Alpage
AnaLyse diachronique de l'espace urbain PArisien : approche GEomatique ALPAGE is a geohistorical information platform for Paris. It is based on a work dynamic initiated in 2006, thanks to support from the Agence Nationale de la Recherche (French National Research Agency), and which has continued beyond the funded phase (2006-2010). The initial project brought together some twenty researchers coordinated by LAMOP member Hélène Noizet. These historians, geomaticians and computer scientists laid the foundations for a geographic information system (GIS) on pre-industrial Paris. Spatial reference data for the early 19th century and the medieval period have been put online in a cartographic platform accessible to all, and most of them are freely downloadable. The associated metadata identify the sources and authors of each piece of data. The initial group, founded on the association of 4 laboratories, and the collaboration of numerous other partners, has evolved into a network of researchers and students working on the history of Paris, without dedicated funding. It is regularly enriched by contributions from researchers of different backgrounds, enabling us to broaden the range of themes and periods covered. Each researcher, according to his or her own interests, creates new geohistorical data on Paris. The cartographic platform, hosted by TGIR Humanum, is updated once or twice a year to incorporate new data, validated by the administrators (Hélène Noizet, Laurent Costa, Eric Grosso) and/or the group's referents (Boris Bove, Sandrine Robert). At the same time, this website, which offers data for download, is updated by the webmaster (Davide Gherdevich). The group is open to anyone interested in spatial history in Paris. A wealth of data has been compiled, not only for the medieval period, but also for the modern period and the 19th century. With regard to the geographical scale, which is still limited to Paris, a partnership with the Archéologies du Bassin Parisien program of UMR 7041 ArScAn provides access to geohistorical repositories on the scale of the Paris basin. Finally, in addition to the webmapping platform, the ALPAGE group has published a book (Paris de parcelles en pixels), and a plan of Paris at the beginning of the 19th century in A1 and A2 format (ALPAGE-Vasserot plan).
