During the FOSSGIS Conference in Münster Stefan Fuest and Maximilian Herbers presented various methods for visualising ship routes with uncertain data, using the open-source geographic information system software QGIS and the JavaScript library MapLibre GL JS for creating interactive maps. The cartographic representation is based on an AI-supported extraction of imprecise location and time references from sources, such as logbooks and journals from the 18th and 19th century, which are then modelled in a PostgreSQL database - an exciting project with Andreas Gollenstede, Rieke Marie Kaiser & Jennifer Tadge!
