Abstract
The relatively recent availability of terrestrial lidar for mapping archaeological subjects has allowed for great advances in representation and reconstruction but the analytic potential of this technology remains under-developed in archaeology. This paper provides an overview of the analytical directions we are taking with point cloud data generated through ground-based laser scanning at the imperial Inca site of Caranqui in northern Ecuador. Our approach to data analysis employs insights and ideas from the domains of GIScience, remote sensing, cartography, computer vision and hydrology. While creating a comprehensive visual record of the site was an important project goal, we also sought to develop improved methods of feature extraction and surface calibration to better understand water manipulation and flows at the site. Here we highlight some of the preliminary results of our analyses as well as the challenges and benefits of employing terrestrial lidar to investigate a mid-sized archaeological site.
