This polygon shapefile represents the boundaries of three urban areas around Paris, France as they existed during the Middle Ages (ca. 1300). These regions are defined in relation to the Seine River, the right bank (Outre Grand-Point), the City, and the left bank (Outre-Petit-Point).The ALPAGE programme aims to provide collaborative tools for the Humanities and Social Sciences and for Information Communication Technology (ICT) allowing for the development of research about the Parisian urban area. This aim is achieved by means of a GIS that includes cadastral and historical layers.
