PCRS of the Metropolis of Lyon - Facade

Class of objects FacadePCRS describing all building facades whether public or private and represented by a polyline. The façade is raised to the level of the ‘nude’ of the main wall at the height of the basement or sidewalk. In accordance with what is stipulated in the standard, this class of objects does not include the fore-body (forward volumes) or the rear-body (backward volumes) giving the facade relief from the ‘nude’ of the main wall. Hard buildings and light buildings must be lifted. Finally, it is important to add that when there is a threshold, the polyline of the facade is interrupted at the dive point of the threshold. A new polyline is then represented from the other threshold.
