comment: Type for addresses. It references the xAL address standard issued by the OASIS consortium. Please note, that addresses are modelled as GML features. Every address can be assigned zero or more 2D or 3D point geometries (one gml:MultiPoint geometry) locating the entrance(s).

CityModel

subclass of: FeatureCollection
comment: Type describing the "root" element of any city model file. It is a collection whose members are restricted to be features of a city model. All features are included as cityObjectMember.

ExternalReferenceType
type: Class
comment: Type describing the reference to an corresponding object in an other information system, for example in the german cadastre ALKIS, the german topographic information system or ATKIS, or the OS MasterMap. The reference consists of the name of the external information system, represented by an URI, and the reference of the external object, given either by a string or by an URI. If the informationSystem element is missing in the ExternalReference, the ExternalObjectReference must be an URI, which contains an indication of the informationSystem.

GeneralizationRelationType

comment: Type for the implicit representation of a geometry. An implicit geometry is a geometric object, where the shape is stored only once as a prototypical geometry, e.g. a tree or other vegetation object, a traffic light or a traffic sign. This prototypic geometry object is re-used or referenced many times, wherever the corresponding feature occurs in the 3D city model. Each occurrence is represented by a link to the prototypic shape geometry (in a local cartesian coordinate system), by a transforma-tion matrix that is multiplied with each 3D coordinate tuple of the prototype, and by an anchor point denoting the base point of the object in the world coordinate reference system. In order to determine the absolute coordinates of an implicit geometry, the anchor point coordinates have to be added to the matrix multiplication results. The transformation matrix accounts for the intended rotation, scaling, and local translation of the prototype. It is a 4x4 matrix that is multiplied with the prototype coordinates using homogeneous coordinates, i.e. (x,y,z,1). This way even a projection might be modelled by the transformation matrix. The concept of implicit geometries is an enhancement of the geometry model of GML3.
comment: Denotes the relation of a _CityObject to its implicit geometry representation, which is a representation of a geometry by referencing a prototype and transforming it to its real position in space. The ImplicitGeometry element must either carry a reference to a ImplicitGeometry object or contain a ImplicitGeometry object inline, but neither both nor none.

comment: Type describing the abstract superclass of most CityGML features. Its purpose is to provide a creation and a termination date as well as a reference to corresponding objects in other information systems. A generalization relation may be used to relate features, which represent the same real-world object in different Levels-of-Detail, i.e. a feature and its generalized counterpart(s). The direction of this relation is from the feature to the corresponding generalized feature.

comment: Specialization for georeferenced textures, i.e. textures using a planimetric projection. Such textures contain an implicit parameterization (either stored within the image file, in an acompanying world file, or using the "referencePoint" and "orientation"-elements). A georeference provided by "referencePoint" and "orientation" always takes precedence. The search order for an external georeference is determined by the boolean flag preferWorldFile. If this flag is set to true (its default value), a world file is looked for first and only if it is not found the georeference from the image data is used. If preferWorldFile is false, the world file is used only if no georeference from the image data is available. The "boundedBy"-property should contain the bounding box of the projected image data. Since a georeferenced texture has a unique parameterization, "target" only provides links to surface geometry without any additional texture parameterization. Only gml:MultiSurface or decendants of gml:AbstractSurfaceType are valid targets.

comment: Texture parameterization using a transformation matrix. The transformation matrix "worldToTexture" can be used to derive texture coordinates from an object's location. This 3x4 matrix T computes the coordinates (s,t) from a homogeneous world position p as (s,t) = (s'/q', t'/q') with (s', t', q') = T*p. Thus, perspective projections can be specified. The SRS can be specified using standard attributes. If an object is given in a different reference system, it is transformed to the SRS before applying the transformation. A transformation matrix can be used for whole surfaces. It is not required to specify it per LinearRing.

comment: Texture parameterization using texture coordinates: Each gml:LinearRing that is part of the surface requires a separate "textureCoordinates"-entry with 2 doubles per ring vertex. The "ring"- attribute provides the gml:id of the target LinearRing. It is prohibited to link texture coordinates to any other object type than LinearRing. Thus, surfaces not consisting of LinearRings cannot be textured this way. Use transformation matrices (see below) or georeferenced textures instead.

comment: Type describing the thematic and geometric attributes and the associations of bridges. It is an abstract type, only its subclasses Bridge and BridgePart can be instantiated. An _AbstractBridge may consist of BridgeParts, which are again _AbstractBridges by inheritance. Thus an aggregation hierarchy between _AbstractBridges of arbitrary depth may be specified. In such an hierarchy, top elements are Bridges, while all other elements are BridgeParts. Each element of such a hierarchy may have all attributes and geometries of _AbstractBridges. It must, however, be assured that no inconsistencies occur.

comment: Denotes the relation of an _AbstractBridge to its bounding thematic surfaces (walls, roofs, ..). The _BoundarySurface element must either carry a reference to a _BoundarySurface object or contain a _BoundarySurface object inline, but neither both nor none. There is no differentiation between interior surfaces bounding rooms and outer ones bounding bridges (one reason is, that ClosureSurface belongs to both types). It has to be made sure by additional integrity constraints that, e.g. an _AbstractBridge is not related to CeilingSurfaces or a room not to RoofSurfaces.

comment: Type describing the thematic and geometric attributes and the associations of buildings. It is an abstract type, only its subclasses Building and BuildingPart can be instantiated. An _AbstractBuilding may consist of BuildingParts, which are again _AbstractBuildings by inheritance. Thus an aggregation hierarchy between _AbstractBuildings of arbitrary depth may be specified. In such an hierarchy, top elements are Buildings, while all other elements are BuildingParts. Each element of such a hierarchy may have all attributes and geometries of _AbstractBuildings. It must, however, be assured than no inconsistencies occur (for example, if the geometry of a Building does not correspond to the geometries of its parts, or if the roof type of a Building is saddle roof, while its parts have an hip roof). As subclass of _CityObject, an _AbstractBuilding inherits all attributes and relations, in particular an id, names, external references, and generalization relations.

comment: A BoundarySurface is a thematic object which classifies surfaces bounding an _AbstractBuilding, Room, BuildingInstallation, and IntBuildingInstallation. The geometry of a BoundarySurface is given by MultiSurfaces. As it is a subclass of _CityObject, it inherits all atributes and relations, in particular the external references, and the generalization relations.
comment: Denotes the relation of an _AbstractBuilding to its bounding thematic surfaces (walls, roofs, ..). The _BoundarySurface element must either carry a reference to a _BoundarySurface object or contain a _BoundarySurface object inline, but neither both nor none. There is no differentiation between interior surfaces bounding rooms and outer ones bounding buildings (one reason is, that ClosureSurface belongs to both types). It has to be made sure by additional integrity constraints that, e.g. an _AbstractBuilding is not related to CeilingSurfaces or a room not to RoofSurfaces.

comment: A group may be used to aggregate arbitrary CityObjects according to some user-defined criteria. Examples for groups are the buildings in a specific region, the result of a query, or objects put together for visualization purposes. Each group has a name (inherited from AbstractGMLType), functions (e.g., building group), a class and zero or more usages. A geometry may optionally be attached to a group, if the geometry of the whole group differs from the geometry of the parts. Each member of a group may be qualified by a role name, reflecting the role each CityObject plays in the context of the group. As subclass of _CityObject, a CityObjectGroup inherits all attributes and relations, in particular an id, names, external references, and generalization relations. As CityObjectGroup itself is a CityObject, it may also be contained by another group.

CityObjectGroupMemberType

comment: Denotes the relation of a CityObjectGroup to its parent, which is a CityObject. The CityObjectGroupParentType element must either carry a reference to a _CityObject object or contain a _CityObject object inline, but neither both nor none. The parent association allows for modelling of a generic hierarchical grouping concept. Named aggregations of components (CityObjects) can be added to specific CityObjects considered as the parent object. The parent association links to the aggregate, while the parts are given by the group members.

comment: Generic (user defined) city objects may be used to model features which are not covered explicitly by the CityGML schema.

AbstractAppearance
type: Class
subclass of: AbstractGMLType
comment: Deprecated since CityGML version 0.4.0. Use the concepts of the CityGML Appearance module instead. This abstract type is the parent type of Material and SimpleTexture. It is derived from gml:AbstractGMLType, thus it inherits the attribute gml:id and may be referenced by an appearanceProperty, although it is defined elsewhere in another appearanceProperty.

Appearance
type: Class
comment: Deprecated since CityGML version 0.4.0. Use the concepts of the CityGML Appearance module instead. A property that has an _Appearance as its value domain, which can either be a Material (Color,...) or a Texture. The _Appearance Element can either be encapsulated in an element of this type or an XLink reference to a remote _Appearance element (where remote geometry elements are located in another document or elsewhere in the same document). Either the reference or the contained element must be given, but neither both nor none. The side of the surface the _Appearance refers to is given by the orientation attribute, which refers to the corresponding sign attribute of the orientable surface: + means the side with positive orientation, and - the side with negative orientation.

TexturedSurface
type: Class
subclass of: OrientableSurface
comment: Deprecated since CityGML version 0.4.0. Use the concepts of the CityGML Appearance module instead. The concept of positioning textures on surfaces complies with the standard X3D. Because there has been no appropriate texturing concept in GML3, CityGML adds the class TexturedSurface to the geometry model of GML 3. A texture is specified as a raster image referenced by an URI, and can be an arbitrary resource, even in the internet. Textures are positioned by employing the concept of texture coordinates, i.e. each texture coordinate matches with exactly one 3D coordinate of the TexturedSurface. The use of texture coordinates allows an exact positioning and trimming of the texture on the surface geometry. Each surface may be assigned one or more appearances, each refering to one side of the surface.

comment: Abstract super class of the features RoofSurface, WallSurface, GroundSurface, ClosureSurface, FloorSurface, OuterFloorSurface, CeilingSurface and OuterCeilingSurface
comment: Denotes the relation of an tunnel or hollow space to its bounding thematic surfaces (walls, roofs, ..). There is no differentiation between interior surfaces bounding hollow spaces and outer ones bounding tunnels (one reason is, that ClosureSurface belongs to both types). It has to be made sure by additional integrity constraints that, e.g. a tunnel is not related to CeilingSurfaces or a room not to RoofSurfaces.

comment: Type describing solitary vegetation objects, e.g., trees. Its geometry is either defined explicitly by a GML 3 geometry with absolute coordinates, or in the case of multiple occurences of the same vegetation object, implicitly by a reference to a shape definition and a transformation. The shape definition may be given in an external file. As subclass of _CityObject, a SolitaryVegetationObject inherits all attributes and relations, in particular an id, names, external references, and generalization relations.
