Description
From 2008 to 2014, the Historic Environment Division (HED) acquired LIDAR data to assist with the interpretation and protection of archaeological landscapes in Northern Ireland. This specific dataset was collected in 2012, covering approximately 130km2 across 39 sites, and is provided as digital surface or terrain models under an Open Government Licence. The data is made available by OpenDataNI.
Use Cases
Detecting subtle topographic traces of archaeological features based on the high-accuracy digital terrain model.
Creating 3D landscape models for heritage site management based on the dense point cloud data.
Analyzing landscape change and feature preservation by comparing digital surface and terrain models.
Strengths
Data collected over a six-year period (2008-2014), providing temporal depth.
Covers a total area of approximately 130km2 across 39 specific sites.
Laser scanning provides high vertical accuracy of 0.5cm and rapid pulse rates.
Limitations
Column-level documentation is absent; field semantics must be inferred after download.
Data is provided 'as is' and is not supported, which may affect usability.
Row count and file size are unknown, which may limit suitability assessment.
