The authors are developing a lidar-based computer model that uses convolutional neural networks to identify ancient Maya landscape features under dense Central American forest canopy. Thus far, we have completed and ground-verified a model that uses a random forest classifier to identify cave entrances at a 260-km2 Maya site in Belize. We are now expanding this work to generate a predictive model for identification of undiscovered, overgrown ancient Maya architecture in Guatemala and Mexico. Recent applications of sub-meter resolution lidar imagery to such sites has revealed huge areas of previously unknown architecture. However, it has all been identified by slow, hit-or-miss visual inspection. We are automating this process by generating a machine-learning model based on a large training dataset, drawing from the fields of computer vision and machine-learning. This work will help archaeologists and cave scientists to quickly identify study areas and produce accurate maps for efficient management of resources. Additionally, models that can automatically identify features of interest using aerial imagery are highly relevant across a broad range of fields both inside and outside academia, including natural hazard prediction and urban planning.
