Summary

Sponsored by the Pennsylvania Department of Transportation (PennDOT), this project endeavored to create a statewide Archaeological Predictive Model (APM) based on the known locations of over 18,000 recorded pre-contact archaeological sites within the Commonwealth. The purpose of this project was to create a set of sensitivity maps to aide in transportation planning and assist in the cultural resources management process. The creation of an APM covering 46,000 square miles required the development of a new set of computational and statistical tools for the storage and management of massive datasets, the use of parallel and "cloud" computing to apply modern statistical methods, and the adaptation of data science techniques developed in fields such as biology, ecology, and medicine. While the resultant approach was grounded in the lessons of nearly 40 years of APM study, the project demanded a fundamental rethinking of our field’s approaches and expectations. This presentation will explore the project’s mission, outline the computational framework and statistical methods used, evaluate the findings, and discuss the benefits and challenges of such an approach.
