Using remote sensing data, including LiDAR (light detection and ranging) and high-resolution satellite imagery, archaeologists are working across scales and mapping sites at levels of detail that once seemed impossible. In parallel, deep learning models are transforming our ability to analyze the resulting large-scale datasets. However, these new developments also present practical and ethical challenges. In this talk, Dr. VanValkenburgh will draw on his own multi-faceted research projects in Peru to discuss how digital approaches are expanding archaeology's reach and scientific impact, while also changing the way that the field works with stakeholders and publics.
