UML diagram of the data types used in the building base package
and sufficiently: Is the relative height the difference between the topmost point of a
building and the lowest point where the building touches the terrain? Or is it the
difference between the topmost point and the bottom of construction, including
cellars? The INSPIRE building model defines this concept very precisely, by
providing the height reference as well as the low reference the relative height
refers to. The values of both attributes again are defined by the data type Ele-
vationReferenceValue (see Fig.
4
).
The externalReference can be used to obtain further information on the building
from external data stores by storing the id of the building in the data store. This
concept has been borrowed from CityGML.
For representing the name of a building, the complex data type Geographial
Names defined in INSPIRE Annex I (INSPIRE TWG GN
2010
) is used.
If a building is a landmark or is significant from a topographical point of view,
this is denoted by the attribute buildingNature. The usage of the building is rep-
resented by the currentUse attribute. The values are listed in a 'hierarchical code
list' (in such a list, also values on a higher level can be provided):
