies or made ground. Quaternary sediments are categorised according to their genesis. The main types of sediment recognised are tills, (glacio)fluvio/lacustrine deposits, alluvium, lacustrine sediments and peat. Bedrock and karstified bedrock at or close to the surface are also mapped out as separate units.

All Ireland Quaternary Map 500k (scale 1:500.000)

Coordinate System: Irish Transverse Mercator / ITM.

This is a joint GSI-GSNI project. The All-Ireland Quaternary geology map at 1:500,000 scale is an amalgamation of Quaternary maps from Ireland and Northern Ireland. Soil geochemistry and radiometric data from the Tellus and Tellus Border projects were used to subdivide undifferentiated till deposits in Northern Ireland to match the till types mapped in Ireland.  Merging data sets was achieved by statistical distribution matching. Data from the two surveys and the relevant literature were compiled, homogenized and simplified to produce a seamless data set comprising sixteen sediment types, four geomorphological features and the location of key sites with dated sediments.

Quaternary 3D Model of Dublin

Coordinate System: Irish Transverse Mercator / ITM.

​The Quaternary 3D models of Dublin city is an interpretation of our 1:50,000 scale Quaternary maps, using a subset of the National Geotechnical Borehole Database. The software used was Subsurface Viewer.  More information is also available on the Land Mapping programme dedicated page.
