Dublin City Council Administrative Areas and City Boundary Dublin City is divided into 5 administrative areas that together form the boundary of Dublin City Council. These are called Local Areas and are used to co-ordinate the delivery of community services. Dublin City Council Local Area Offices provide information about services in that area, local councillors and other Council developments. These area boundaries were created after the Local Government Act, 2000 and are generally used in conjunction with the local electoral areas (LEAs) and Electoral Divisions (EDs). They are updated as changes are made to the electoral areas and were last revised in 2011.'The Central Area includes Cabra, Broadstone, North Wall, East Wall, Drumcondra, Ballybough, Phibsboro and the north city centre. The North Central area includes Kilbarrack, Raheny, Donaghamede, Coolock, Clontarf and Fairview. The North West Area includes Finglas, Ballymun, Glasnevin and Santry. The South Central Area includes Ballyfermot, Inchicore, Crumlin, Drimnagh, Walkinstown, The Liberties and the south west inner city. The South East Area includes Rathmines, Rathgar, Terenure, Ringsend, Irishtown, Pearse Street and the south east inner city. 'The city areas and boundary maps are created in CAD Microstation and the spatial projection is DGN (Design) format.

(Formally “District Electoral Divisions” (D.E.D.’s)) Under the 2001 Local Government Act, the names of Wards and the names of District Electoral Divisions are now changed to Electoral Divisions. There are 3,440 Electoral Divisions (EDs) which are the smallest legally defined administrative areas in the State. Electoral divisions are referred to by their established statutory names.Coordinate Reference System: Irish Transverse Mercator.This dataset is provided by Tailte Éireann

Road Source Noise Model The dataset contains the noise model results for the Dublin Region showing population exposure to sound from traffic sources. The noise maps show colour coded areas in Dublin based on sound levels in 5 bands. These increment in 5 decibels. The night time band starts at 50 decibels and the 24 hour band starts at 55 decibels. There are two categories of sound sources mapped all roads and major roads (roads with more than 3 million vehicle passages per year). Traffic volumes are averaged to an hourly traffic count over a typical 24 hour day. The supporting dataset Total Traffic Volumes and Road Centrelines for Dublin City is also published on Dublinked. Dublin City Council revised the first set of 2007 road source noise maps to produce the current maps for June 2012. The 2012 Revision of Noise Maps and Action Plans are available to download in kml format at http://www.dublincity.ie/WaterWasteEnvironment/NoiseMapsandActionPlans/Pages/default.aspx

Unified School Districts with district and trustee area boundaries, within the extent of Alameda County; boundaries have been updated to show changes for Oakland 2013 redistricting and new Dublin USD Trustee Areas in 2018. Boundaries represent voting districts (i.e., district designation for each address) and therefore may align with parcel boundaries in cases where parcels (and sometimes residences) are divided by the true city/district boundary.

The 1885 UK parliamentary constituencies for Ireland were re-created in 2017 as part of a conference paper delivered at the Southern Irish Loyalism in Context conference at Maynooth University. The intial map only included the territory of the Irish Free State and was created by Martin Charlton and Jack Kavanagh. The remaining six counties of Ulster were completed by Eoin McLaughlin in 2018-19, the combined result is a GIS map of all the parliamentary constituecies across the island of Ireland for the period 1885-1918. The map is available in both ESRI Shapefile format and as a GeoPackage (GPKG). The methodology for creating the constituencies is outlined in detail below.

Methodology

A map showing the outlines of the 1855 – 1918 Constituency boundaries can be found on page 401 of Parliamentary Elections in Ireland, 1801-1922 (Dublin, 1978) by Brian Walker. This forms the basis for the creation of a set of digital boundaries which can then be used in a GIS. The general workflow involves allocating an 1885 Constituency identifier to each of the 309 Electoral Divisions present in the boundaries made available for the 2011 Census of Population data release by CSO. The ED boundaries are available in ‘shapefile’ format (a de facto standard for spatial data transfer). Once a Constituency identifier has been given to each ED, the GIS operation known as ‘dissolve’ is used to remove the boundaries between EDs in the same Constituency. To begin with Walker’s map was scanned at 1200 dots per inch in JPEG form. A scanned map cannot be linked to other spatial data without undergoing a process known as georeferencing. The CSO boundaries are available with spatial coordinates in the Irish National Grid system. The goal of georeferencing is to produce a rectified version of the map together with a world file. Rectification refers to the process of recomputing the pixel positions in the scanned map so that they are oriented with the ING coordinate system; the world file contains the extent in both the east-west and north-south directions of each pixel (in metres) and the coordinates of the most north-westerly pixel in the rectified image.

Georeferencing involves the identification of Ground Control Points – these are locations on the scanned map for which the spatial coordinates in ING are known. The Georeferencing option in ArcGIS 10.4 makes this a reasonably pain free task. For this map 36 GCPs were required for a local spline transformation. The Redistribution of Seats Act 1885 provides the legal basis for the constituencies to be used for future elections in England, Wales, Scotland and Ireland. Part III of the Seventh Schedule of the Act defines the Constituencies in terms of Baronies, Parishes (and part Parishes) and Townlands for Ireland. Part III of the Sixth Schedule provides definitions for the Boroughs of Belfast and Dublin.

The CSO boundary collection also includes a shapefile of Barony boundaries. This makes it possible code a barony in two ways: (i) allocated completely to a Division or (ii) split between two Divisions. For the first type, the code is just the division name, and for the second the code includes both (or more) division names. Allocation of these names to the data in the ED shapefile is accomplished by a spatial join operation. Recoding the areas in the split Baronies is done interactively using the GIS software’s editing option. EDs or groups of EDs can be selected on the screen, and the correct Division code updated in the attribute table. There are a handful of cases where an ED is split between divisions, so a simple ‘majority’ rule was used for the allocation. As the maps are to be used at mainly for displaying data at the national level, a misallocation is unlikely to be noticed. The final set of boundaries was created using the dissolve operation mentioned earlier. There were a dozen ED that had initially escaped being allocated a code, but these were quickly updated. Similarly, a few of the EDs in the split divisions had been overlooked; again updating was painless. This meant that the dissolve had to be run a few more times before all the errors have been corrected.

For the Northern Ireland districts, a slightly different methodology was deployed which involved linking parishes and townlands along side baronies, using open data sources from the OSM Townlands.ie project and OpenData NI.

Local Electoral Area (LEA) boundaries for Dún Laoghaire-Rathdown County Council administrative area. Local Electoral Areas dataset generated from the ungeneralised 2019 OSi National Statutory Boundary dataset.

Municipal districts where created under the Local Government Reform Act of 2014 and are subdivisions of local authorities. Municipal districts are comprised of one or more Local Election Areas. Municipal districts are known as Borough Districts in Clonmel, Wexford, Drogheda and Sligo and Metropolitan Districts in Limerick and Waterford. Kilkenny is designated as the Municipal District of Kilkenny. The City councils of Dublin, Cork and Galway as well as Dún Laoghaire-Rathdown, Fingal, and South Dublin County Councils are not covered by Municipal districts. The current districts, with the exception of Cork, were defined in a series of Local Electoral Areas and Municipal District Orders (Statutory Instruments) in 2018. Municipal Districts for the County Cork are defined in the County of Cork Local Electoral Areas and Municipal Districts Order (S.I. No. 28/2019). There are currently 100 Municipal Districts.

A GIS based quantification of Ireland's freshwater salmon habitat asset to determine the habitat quantity (wetted river and lake surface areas) available to migratory salmonids. The purpose was to inform the further development of salmon stock recruitment models to provide high quality scientific advice to inform the sustainable management of salmon fisheries in Ireland. The identification of these rivers as Salmon, Sea Trout or other types of systems is still valid and has not changed since the 2003 report was published. It should be noted that rivers identified in 2003 as ‘Not considered a significant producer of migratory Salmonids’ or river segments identified as ‘Not utilised by Salmon’ may hold small populations of salmon and/or sea trout which are important in biodiversity terms.Please note that the wetted areas (riverine habitat (m²)) were revised in 2012 (McGinnity et al., 2012). This work built on the 2003 wetted area report (Mc Ginnity et al., 2003).McGinnity, P.,Gargan, P.,Roche, W., Mills, P. & McGarrigle, M. 2003.

City Centre Litter Bin Survey DCC. Published by Dublin City Council. Available under the license cc-by (CC-BY-4.0).Survey of location of street litter bins in Dublin City Centre; including the Central Business District and part of the South-East administrative area of the city. Survey of location of street litter bins in Dublin City Centre. This 2008 survey was carried out in the Central Business District and extended to include part of the South-East administrative area of the city. The Central Business District (CBD) was selected as it has a higher concentration of street bins in an area with a high concentration of commercial, office and public buildings. It also comprises 97% of the citys Business Improvement District (BIDS) area. The CBD comprises 5% of the area of the city within the City Boundary and with 1000 litter bins is estimated to have 22% of the citys litter bins. 'It was decided to link the survey to the administrative and constituency boundaries in the city; Street name, District Electoral Division (DED), Dublin City Council Administrative areas and Local Electoral Area (Committee). Each bin is assigned a 7 digit identity number. The first four digits are the published DED number which relates to the respective DED, and are therefore similar for all of the lines with a DED. Dublin City DED, LEA and DCC area maps are also available as open data. The last 3 digits are unique to the bin within its DED. 'There are a total of 30 items of information, including location and description. The location data, i.e. DED, will facilitate transfer of data between constituencies and Areas in the event of boundary changes. Information fields include bin type, advertising space, cigarette butt box, location description (footpath, residential, retail/shop, school, public building, park or other) and adjoining Local Authority (shared roads). Bins types for the survey were divided into six categories:'A. Grey Round and Curved Top'B. Grey Round and Curved Top'C. Blue Square Triangular Top'D. Blue Square'E. Black Round'F. Silver Round'G.
