Archaeology & Heritage

LiDAR (Light Detection and Ranging) is an advanced active remote sensing technology that has transformed the way landscapes and built environments are mapped and analysed. The system operates by emitting laser pulses towards the ground and measuring the time taken for those pulses to return after reflecting off surfaces. Using the known speed of light, precise distance measurements are calculated, resulting in the generation of highly detailed three-dimensional datasets that accurately represent the surveyed environment.​

​

​Precision and Efficiency

LiDAR’s exceptional speed and accuracy enable the rapid, large-scale capture of detailed information across archaeological landscapes and heritage sites. The resulting high-resolution 3D data supports the accurate documentation of heritage assets and provides a valuable baseline for future conservation and restoration efforts.

Repeat LiDAR surveys also allow for ongoing monitoring, helping conservation professionals to identify subtle changes, degradation, or emerging risks before they develop into more significant issues.

​

Advanced Analysis

LiDAR surveys generate dense point clouds that represent the surface geometry of the surveyed area in high detail. These datasets can be used to produce accurate topographic plans and digital terrain models. When integrated with photogrammetry using measured control points, LiDAR data contributes to composite models that support detailed analysis, interpretation, and long-term documentation.

LiDAR also complements UAV imagery by providing precise elevation and terrain information. The integration of LiDAR and drone-derived datasets results in a more comprehensive and reliable representation of complex sites.

​

Comparative Studies

LiDAR enables direct comparison between historical and contemporary datasets, allowing changes over time to be identified and analysed. This is particularly valuable for understanding landscape development, exposure, erosion, or degradation within archaeological and heritage contexts.

​

Presentations and Visual Immersion

LiDAR-derived datasets can be used to create engaging visualisations and media presentations, enabling audiences to explore historic landscapes in detail. These outputs support education, interpretation, and public engagement by presenting complex spatial information in an accessible and compelling format.
