In France, the existing road network geohistorical data is limited to the digitization of the Cassini maps (18th century)1 and to the current work of ANR COMMUNES research team on the French military maps (19th century)2. That is why, COVADEO project aims to complete those works by conceiving a crowdsourced solution to collect geometries of ancient road networks.
To do so, the project proposes the development of a web platform, applied to the Burgundy-Franche-Comté region (BFC). Firstly, 440 historical maps were collected, allowing the reading of road networks from the 17th century to the 20th all over the region BFC. Secondly, a well-conceived database model was designed to store those maps and their important metadata as well as the ancient road network geometries. Finally, the web platform was conceived as a serious game, giving users the opportunity to input ancient geometries from the ones of the current network. A test version of this platform3 has been launched online in order to understand the stakes of such a mode of data production. It allowed us to enhance the game mechanisms to involve a large community in collaborative data production.
This innovative methodology of data collection will allow us to analyze in-depth historical evolution of road networks.
