The document discusses lidar and its applications in landscape archaeology. It begins with an overview of how lidar works and its technical capabilities. It then explores various visualization techniques used to analyze lidar data, including digital elevation models, hillshades, and models of slope and solar radiation. Applications of lidar in archaeology are also examined, such as mapping sites, erosion, and buried environments. The document concludes by noting the large volumes of data collected from lidar pose challenges for effective analysis and interpretation.
