NOTE: This is very experimental, and far from finished!
      To generate the source data: BD-L-TC and PCN/Batiments.shp are merged in QGIS
	  	Vector -> Data Management Tools -> Join Attributes by Location
		  Input Layer: PCN
		  Join Layer: BD-L-TC
		  Geometric predicate: intersects, contains, equals, overlaps, within
		  Join Type: "Create separate feature for each located feature (one-to-many)"
