Monument Type: Multiple
Brú Na Bóinne is about 8km inland from Drogheda and describes an area between the towns of Slane and Drogheda where the River Boyne meanders into a dramatic loop or bend. Brú na Bóinne – the abode of the Boyne – is the name given to one of the world’s most important archaeological landscapes, dominated by the spectacular prehistoric passage tombs of Newgrange, Knowth and Dowth.
In recognition of the international importance of these monuments and the many other archaeological features in the area, the United Nations Educational, Scientific, and Cultural Organisation (UNESCO) has designated the Brú Na Bóinne area a World Heritage Site. Sites selected for World Heritage listing are deemed to be of outstanding universal value to humanity and are approved on the basis of their merits as the best possible examples of cultural or natural heritage.
Today at Brú Na Bóinne the remains of about forty mounds which are the oldest surviving traces of human activity in the area can be seen. They remained the focus for activity and tradition long after their formal use as burial places ended.
The passage tombs and associated monuments are in the care of the Office of Public Works.
3D Capture Method: Aerial Lidar
3D Capture Description: The Optech ALTM 3100 has high scanning frequency of 100,000 Hz to allow the collection of both high-resolution data for detailed surveys and highly efficient collection of lower resolution data for broad scale flood plain mapping.
The ALTM 3100 instrument is mounted on a fixed wing platform leased 365 days per year by the Agency as it forms the core mapping work undertaken. This system will be used for the proposed contract. LIDAR data will be collected at an altitude of approximately 900m, which with a scan angle of +/- 20º will result in a swath of 750m. LIDAR data will be collected at a density of approximately 1m resolution or one point per square metre
LIDAR data has a vertical RMSE of 15cm or better. The manufacturer's quoted accuracy of the ALTM LIDAR system is +/- 15cm in z.
Resulting data sets include first return (DSM) and last return point (DTM, bare earth) models
