The MEDEA-CHART Database is an online free-of-charge information system dedicated to old nautical charts, created under the European Research Council project MEDEA-CHART. The system holds digital images and information about medieval and early modern nautical charts and atlases from circa 1250 onwards. Content is managed by project members.
Database entries created with the help of ‘Census of Portolan Charts and Atlases’, Richard Pflederer; originally published in 2009 as a hard bound book with frequent digital updates since then.
