Another talk for readers in Bangkok – this one by Damian Evans on LiDAR in Angkor.
Using Airborne Laser Scanning to Uncover, Map and Analyse Ancient Landscapes in Cambodia & Beyond
A Talk by Dr. Damian Evans
Date: Thursday, 4 February 2016
Time: 7:30 p.m.
Venue: The Siam Society
Traditionally, scholarship on the Angkor period has focussed on three main areas: architecture, inscriptions and art history. In recent years however there has been increasing interest in the human and environmental context of the temples, and archaeologists are beginning to understand much more about the urban and
agricultural networks that stretched between and also far beyond the well-known monuments of places like Angkor. Even though the cities that surrounded the temples were made of wood, and the water management systems were mostly made of earth, we can still very clearly see and map the traces that remain on the surface of the landscape using remote sensing techniques such as aerial photos and satellite imagery. Until recently, however, archaeologists who focussed on the mapping methods faced one very serious limitation: the fact that vegetation covers much of the areas of interest, and limits our ability to see and map these ancient features. Since 2012 however archaeologists in Cambodia have been using the technique of airborne laser scanning or “lidar”, which has the unique ability to “see through” vegetation and map archaeological remains, even underneath thick forest or jungle. This presentation will outline past, present and future projects involving lidar, including presenting some preliminary results from the latest lidar campaign in 2015, which increased coverage from Angkor to include a wide array of sites across Cambodia, and discuss potential applications in other countries in Southeast Asia including Thailand.
