The following OSi data are available under the NMA:
Large Scale Data
Large Scale Data is OSi’s core database of Irish roads, rivers, buildings, natural features, man-made features and more. This detailed dataset is queryable and used to enhance analysis and decision making across all sectors including planning, legal, agricultural, construction and engineering.
Small Scale Data
Small Scale Data is a less detailed version (raster) of certain OSi data (e.g. Discovery Data, City Series, Town Maps) that is primarily used for display and visualisation purposes.
Discovery Data includes forestry, trails, waymarked walks and summit information, and can be integrated with handheld GPS units. It can be used simply as a cartographic backdrop, or it can be leveraged for tourist and leisure activities, such as organising a sporting event.
Boundary Data includes county boundaries, electoral divisions (EDs), townlands and small area boundaries. It’s a powerful for use in demographic analysis, particularly when used in conjunction with census data.
Historic Mapping is a series of highly detailed maps developed from large-scale surveys of Ireland conducted between 1829 and 1913. These maps are particularly relevant to genealogists, historians, and history enthusiasts. Digital versions (geo-referenced raster) are available under the NMA.
VFR Chart Scale 1:500,000
The Irish Aviation Authority visual flight rules (VFR) aeronautical chart edition 06, Scale 1:500,000, has been produced in both laminate and paper versions. The chart is intended for VFR navigation within the boundaries of the Shannon FIR.
VFR Chart Scale 1:250,000
The Irish Aviation Authority visual flight rules (VFR) aeronautical chart edition 003, (Scale 1:250,000), have been produced in both laminate and paper versions. The purchaser can buy either version but will get four charts on two sheets of paper covering the Shannon FIR in one plastic wallet. The chart is intended for VFR navigation within the boundaries of the Shannon FIR.
OSI supply a variety of products for use in representing height and ground relief. Available as Contour tiles, Digital Terrain Models and also LIDAR (Light Detection and Ranging) high accuracy datasets.
There are 250 tiles in the Contour and DTM series (Republic of Ireland). Additional tiles produced by Land & Property Services (formerly Ordnance Survey NI) are available for Northern Ireland. Each tile covers a ground area of 20km x 20km, and all are available in Irish Grid (IG) or ITM Irish Transverse Mercator (ITM) and in vector and raster formats.
Digital Series Ireland
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. The 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
Ortho rectified photographs are far more than just images taken from a satellite in space. Captured digitally orthophotography is corrected to allow for slopes and other distortions so that it corresponds exactly to large scale mapping, providing high levels of accuracy.
Detailed information on wind speeds, electricity transmission and distribution networks. Wind Maps provide detailed information on wind speeds, electricity transmission and distribution networks for specific locations around Ireland at national and county levels. Ireland has one of the greatest wind energy resources in Europe. The wind atlas can assist all those concerned with the wind planning process and is of great use to developers and policy makers alike. The Wind map is displayed using OSi mapping in conjunction with Wind Atlas information for the specific location selected. Wind speeds are displayed per meter / per second for onshore or off shore locations and are a valuable source of reference for wind farm developers.
