Identification on the regional territory of all built elements prior to the mid-20th century (designation, location, dating, health status).
__Origin__
The geographical position of the inventoried elements is treated in the form of a point from funds such as the Ortho BD (corrected ortho aerial photography), as well as the layers of the modern cadastre (parcellar and built). The seized polygons were transformed into a point by taking the centroid from it.
