This point shapefile contains imprecise locations of masonry wall remains in Paris based on archaeological references. The points contained in this layer lack the precise information to accurately locate them geographically. These point locations were gathered from archaeological documentation (textual descriptions), or from sources which could no be precisely geolocated. The work of gathering the archaeological information was directed by Etienne Lardkhan. (Univ. Paris-1, ed. D. Aina-Deroin and H. Noizet, 2007-2008). 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. This data is a direct result of the work of the researchers from the ALPAGE consortium who released this data under an Open Data Commons Open Database Licence (ODbL). Therefore, use of this data by others must respect the legal requirements specific to this licence. All freely downloadable data contains the shapefiles, metadata file and licence files describing the users rights and responsibilities. All data produced within the consortium is published in this way with the exception of any ongoing work which is in process of academic evaluation (masters, doctoral thesis, habilitation to supervise research). This layer is presented in the WGS84 coordinate system for web display purposes. Downloadable data are provided in native coordinate system or projection.
