This paper presents an interactive visualization tool tostudy and analyze hyperspectral images (HSI) of historicaldocuments. This work is part of a collaborative effort with theNationaal Archief of the Netherlands (NAN) and Art Innovation, amanufacturer of hyperspectral imaging hardware designed for old andfragile documents. The NAN is actively capturing HSI of historicaldocuments for use in a variety of tasks related to the analysis andmanagement of archival collections, from ink and paper analysis tomonitoring the effects of environmental aging. To assist their work,we have developed a comprehensive visualization tool that offers anassortment of visualization and analysis methods, includinginteractive spectral selection, spectral similarity analysis,time-varying data analysis and visualization, and selective spectralband fusion. This paper describes our visualization software and howit is used to facilitate the tasks needed by our collaborators.Evaluation feedback from our collaborators on how this tool benefitstheir work is included.
