The document summarizes the process undertaken by the Royal Tropical Institute to digitize 12,000 of its historical maps. Key aspects of the process included determining copyright and digitization formats, creating transport and progress lists to track digitization, verifying the digital files, georeferencing the maps to allow searching by location, and linking map sheets to index maps for navigation. The goal was to make the collection accessible online while preserving colonial cultural heritage.
