A large area overgrown with vegetation will soon be undergoing development. You have been given a large budget to urgently identify and map stone walling using remote sensing so that developers can avoid disturbing archaeological sites. Which of the follo

Given the urgency of the task and the need to accurately identify and map stone walling while minimizing disturbance to archaeological sites, the best approach among the options provided is: **2. Carry out an airborne LiDAR survey of the study area.** Airborne LiDAR (Light Detection and Ranging) is a highly effective remote sensing technique that can penetrate vegetation canopies and produce detailed topographic maps, revealing features such as stone walls that may be obscured by dense foliage. This method is non-invasive and provides high-resolution data, making it a suitable choice for quickly identifying archaeological features in an overgrown area. The other options, such as waiting for the dry season or using satellite images, may not provide the same level of detail or immediacy as airborne LiDAR, and burning vegetation is not an acceptable or ethical approach.
