Financing and acknowledgements


The PORTIC (“PORTs & Information and Communication Sciences and Technology.
Querying and visualizing eighteenth-century shipping and trade dynamics in the digital era”) is a program financed by the French National Research Agency within the WP “The digital revolution: relationships to knowledge and to culture” (ANR-18-CE38-0010). Two previous research programs served as an incubator to design PORTIC:

  • The Navi-GO program (2017-2020) funded by the Académie 5 of the UCA-JEDI Future Investments at the University of the Côte d’Azur (funded by the French government, and managed by the National Research Agency,  ANR-15-IDEX-01);
  • DYPOMAR program (Port Dynamics, Urban and Maritime Environments), funded by a CPER / FEDER program of the Nouvelle-Aquitaine region (2014-2020).

PORTIC is also based on two databases produced within the framework of two previous ANR programs:

  • Navigocorpus (ANR-07-CORP-028) coordinated by Silvia Marzagalli;
  • Toflit18 (ANR-13-BSH1-0005) coordinated by Guillaume Daudin and Loïc Charles.
