Archaeological Prospection by Lidar Beyond Simple Hillshading
For more than a decade, Lidar data has been used to detect and delimit archaeological sites by highlighting subtle altitude differences generated by the remains of these sites. Simple hillshading Web Map Services with a resolution of 1 m are provided by some Ordnance Survey Institutions in Europe:
The above image shows a four-sided most probably Roman structure including some interior features and many later sites such as a bundle of paths in a forested area in Germany.
New interpolation of the ground points resulting in a higher resolution image and alternative visualisation methods often provide images that show the archaeological features more clearly:
If you want to know more about such methods, you are most welcome to attend the Lidar session at the CHNT conference.
If you can do better than that, for instance
- if the Lidar data acquired by your own devices outperforms Ordnance Survey data or
- if you successfully recorded Lidar data in regions without low-cost or free-of-charge availability of Lidar data,
- if you use improved methods for identifying ground points in densely vegetated areas,
- if you apply pattern recognition and machine learning approaches for the (semi-)automatic detection of archaeological sites in Lidar data,
- or if you combine Lidar data with other archaeological data in new ways
you are cordially invited to contribute by submitting an abstract for the Lidar session at the CHNT conference.
