This paper presents part of a research carried out as a graduation project which investigated new approaches for viewing the digital collection of graduation projects of the School of Architecture and Urbanism at the Federal University of Rio de Janeiro - the “Portal Midiateca”. In addition to visualization, the objective is also to survey open source tools and document the process, enabling other researchers to have access to instruments for analysis and visualization of cultural collections. The visualizations and analysis used as data the images (hue, saturation, brightness, similarity) and metadata (themes and year of publication) of the graduation projects sent by the students. They were made using VIKUS Viewer to examine the collection in a dynamic website with timeline and similarity visualization tools; and ivpy in a notebook environment to produce static mosaics from different groups of images according to their color measurements.
