This dataset provides the digitised road network of the Grange area in the Canton of Geneva, covering the period 1896-1911. It was produced by the Geneva territorial information system (Système d'information du territoire genevois). The network was derived in two stages: first by subtracting the DPS_GRANGE_PARC layer from a polygon representing the town boundary, producing a polygon that is the negation of the parcel layer, and then processing this result to obtain the road network itself. The dataset is of local geographic scope, limited to the Grange sector.La digitisation du réseau viaire de Grange a été réalisée en deux temps. Dans un premier temps, le réseau viaire a été obtenu par la soustraction de la couche DPS _GRANGE _PARC à un polygone représentant le contour de la ville. Il en a résulté un polygone, qui constitue donc la "négation" de la cou…
