With support from the Getty Foundation, the Humanities Research Center (HRC) at Rice University will collaborate with the Instituto Moreira Salles (IMS) in Rio de Janeiro on a two-year project to digitally integrate historical photography and cartography into imagineRio, a platform that charts changes in the city's landscape and topography over time. The project will digitize 4,000 photographic views of Rio de Janeiro from the 19th and 20th centuries in the IMS collection and incorporate them into the existing model, greatly expanding the number and variety of geo-located visual representations of Rio accessible to researchers. The project contributes to the understanding of the evolution of Rio de Janeiro and its built environment, and by extension other cities, through the integration of its photographic and cartographic heritage. Using innovative technologies such as monoplotting, photographs can be geo-referenced down to the level of individual pixels. The project will also develop new models to generate a 3D version of imagineRio from archival data and digitized historical photographs.
