Digi Ireland & Road Atlas of Ireland
Digital versions of the favoured mapping of Ireland’s motorists at 1:210,000, 1:450,000 & 1:600,000 Scale Mapping
TThe 1:210,000, 1:450,000 and 1:600,000 all Ireland products (in association with Land & Property Services (LPS), formerly OSNI) are reproductions of our data as represented on the published paper versions of these products.
The 1:210,000 data supplied in tiled format as geo-referenced TIFF images or as a DWG in both Irish Grid (IG) and Irish Transverse Mercator (ITM). This data is revised approximately every 2-3 years. It represents Irelands up-to-date Road Network including 738 kms of motorway, toll areas, speed cameras and speed detection zones.
The 1: 450,000 & 1:600,000 maps are available as geo-referenced TIFF images in both IG and ITM.
Ideal for background within a GIS application, these small scale datasets will allow you to drill down through the different view scales to the large scale detail below.
The National Roads Authority (NRA) has a primary function, under the Roads Act 1993, ‘to secure the provision of a safe and efficient network of national roads’. For this purpose, it has overall responsibility for planning and supervision of construction and maintenance works on these roads.
The National Roads Authority makes extensive use of OSi digital mapping, orthophotography, wind and noise mapping and Lidar technology for the planning, construction and maintenance of Ireland’s national road infrastructure. OSi mapping is also utilized by the NRA for research and development, for the collection of traffic counts and analysis on a spatial basis, for the Road Weather Information System and for the sharing of information between the NRA and Local Authorities. OSi mapping is also employed for the allocation of resources by location – to lower costs and to create efficiencies.
