The Geospatial Platform for Andean Culture, History, and Archaeology (GeoPACHA) is a geospatial platform for systematic archaeological survey over very large areas of Andean South America. Co-Edited by Steven Wernke (Vanderbilt University) and Parker VanValkenburgh (Brown University), GeoPACHA is designed to facilitate the identification of archaeological sites and features through “virtual survey” of satellite and historical aerial imagery and consists of a browser-based interface that enables international teams of trained users to visually scan imagery and record the locations of archaeological sites and features to a central database. GeoPACHA also enables the registry of attribute data (observations on site type, chronology, features present, etc) with identified sites and features via form-based data entry with controlled vocabularies. GeoPACHA is now actively documenting thousands of archaeological sites and features in six survey zones, totaling over 100,000 square kilometers in the central Andes.
GeoPACHA began with the support of a National Endowment for the Humanities Digital Humanities Advancement Grant and a Spatial Archaeometry Collaborations Grant from the Center for Advanced Spatial Technology. A Digital Extension Grant from the American Council of Learned Societies provides current major funding.
