1 Data Specification Buildings KEN INSPIRE Workshop INSPIRE Theme Buildings Status after consultation and testing

2 Plan of presentation General methodology, existing data and standards Use cases user requirements Modelling approach Open issues Consultation and testing

3 General methodology

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

5 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

6 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

7 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

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

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

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

11 Use cases

12 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

13 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

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

15 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

16 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),quicker to process but only rough results Detailed data : good results but costly (rarely available) and longer to process

17 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

18 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

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

20 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)

21 Specific buildings and constructions (examples)

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

23 Analysis of user requirements Urbanism planning- Urban monitoring Detailed cadastral data for urbanism management

24 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

25 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 heightaboveground numberoffloors elevation 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

26 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)

27 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

28 Modelling approach

29 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

38 Main issues

39 Extension of scope Feature type : OtherConstruction Open issue : is this extension relevant? (useful? difficult?)

40 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 heightaboveground numberoffloors elevation currentuse dateofconstruction dateofrenovation conditionofconstruction dateofdemolition BuildingUnit Association to CP Association to AD officialarea officialvalue name specificinterest constructionnature numberofdwellings numberofbuildingunits Rarely available heightbelowground numberoffloorsbelowground materialofstructure materialofroof materialoffacade rooftype opengroundfloor energyperformance Status of cadastral specific data: core or extended profile? document

41 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 classification Mainly based on international More information to be found in use cases (air traffic, marine themes AF, PF and US navigation) Both code lists are extensible by member states Is this simple/rough classification of buildings suitable? How are themes BU and US articulated in your MS?

42 Consultation and testing

43 Calendar June 2011 Publication of data specification version 2 INSPIRE conference (Edinburgh) July-October 2011: review and testing November : PCC meeting 24-25: TWG BU meeting => Comments received but no decision taken yet

44 Testing SDIC/LMO Only transformation tests: -National data producers - Regional data producers (Italy, Spain, Germany) - Technology suppliers (Snowflakes) 15 registered testing SDIC/LMO

45 Commenting SDIC/LMO Most comments from national or local producers (+ EuroControl air traffic) Some registered testing SDIC/LMO have not submitted any comment

46 Received comments Theme BU: n 3 for received comments

47 Extension of scope Sources: - Questionnaire to PCC members - Comments (general review) Results: -19 SDIC/LMO: rather in favour of extension Agreement for extension (core profile) - 6 SDIC/LMO: disagreement with extension Agreement for extension (optional) Conflicting comments Disagreement for extension

48 Status of cadastral data Open issue: should (specific) cadastral data be in core profile? BuildingUnit Link to Address and Cadastral Parcel Official area, official value Question misunderstood Cadastral data should be in INSPIRE (e.g. detailed geometry, year of construction, number of floors,.) Specific requests to move links to Address and Cadastral Parcels to core (normative) profile Some issues foreseen Official area : feasibility Official value: privacy

49 Classification of buildings Sources: - Questionnaire to PCC members - Comments (general review) Results: - few answers - no clear trend Agreement for simple classification Eurostat classification Conflicting comments More detailed classification

50 New requirements More values in some code lists More attributes on Building Unit Use - official value Official area - energy performance Heating system and heating source Connection to networks Associations to US, PF, AF Area Floor description (height, number of dwellings) More detailed 3D model...

51 Other comments Need for more guidelines and better explanations BuildingPart BuildingUnit Interrogation about hierarchical code lists Articulation with theme US: still an open issue Code for official area Inconsistencies, editorial errors...

52 Next steps November: TWG BU meeting February 2012: version v2.9 (DS) March 2012: internal review, last X-theme harmonisation April 2012: version 3 (DS) answers to comments End 2012: Implementing Rule voted 2013: Implementing Rule published
