Our analysis focuses mainly on three cadastres of Lausanne (1722, 1831, 1883). The plans are first georeferenced, before being semantically segmented using a neural model, and vectorised. We study the dynamics of persistence using a spatial matching methodology, detecting parcel fusions and divisions through time. We also investigate the social structure of ownership by matching representative owners to their socioprofessional status, based on historical population censuses.encadastral plansvectorisationland ownershipspatial dynamicshistorical social geographytext::conference output::conference proceedings::conference paper
