The MEDEA-CHART database was created as a tool to assist in the study of medieval and early modern nautical charts. The database also aims to facilitate access to nautical charts for both the scientific community and all members of the public. In short, we collect dispersed information on nautical charts and compile it on a single online platform, available to anyone for free. The development process started about a year and a half ago and is ongoing. MEDEA-CHART project memb
