  6. General methodology

  7. General process Constraint Existing data Drivers Use cases User requirements Data specification INSPIRE TWG Support Standards Best practices

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

  9. Existing standards

  10. 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

  11. 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

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

  13. LADM (Land Administration Domain Model) Ex: a flat in a block of flats (in case of co-ownership) Legal/cadastral point of view on buildings

  14. Eurostat classification Eurostat classification partly adopted (for residential use)

  15. Use cases

  16. 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

  17. High level use cases Census - Statistics Safety – risk management Urban expansion Utility and Governmental services Environment Communication – Public awareness

  18. Concrete use cases Census - Statistics Census Urban units Environmental statistics / Reporting Urban expansion Infrastructures Environment Safety Natural risks (flood, fire, earthquake, landslide) Human risks (transport) Prevention / rescue management Pollutions (air, noise, sol) Quality of habitat Sustainable buildings (energy, …) Historical interest Definition of urban areas Urbanism planning and monitoring Location for new infrastructure Infrastructure management Public patrimony management and valorisation City maps Thematic / tourism maps Risk / travel maps 3D models Communication – Public awareness

  19. Check-list User requirements collected with check-list Around 80 check-lists collected (mainly by interviews of users)

  20. Analysis of user requirements Topographic data (including Buildings) Extent of physical phenomenon Propagationmodel Physical phenomenon data • Building influence on physical phenomena Examples: flood, noise, air pollution, light

  21. Building influence on physical phenomena Analysis of user requirements Influence of buildings on air pollution propagation

  22. Influence of physical phenomena on buildings Analysis of user requirements Building data Building vulnerability or ability Analysis Physical phenomenon data • Examples: • flood, fire, earthquake, noise, … : vulnerability to risk or pollution • sun exposure: ability to receive solar panels

  23. Analysis of user requirements • Physical phenomena modelling: • different models more or less detailed Simple data: cheaper (widely available data) but only rough results Detailed data : good results but costly(rarely available data) 3D geometry Material of roof Material of walls Material of structure … 2D geometry Height Date of construction Date of renovation OR

  24. Area of interest Buildings Analysis of user requirements • Computation of population SU SU Statistical data on statistical units Examples: flood, noise, air pollution, light, transport

  25. Analysis of user requirements • Computation of population Population at night Population at day • 2D geometry • Localisation • area • Number of floors • Use • Residential • Industrial • Office • Retail • Public services • -2D geometry • Localisation • area • Number of floors • Use (residential)

  26. Mapping Analysis of user requirements Flooded areas map Noise map around airport Symbols for Electronical Navigation Charts Roof thermography (lost of heat)

  27. Analysis of user requirements • Mapping (e.g. air traffic or marine navigation) Buildings and constructions 2D geometry Height Elevation Classification according to physical aspect Specific buildings and constructions may be landmarks (or obstacles)

  28. Specific buildings and constructions (examples)

  29. Analysis of user requirementsDefinition of urban / artificial areas Urban atlas (GMES) Current land use map Cartographic generalisation 2D geometry – use – number of floors – condition (functional, in project, ruin,…)

  30. Analysis of user requirements3D models Demolition or construction project Communicationabout risk Valorisation of territory

  31. Analysis of user requirements3D models 3D geometry Texture Textures from libraries or from real-world images

  32. Analysis of user requirementsUrbanism planning- Urban monitoring Temporal studies: evolution of city

  33. Analysis of user requirementsUrbanism planning- Urban monitoring Detailed cadastral data for urbanism management

  34. Analysis of user requirements 2D geometry Date of construction Date of demolition Condition (functional, in project, ruin,…) Official area Link to building permit (document, external reference) Access to owner External Reference on Building Association to Cadastral Parcel External Reference on Building Unit Building geometry Spatial overlay with Cadastral Parcel

  35. Analysis of user requirements • Census of population and dwellings: 2D geometry Residential buildings questionnaire reference data Period of construction State of repair Number of floors Use of building Material Number of dwellings Heating / toilet / water Period of construction State of repair Number of floors Use of building Material Number of dwellings Heating / toilet / water

  36. Harmonisation of interest for European user(s) Harmonisation of interest for national/local user(s) European Directives/initiatives INSPIRE Directive/GCM European Directives/initiatives International use cases Localuse cases Building/BuildingPart OtherConstruction inspireId heightAboveGround BuildingUnit Association to AD numberOfFloors Widely available currentUse elevation beginLifespanVersion Association to CP dateOfConstruction endLifespanVersion dateOfRenovation officialArea conditionOfConstruction externalReference dateOfDemolition officialValue numberOfDwellings specificInterest name constructionNature numberOfBuildingUnits heightBelowGround numberOfFloorsBelowGround materialOfStructure document Rarely available materialOfRoof materialOfFacade roofType openGroundFloor energyPerformance

  37. Profile approach

  38. Harmonisation at European level Harmonisation at national/local level Out of INSPIRE theme BU Owner/tenant Basic cadastral data Basic topographic data Widely available Detailed activity Interior of building Detailed topographic data Rarely available Core profile Extended profile

  39. Documentation of use cases – (annex B)

  40. Modelling approach

  41. 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

  42. Core 2D profile Scope of theme Building has been enlarged to include feature type OtherConstruction (e.g. bridges, environmental barriers, elevated constructions)

  43. Extension of scope • Feature type : OtherConstruction

  44. Core 2D profile Common attributes of OtherConstruction and AbstractBuilding are grouped under feature type AbstractConstruction Common attributes to feature types Building and BuildingPart • Only 3 instanciable feature types: • Building • BuildingPart • OtherConstruction

  45. Geometry Multiple geometry allowed Reference geometry to be used for queries and portrayal • Example of geometry

  46. Elevation ElevationCRSReference Multiple values of elevation allowed • Example of elevation

  47. Classification of buildings Based on Eurostat classification Mainly based on international use cases (air traffic, marine navigation) More information to be found in themes AF, PF and US • Current status classification according to: • the activity hosted by the building (for management use cases) • the physical aspect (for mapping purposes) Both code lists are extensible by MS

  48. Extended 2D profile Association to AD Association to CP New feature type BuildingUnit: subdivision of Building that is homogeneous related to management aspects.

  49. Extended 2D profile Attributes related to the architecture of buildings Attributes related to management of buildings (cadastral data)

  50. Core 3D profile Based on LoD 1 of CityGML (the simplest one)
