This dataset supports statistical analysis of data collected via the Brittany canals form, which records the passage of boats through locks. It is published as part of the Brittany regional open data portal and provides a basis for monitoring waterway traffic along the region's canal network. The data can be used to study patterns of boat movement and lock usage over time, supporting analysis related to inland waterway navigation in Brittany.Jeu de données permettant l'exploitation statistique des données issues du formulaire canaux de Bretagne permettant de relever le passage des bateaux aux écluses.
