Researchers of antiquity around the world share common fundamental problems of fragmentary and patchy information, as well as technical barriers to integrating that information. We are developing two digital humanities tools to alleviate these impediments: 1) LOGAR (Linked Open Gazetteer of the Andean Region), a crowd sourced, edited online gazetteer, and 2) GeoPACHA (Geospatial Platform for Andean Culture, History, and Archaeology), a browser-based geospatial platform for crowdsourcing the locations of colonial towns in Peru. These tools are designed to foster international and interdisciplinary collaborative research on the General Resettlement of Indians in the Viceroyalty of Peru, a forced resettlement program that displaced over a million native Andeans in the late 16th century. Together, LOGAR and GeoPACHA will enable the collective production of the most comprehensive settlement base map of colonial Peru to date, as well as the beginnings of a thematically and analytically deep map of the Viceroyalty of Peru.
