House rings are georeferenced circumferential polygons of building floor plans derived from the Official Property Register Information System (ALKIS). They thus form the graphical/geometric addition to the house coordinates. Property attributes such as municipality, street, house number or postal information are not included in the house circles (determine, if necessary, by intersection, e.g. with house coordinates). The database includes main buildings and outbuildings.
