The team created an ontology to annotate the maps and carried out a workshop which was attended by 27 scholars from UNAM and ENAH, delivering training on Recogito and presenting an introduction to the Spatial Humanities and the use of these technologies. The project coordinators and contributors met online every week to take part in ‘mappathons’ with all our participants, completing the annotation of our full corpus of sixteenth-century maps. This was a collaboration between LLILAS Benson Latin American Studies and Collections at The University of Texas at Austin, the National School of Anthropology and History (ENAH), The National Autonomous University of Mexico (UNAM), the National Institute of Anthropology and History (INAH), and the University of Lisbon.
