Existing data
• At national level
– Topographical view
– Cadastral view
• At local level
– Lack of overview
– Existence of 3D data
Detailed information available
Lack of exhaustive
information => take care of
feasibility issues during
review and testing

CityGML
• a common model for the representation and the exchange of 3D
city models
– Geometry
– Semantics, relations.
• an international standard from OGC
• a base model with information required by most applications +
possibilities of extensions
• a standard with practical implementations
– Software
– Data
![Page 11: TWG BU Workshop › events › conferences › ... · management Definition of urban areas Urbanism planning and monitoring Pollutions (air, noise, sol) Quality of habitat Sustainable](https://reader033.fdocuments.us/reader033/viewer/2022060412/5f10cf987e708231d44aedcb/html5/thumbnails/11.jpg)
Strong influence of CityGML
• The philosophy of City GML :
– base model (information required by most applications)
– extensions
• CityGML widely used for the modelling of 3D data
– Building model at different levels of detail

Strong influence of CityGML
• Some modelling concepts
– BuildingPart
– ExternalReference : reference to another information system

Methodology
• Identify high level use cases
• Find concrete examples of current use cases
– Survey launched by Joint Research Centre
– TWG BU members proposals
• Collect user requirements (with check-list)
• Analyse user requirements
• Propose application schema for theme Buildings
• Document use cases
– Future use cases
– Using INSPIRE models
![Page 17: TWG BU Workshop › events › conferences › ... · management Definition of urban areas Urbanism planning and monitoring Pollutions (air, noise, sol) Quality of habitat Sustainable](https://reader033.fdocuments.us/reader033/viewer/2022060412/5f10cf987e708231d44aedcb/html5/thumbnails/17.jpg)

Principles
• The profile approach:
– Normative profile: core data
– Illustrative profile: for possible extensions now or in future
• Various user requirements
– Flexible model
• Use of profiles
• Most attributes are voidable
• Most code lists extensible
• Multiple values possible for some attributes
– No recommendation about quality

Main issues
• Is our model feasible?
• Is extension of scope to constructions relevant? Which
benefits? Which costs?
• Should cadastral data (or part of it) be in core profile?
• Should TWG BU propose a more detailed classification
of buildings?
