    Geo-referenced raster data for over 20,000 historical maps, in Northern Ireland, dating from 1835 to the 1960’s is available. These maps are of significant cultural and social value and provide a unique insight into our local heritage.

  • Raster Mapping

    Raster Mapping

    Raster maps are the simplest form of digital mapping, consisting of a digitally scanned version of a paper map which has been geo-referenced to its exact location. Maps are supplied in 1:250000, 1:50000 and 1:10000 scales with each map providing a greater degree of topographical detail.

  • Vector Mapping

    Vector Mapping

    Vector maps are a digital representation of topographic map features which can be manipulated with attributed points, lines and polygons. Vector maps are available in a range of data formats for use in a GIS. By combining these with other datasets you can greatly increase the functionality of any data you possess.

  • Orthophotography


    Orthophotographs are created from high quality aerial images, which provide a detailed bird’s eye view of the landscape. All photos are taken in optimal weather conditions and all distortions are rectified before the images are published.
