Balcony

ISO 6707-1(2004): Upper accessible platform within a storey, not fully enclosed by wall(s).

An external balcony is an accessible platform that projects from the external face of a building.

An internal balcony or recessed balcony (US) is an accessible platform recessed from the external face of a building.

Ceiling

Wikipedia: A ceiling is an overhead interior surface that covers the upper limit of a room. It is not generally considered a structural element, but a finished surface concealing the underside of the floor or roof structure above.

Compound Coordinate Referencesystem (CCRS)

ISO 19111: Coordinate reference system using two other independent coordinate reference systems to describe a position.

The horizontal and vertical components of a description of position in three dimensions may sometimes come from different coordinate reference systems rather than through a single three-dimensional coordinate reference system. This is always the case for positions where vertical coordinates are related to mean sea level. This shall be handled through a compound coordinate reference system which identifies the two coordinate reference system utilized.

Notification by using a "*" combining the two coordinate reference systems, e.g. DE_DHDN_3GK2_RDN*DE_DHHN92_NH

Door

Wikipedia: A door is an opening or closing structure used to block off an entrance, typically consisting of an interior side that faces the inside of a space and an exterior side that faces the outside of that space. While in some cases the interior side of a door may match its exterior side, in other cases there are sharp contrasts between the two sides, such as in the case of the vehicle door. In addition, doors typically consist of a panel that swings on hinges or that slides or spins inside of a space.

ISO 6707-1(2004): Construction for closing an opening intended primarily for access or egress or both.

F

Floor

Wikipedia: A floor is the walking surface of a room or vehicle. Floors vary from simple dirt in a cave to many-layered surfaces using modern technology. Floors may be stone, wood, bamboo, metal, or any other material that can hold a person's weight.

The levels of a building are often referred to as floors although a more proper term is storey.

O

Opening

CityGML: Abstract class for door and window

R

Roof

Wikipedia: A roof is the covering on the uppermost part of a building. A roof protects the building and its contents from the effects of weather and the invasion of animals. Structures that require roofs range from a letter box to a cathedral or stadium, dwellings being the most numerous.

ISO 6707-1(2004): Construction that encloses a building from above. ISO 6707-1(2004) classifies the following roof types:

flat roof is a roof either horizontal or with a slope of 10° or less.

pitched roof is a roof, the slope of which is greater than 10° (approximately 15 %)

shed roof or monopitch roof is a pitched roof that has only a single plane

lean-to roof is a monopitch roof that has its upper edge attached to, and supported by, a wall that extends above the level of the roof, or is supported by structural member(s) next to or attached to a wall

shell roof or domed roof is a roof formed of a thin curved structural slab

mansard roof is a pitched roof with two inclined planes on each side of the ridge, the steeper of the two starting at the eaves

gable roof is a pitched roof that terminates at one or both ends as a gable

hipped roof or hip roof is a pitched roof with hip end or ends

sawtooth roof is a series of pitched roofs, each with one inclined plane steeper than the other and fully or partially glazed

S

Storey

ISO 6707-1(2004): Space between two consecutive floors or between a floor and a roof.

W

Wall

Wikipedia: A wall is a vertical structure, usually solid, that defines and sometimes protects an area. Most commonly, a wall delineates a building and supports its superstructure, separates space in buildings into sections, or protects or delineates a space in the open air. There are three principal types of structural walls: building walls, exterior boundary walls, and retaining walls.

ISO 6707-1(2004) Vertical construction that bounds or subdivides a space and usually fulfils a loadbearing or retaining function.

Window

Wikipedia: A window is a transparent or translucent opening in a wall, door or vehicle that allows the passage of light and, if not closed or sealed, air and sound. Windows are usually glazed or covered in some other transparent or translucent material. Windows are held in place by frames. Many glazed windows may be opened, to allow ventilation, or closed, to exclude inclement weather.

ISO 6707-1(2004) Construction for closing a vertical or near-vertical opening in a wall or pitched roof, which will admit light and may provide ventilation.
