Abstract:  Bedrock is the solid rock at or below the land surface. Over much of Ireland, the bedrock is covered by materials such as soil and gravel. The Bedrock map shows what the land surface of Ireland would be made up of if these materials were removed. As the bedrock is commonly covered, bedrock maps are an interpretation of the available data. Geologists map and record information on the composition and structure of rock outcrops (rock which can be seen on the land surface) and boreholes (a deep narrow round hole drilled in the ground). Areas are drawn on a map to show the distribution of rocks. To produce this dataset, the twenty one 1:100,000 paper maps covering Ireland were digitised and borders and overlaps between map sheets were removed. We collect new data to update our map and also use data made available from other sources. This map is to the scale 1:100,000. This means it should be viewed at that scale. When printed at that scale 1cm on the map relates to a distance of 1km.It is a vector dataset. Vector data portray the world using points, lines, and polygons (areas).The bedrock data is shown as polygons. Each polygon holds information on the rock unit name, its description, stratigraphy code (rock layers with age profile), lithology code (rock type) and map sheet number. Each polygon is linked to the bedrock lexicon table which has more detailed information such as a definition of the rock unit, rock types, age, thickness and other comments.

Purpose: Knowing the structure and type of bedrock is vital in many areas of our lives. Bedrock maps help us locate groundwater sources which can be used to supply drinking water. Rock properties and structures such as faults impact how water and/or pollutants move below the surface. Drinking water can be protected by locating potential polluting operations, such as landfills, away from groundwater. Geothermal energy is the energy stored in the form of heat beneath the surface of the earth. It can be used to supply heat and hot water. It can also be used to cool a house by removing surplus heat energy and putting it into the ground. Bedrock maps along with subsoil and aquifer maps are used to help decide if the ground under a site is suitable for geothermal energy extraction. Engineers need this information when they are designing structures (houses, buildings, roads, etc.). They need to know the quality of the ground (strength and depth of soil, if rock and or groundwater is present) and how structures can be built in and on it. They use the information to decide the best supports and foundations needed for structures so that they don’t collapse. They can also find out if there are any underground obstructions, groundwater, faults etc which could result in additional costs or delays. Bedrock maps are used to find sites suitable for the extraction of valuable mineral deposits. Nearly all of the metals we use today are extracted from a number of minerals that different rocks are made up of.

Lineage:
Lineage statement: Geologists map and record information on the composition and structure of rock outcrops (rock which can be seen on the land surface) and boreholes (a deep narrow round hole drilled in the ground). Areas are drawn on a map to show the distribution of rocks. Originally, the bedrock was hand drawn on paper maps. All map sheets (21) are available in paper copy accompanied by a geological report. Phase 1: The 21 paper maps covering Ireland were digitised. Each map was manually digitised using AutoCAD 12.0 software. Several layers of data were created for each map sheet: Stratigraphy, Lithology, Igneous, Diagenetic, Dynamic, Thermal, Linework and Point symbols and stored in .dwg format. The data was registered to the OSi 1:100,000 digital rasters. The data was clipped to the OSi coastline (high water mark). Water bodies such as lakes were also clipped. Irish National Grid (IG) projection. Phase 2: Data was converted to ArcInfo coverages (1994-2003) IG AutoCAD layers were converted to .dxf format and imported into ArcInfo 7.x. Coding was used to attach attribute information to the data layers from the bedrock lexicon table. A legend was generated. The ArcInfo coverages were converted to shapefiles. Phase 3: Borders and overlaps between map sheets were removed. IG. ArcGIS 8.x and Microsoft Access were used. Access was used to join additional attributes to the data layers including a unique code called NEWCODE. ArcGIS 8.x was used to manually remove borders and overlaps and to fill gaps. Work was carried out by GIS staff in close collaboration with bedrock geologists. The final product was quality checked by bedrock geologists. A stylefile was generated. Shapefiles produced were: 1) Final100kunion.shp - A polygon shapefile that contains bedrock geological information on Stratigraphy, Igneous, Lithology and Diagentic codes, their unit names and descriptions, 2) Index100Map.shp – A polygon index of 1:100,000 scale map sheets to allow sheet number identification at 100,000 scale. 3) Final100kstruc.shp (Structural Linework) - A line shapefile that contains structural geological linework codes and descriptions. 4) Final100kstra.shp (Stratigraphic Linework) - A line shapefile that contains stratigraphic geological line codes and descriptions. 5) Cross100ksection (Cross sections) - A line shapefile that contains map sheet cross sections as per paper printed maps and provides links to the cross sections in image format. 6) Final100kmin.shp - A point shapefile containing selected mineral and quarry descriptions from Bedrock 1:100,000 map series. Phase 4: Bedrock 1:100,000 Map 2016 ITM New data was compiled and interpreted from the following sources: Tellus geophysics data (magnetic, electromagnetic, radiometric data), Tellus geochemistry data, borehole data and micropaleontology analysis. Higher resolution maps (1:50,000) were generated from the new data. When this information changes the distribution of the areas of rock, we update this 1:100,000 map with the changes. New data has been added into this dataset from sheets 28A, 77 and parts of Dublin and Galway. The data for Sheets 28A and 77 were produced as part of a 1:50,000 project and the Dublin and Galway data were produced as part of the GeoUrban project. Bedrock Map re-projected in ArcGIS from Irish National Grid (IG) to Irish transverse Mercator (ITM) projection. Updated the Irish coastline (ITM): geology filled in water bodies and locating and amending discrepancies between paper maps and digital version. Bedrock aquifer categories were added. Stylefile updated. Data topology checked. The dataset comprises 4 shapefiles. 1) Bedrock_Polygons_ITM_2016.shp - A polygon shapefile that contains bedrock geological information on Stratigraphy, Igneous, Lithology and Diagentic codes, their unit names and descriptions. It also contains Bedrock aquifer categories. It is linked to the bedrock lexicon table which has more detailed information such as descriptions of the stratigraphy, lithology, rock types, age, thickness and other comments. 2) Geological_Linework_100k_2016.shp - A line shapefile that contains structural geological linework codes, stratigraphic geological line codes and descriptions and cross section . It is linked to the bedrock lexicon table which has more detailed information such as descriptions of the stratigraphy, lithology, rock types, age, thickness and other comments. 3) Struct_Symbols_100K_ITM_2016.shp - a point shapefile that contains all symbols and dip labels from the 1:100,000 paper map series. 4) Bedrock_Outcrop_ITM_2016.shp - A polygon shapefile that shows rock outcrops. Phase 5: Bedrock 1:100,000 2018 ITM. New data was compiled and interpreted from the following sources: Tellus geophysics data (magnetic, electromagnetic, radiometric data), Tellus geochemistry data, borehole data and micropaleontology analysis. Higher resolution maps (1:50,000) were generated from the new data. When this information changes the distribution of the areas of rock, we update this 1:100,000 map with the changes. New data has been added into this dataset from sheets 24, 26, 27.1,28.1 32, 33, 34, 35, 39 and 40 corresponding to the counties of Sligo, Mayo, Roscommon, Galway, Leitrim, Cavan, Louth, Meath, Monaghan and Longford. Errors noted and recorded in the previous version were corrected. Data topology checked. The dataset comprises 4 shapefiles. 1) Bedrock_Polygons_ITM_2018.shp .- A polygon shapefile that contains bedrock geological information on Stratigraphy, Igneous, Lithology and Diagentic codes, their unit names and descriptions. It also contains Bedrock aquifer categories.
