The invention relates to a data container (58) for describing room furnishing objects (4, 6, 8) in an interior (2), comprising - an object shape
data vector (68) for describing a shape (72, 74, 76) of a room furnishing object (4, 6, 8) in the interior (2), and - an object transformation
data vector (70) for describing a translation (78), a rotation (80) and a scaling (82) of the room furnishing object (4, 6, 8) within the interior (2), - a wall shape
data vector (68) for describing a shape (72, 74, 76) of a wall (16, 20) delimiting the interior (2), and - a wall transformation data vector (70) for describing the translation (78), a rotation (80) and a scaling (82) of the wall (16, 18) delimiting the interior (2), characterised by - georeferencing data (86) for
labelling a position (88, 90) of the room furnishing object (4, 6, 8) in a
geographic coordinate system.
