Applications of LIDAR in Archaeology: Revealing Forgotten Landscapes

LIDAR (LIght Detection and Ranging) technology has transformed the field of archaeology, enabling unprecedented discoveries and detailed analyses. Contrary to traditional radar, LIDAR operates by emitting laser beams at incredibly high frequencies, allowing it to penetrate dense foliage and reveal hidden structures and landscapes.

Advancements in Mapping Hidden Structures

The application of LIDAR in archaeology can be compared to a revolution in the field, with one notable discovery being a small ruin in Yucatán that turned out to be an extensive city. This level of precision and detail would be nearly impossible to achieve without LIDAR. As one archaeologist noted, LIDAR has 'sprinted archaeology ahead by decades'.

Enhanced Mapping and Surveying Techniques

There are several key advantages of using LIDAR in archaeological surveys:

Underwater Surveys: LIDAR can be particularly useful in underwater environments, where it can correct for refraction errors that are challenging for traditional methods. You can explore specific underwater surveys to see how LIDAR is used to create detailed drapes of the seabed. Aerial LiDAR: Discover a range of Hidden Cities that showcase the capabilities of aerial LiDAR. The Naples edition, for instance, concludes with fascinating underwater LiDAR images, highlighting its versatility and power. Non-Invasive Measurement: LIDAR allows for the measurement of topography and other environmental parameters without physical disruption. This means that archaeologists can gather data on previously unobservable features in a non-invasive and efficient manner.

Practical Applications for Site Surveying

The most practical applications of LIDAR in archaeology lie in site surveying and the planning of fieldwork. LIDAR can easily reveal topography hidden under vegetation and dense forest canopies, making it a valuable tool for determining land features and identifying potential sites for further investigation. This method is not only quick but also cost-effective compared to traditional surveying techniques.

3D Scanning: Unlocking New Dimensions in Archaeology

Beyond topography mapping, LIDAR plays a crucial role in 3D object scanning. By creating accurate point clouds, LIDAR enables archaeologists to capture detailed and precise representations of artifacts, buildings, and other significant structures. This capability is invaluable for preservation, restoration, and further study.

Conclusion

LIDAR technology has brought about a paradigm shift in how archaeologists approach the study of historical sites and structures. Its ability to reveal hidden landscapes, measure topography, and scan 3D objects has opened up new frontiers in the field, making it an indispensable tool for modern archaeology.
