6 General methodology

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

8 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

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 Some modelling concepts BuildingPart BuildingPart ExternalReference : reference to another information system

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

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

15 Use cases

16 Identify high level use cases Methodology 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 Environment Utility and Governmental services Communication Public awareness

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

19 Check-list User requirements collected with check-list Use cases category Safety Urban expansion Environment Around 80 check-lists collected (mainly by interviews of users) Utilities and Governmental Services Statistics Public awareness

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

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

22 Analysis of user requirements Influence of physical phenomena on buildings Building data Physical phenomenon data Analysis Building vulnerability or ability 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 3D geometry Material of roof Material of walls Material of structure OR 2D geometry Height Date of construction Date of renovation Simple data: cheaper (widely available data) but only rough results Detailed data : good results but costly (rarely available data)

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

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

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

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 requirements Definition 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 requirements 3D models Demolition or construction project Communication about risk Valorisation of territory

31 Analysis of user requirements 3D models 3D geometry Texture Textures from libraries or from realworld images

32 Analysis of user requirements Urbanism planning- Urban monitoring Temporal studies: evolution of city

33 Analysis of user requirements Urbanism 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 External Reference on Building Unit Building geometry Spatial overlay with Cadastral Parcel Association to Cadastral Parcel

35 Analysis of user requirements Census of population and dwellings: 2D geometry Residential buildings reference data questionnaire 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) INSPIRE Directive/GCM International use cases European Directives/initiatives European Directives/initiatives Local use cases Building/BuildingPart OtherConstruction Widely available inspireid beginlifespanversion endlifespanversion externalreference elevation heightaboveground numberoffloors currentuse dateofconstruction dateofrenovation conditionofconstruction dateofdemolition BuildingUnit Association to CP Association to AD officialarea officialvalue name specificinterest constructionnature numberofdwellings numberofbuildingunits heightbelowground Rarely available numberoffloorsbelowground materialofstructure materialofroof materialoffacade rooftype opengroundfloor document energyperformance

37 Profile approach Basic semantic Rich semantic 2D geometry 3D geometry Core 2D profile (normative) Core 3D profile (normative) Extended 2D profile (illustrative) Extended 3D profile (illustrative)

38 Harmonisation at European level Harmonisation at national/local level Out of INSPIRE theme BU Widely available Basic topographic data Basic cadastral data Owner/tenant Detailed activity Interior of building Rarely available Detailed topographic data 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 to feature types Building and BuildingPart Common attributes of OtherConstruction and AbstractBuilding are grouped under feature type AbstractConstruction Only 3 instanciable feature types: -Building -BuildingPart -OtherConstruction

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

46 Elevation Example of elevation ElevationCRSReference Multiple values of elevation allowed

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

48 Association to CP Association to AD Extended 2D profile 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)

52 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?
